Yes - same hardware (3845), sw, config and traffic. Just deployed as active/standby for HSRP. The chief suspect is the port channel between the ESWs but would like to get the info to confirm whether its spanning tree or another culprit. Im unable to get any useful info out the box as when it occurs the CPU spikes and hits VTY so unable to get any commands back. Is there anyway to reserve a minimum amount of CPU to VTY so we can at least issue the commands while the problem is occuring?

If ones reloads then the CPU on the other hits 100% and crashes. The only way we can recover this is for a field engineer to pull all the Ethernet cables out and then, when system is calm, repatch them.

We have the situation that when RANCID grabs a config from an older 7204 with NPE-300 it causes the CPU to hit 100% for a long 4-5 seconds, which is long enough for OSPF with 1 second hello-interval to time out and declare neighbours dead. I've read the cisco doco on troubleshooting high CPU due to exec & vexec processes: http://www.cisco.com/en/US/products/hw/routers/ps359/products_tech_note09186a00801c2ae4.shtml I know that the problem is the volume of data being transferred to the telnet session, all I want to do is throttle it a little bit. I wouldn't be concerned if it took twice as long for RANCID to grab the config from this device if it helped stop the timeouts. Any suggestions appreciated.

We had a situation in the past where rancid would cause some 72xx and 75xx to crawl and sometime crash when accessing the disks. You may want to check if that's the case and comment out the offending command in @commandtable (around line 1700 of /usr/lib/rancid/bin/rancid) IIRC it depends on IOS version and type of ata disk used.

The problem is quite likely not the VTY speed, but the time it takes the router to generate the "ASCII config" from its internal tables. You yould try tweaking the scheduler, to preempt a process that takes so long (something like "scheduler allocate 1500 1000" or so).

Either way I don't think aggressive dampening is a good idea and is just a bandaid to the real underlying problem, you have instability inside your vrf's IGP, this may be due to link flapping, poor summarization, mis-configuration etc.. You need to address the issue of why you are seeing an unusual amount of updates, i've setup mpls vpns with 100+ CE's in a single domain with no excessive BGP update problem - unless there was an actual fault in the vrf IGP which was causing the BGP updates.

SXH lists VPLS as a feature because the chassis devices can take WAN cards, which do support VPLS. The ME6524 obviously doesn't take WAN cards, so can't do it.

Cat6500, dual-sup720-3B, SXH4. Two linecards - a 6748-GE-TX (no DFC) and a 6816A (DFC3). The switch acts as a "vendor nexus" - we connect to a bunch of exchanges, and it's the gateway between us and them. Most of the traffic is multicast coming in on various 1GB links, but there are also several outbound TCP connections, of the "stay up all day" type - connect in the morning, talk all day, shut down at 6PM. All of the TCP connections are NATted, generally with a different range to each different vendor (yes someday it would be nice to present one public routed space to all of them, but not all of them can handle it even if). Occasionally, it appears as though the 6500 will occasionally "confuse" one established TCP NAT connection with another. The effect is such that, given connection 1 between A (inside) port W and B (outside) port X and connection 2 between C (inside) port Y and D (outside) port Z, the switch will spontaneously start translating the incoming packets from B (previously being correctly translated to A port W) and send them to C port W instead of to A port W. Packets from A to B, however, will still be translated correctly. The result to the hosts involved is that B still receives A's packets, B still thinks it is sending packets to A... but A doesn't receive anything, and eventually the socket will time out and die (in various ways, depending on whether keepalive is set or if there's a heartbeat in the connection protocol or whatever). C gets the packets, but since it is invariably to an invalid port on C, C sends an RST to B, the switch sees a RST packet from C port W to B port X, doesn't have a NAT entry for that and presumably says "eh, what's the point", and the packet just drops. No errors of any type from the switch. It just notes the connection dropping (I have "ip nat trans syslog" set). And it's not all that common - it does it to one connection every odd few days. There are a bunch of NAT entries being created/deleted all the time from a monitoring host, mostly ICMP watching the far-end hosts. This was first seen in 12.2(18)SXF15a on a sup32; I upgraded to 12.2(33)SXH4 and the problem appeared to go away. (however, we also wrote code to detect dropped connections and restart more gracefully.) The problem has now appeared on SXH4 on a sup720. Or appears to have; the symptoms are the same in any event. Weird, huh? I have a sniffer on the inside to watch the traffic streams so I can capture it happening. The question is, what might I set for debug or poll from the switch in order to determine what the heck the switch is thinking when it's doing this? -bacon From pdavis at i2k.com Tue Sep 1 11:36:25 2009 From: pdavis at i2k.com (Philip Davis) Date: Tue, 01 Sep 2009 11:36:25 -0400 Subject: [c-nsp] NAT Ager CPU Usage Message-ID: <4A9D3F79.6020405@i2k.com> Hello, I have a 2621XM that is using more CPU on the NAT aging process that I would expect. At this moment that process is sitting around 15% with ~1700 entries in the NAT translation table. In comparison I have other 2621XMs at other sites doing 2500+ NAT translations where the NAT ager process is using <1% of the CPU. At times the NAT ager will use 50+% of the CPU still with relatively few translations. This causes problems. Does anyone have any idea why this may be happening?

If the servers are built offline, the automatic MAC address assignment can (and will) pick duplicate NICs. The solutions are to either build the servers in-situ or to maintain a list of allocated virtual MAC addresses and watch for duplicates. Good luck, David Barak Need Geek Rock?

BGP next-hop tracking helps, but doesn't completely remove the need for BGP scanner. I know SRB+ has it, not sure about SXH/SXI/etc or any other platforms. http://www.cisco.com/en/US/docs/ios/iproute/configuration/guide/irp_bgp_adv_features.html#wp1056214 Of course this just opens the door for new obscure ways for things to consume CPU and cause problems. The scheduler in newer IOS like SR is certainly a lot better, so when something does spike it is less likely to cause disruptions to the rest of the router. In theory the scheduler from modular IOS is much better too, but this only comes into play if the process you care about has actually been broken out and isn't running under the big ios main process. -- Richard A Steenbergen http://www.e-gerbil.net/ras GPG Key ID: 0xF8B12CBC (7535 7F59 8204 ED1F CC1C 53AF 4C41 5ECA F8B1 2CBC) From tomas at soitron.com Tue Sep 1 15:31:52 2009 From: tomas at soitron.com (Daniska Tomas) Date: Tue, 1 Sep 2009 21:31:52 +0200 Subject: [c-nsp] Leaking specific routes from a VRF In-Reply-To: <9445a3fb0909011149p1e744ecatf30cf3434d92aa2e@mail.gmail.com> References: <9445a3fb0909011149p1e744ecatf30cf3434d92aa2e@mail.gmail.com> Message-ID: <6B43981C32F8464CB24CEE209DA32BD302516F6C@kenya.tronet.as> > > In a working MPLS VPN scenario, is it possible to import and export > specific > routes between different VRFs? > You can use a VRF-level export maps to filter on export or to assign prefix-specific RTs.

Here's a little secret about surge protectors. Most of them flat out suck. Most of them are of no use unless the surge is extremely large such as what you'd expect from a lightning strike. In reality a surge protector should clamp down at 150v or less. I saw a demo once of several different brands of surge protectors that we supplied to a distributor of another brand. Most of the ones we'd supplied had apparently already been hit and had blown the pot. A few were actually good. 200+ volts passing through them and they still hadn't tripped. The APC actually melted in the demo (which explained the concrete board they laid on our table under the surge strips). Then the reseller brouht out a Panamax surge protector. He started walking up the voltage from 110. At around 140v it tripped. Walked it back down and the surge strip came back on. It doesn't fry itself tripping like most of the other brands do. Then he walked it down from 110v. At around 90v it tripped as well. It cuts off for under-voltage which is a major problem in the rural areas I come from. http://www.panamax.com/Products/Floor-Models/M8-EX.aspx I would highly recommend Panamax brand surge protectors to anyone. Not all of them cut off for under-voltage so look at the specs carefully. The one I linked to does of course. It's worth the slight premium to buy the good stuff. I don't buy anything else anymore. We didn't test Tripp Lite so I don't know how they stack up. For $40 you can be sure though with a good Panamax. One thing that you might consider is placing a decent manageable UPS in your rack. You don't have to put a load on it. Use it to monitor the line condition for irregularities. Manageable UPSs tend to be much cheaper than commercial power quality monitoring equipment. With that data in hand you can approach your colo provider.

Does it mean that I have to run a dedicated grounding wire to every piece of equipment? The racks are properly grounded (according to provider) and every server is screwed to them. The power is provided via NEMA L5-20P twisted lock connecter with proper grounding (according to provider). There I currently have tripp lites followed by managed APC PDUs. All equipment is plugged in into APC grounded outlet. Does it not qualify for "proper grounding"? I also personally went there with a voltmeter and check for voltage between metal parts per Seth Mattinen suggestion and I found 0 voltage. This may sound silly, but I'm taking any chances.

Each device receives ground through the power cord (3rd prong is there for a reason, as well it is tied to chassis ground internally). Secondly, the cabinets themselves should be grounded as is the case in any proper facility. By fastening the chasis to the cabinet you are basically providing a second ground path. A third ground path is nice and pretty, but it isn't going to do much if anything at all to help him in this case. Either the power is extremely dirty, or the facility as a while is not properly grounded which means no matter how well he grounds his equipment it won't help unless he digs his own ground. -- Randy ---------- Original Message ----------- From: Justin Shore To: Michael Ulitskiy Cc: cisco-nsp at puck.nether.net Sent: Tue, 01 Sep 2009 14:19:50 -0500 Subject: Re: [c-nsp] Multiple power supply failures.

That's why most telco screw kits come with the star washer to help scrap the paint of the rack and why most telco equipment frames and mounting kits are a non-painted alloy. Data equipment isn't generally made to the same standards. So for example if you rack up a 3750 you're using non-painted mounting brackets on a painted 2-post. The chassis is also painted so you most likely aren't making a connection between the chassis and the bracket and thus not the 2-post. The ground in the power plane should never be connected within the chassis to the chassis itself. The power plane should never share anything common with the chassis. The chassis should always be grounded separately. Now beyond the panel at the site ground they'll likely meet up again but within the powered equipment they should never touch. Ie, the ground conductor in the L5-20R that your colo provider dropped in your cage should not internally connect to the chassis of the device. The electronics within the device should be insulated from the chassis and the chassis should have an external ground connection that you connect either to the frame or to a ground bar on the frame. Depending on the equipment (thinking telco for a minute) the equipment is sometimes insulated from the frame and connects to a ground bar that is also insulated from the frame as well. There are a lot of telco standards out there that are meant for specific applications. Bottom line, always ground the chassis with the supplied hardware either to a grounded frame or to a ground bar within the frame that goes back to a site ground bar. Not all manufacturers adhere to those standards though... Justin Michael Ulitskiy wrote: > Sure, but what the proper grounding is?

The lug will let you beef it up and do a 6AWG or whatever instead of what's in the power cords, but the ground is tied everywhere. It has to be; it's a safety ground. Something really odd/fishy is going on at the facility in question. Either they have a problem and won't admit it, or they're just as baffled as you are. But there is obviously *something* very bad going on to fry power supplies like that. Which leads me to a question; has any of the stuff you've replaced become part of the fried PSU problem, or just originally installed supplies? One tells me they're lying and the power is even worse than a raw utility feed, the other says maybe you have metal particles (or something) building up from under the raised floor over time. ~Seth From john at vanoppen.com Tue Sep 1 19:24:36 2009 From: john at vanoppen.com (John van Oppen) Date: Tue, 1 Sep 2009 16:24:36 -0700 Subject: [c-nsp] Multiple power supply failures.

The only time I have ever seen this is a floating positive side on -48v gear, but even that is not terribly common. We have several POPs that are on the tops of hills where we are exposed to lighting and I can say that not having all of one's grounds bonded is a really bad idea. Contrary to popular belief, grounds are not really required to be at the same potential to the ground but rather to be the common potential across the entire site, preventing current from flowing across the data circuits between pieces of gear by providing the lowest resistance path for any leakage or differentials between the gear. This common electrical plane is earthed due to safety and static dissipation reasons since it would be bad from a safety prospective to have the racks at a different potential than the ground the people are in the building are standing on (let alone a pain for copper data circuits). --John -----Original Message----- From: cisco-nsp-bounces at puck.nether.net [mailto:cisco-nsp-bounces at puck.nether.net] On Behalf Of Justin Shore Sent: Tuesday, September 01, 2009 3:03 PM To: Michael Ulitskiy Cc: cisco-nsp at puck.nether.net Subject: Re: [c-nsp] Multiple power supply failures.

The chassis should always be grounded separately. Now beyond the panel at the site ground they'll likely meet up again but within the powered equipment they should never touch. Ie, the ground conductor in the L5-20R that your colo provider dropped in your cage should not internally connect to the chassis of the device. The electronics within the device should be insulated from the chassis and the chassis should have an external ground connection that you connect either to the frame or to a ground bar on the frame. Depending on the equipment (thinking telco for a minute) the equipment is sometimes insulated from the frame and connects to a ground bar that is also insulated from the frame as well. There are a lot of telco standards out there that are meant for specific applications. Bottom line, always ground the chassis with the supplied hardware either to a grounded frame or to a ground bar within the frame that goes back to a site ground bar. Not all manufacturers adhere to those standards though... Justin Michael Ulitskiy wrote: > Sure, but what the proper grounding is?

Instead, if you note the quotes, Drew is concerned with the impact of the CPU consumed by BGP scanner on 'system' performance. This concern does not exist on modular platforms with distributed packet switching (c12k, hfr etc.) that switch packets independent of main RP CPU. Put simply, even if BGP scanner maxes out an RP CPU at 100% temporarily on a distributed platform, it will have zero effect on packet switching (a la 'system' perf) through the device. Your thoughts below dwell more on enhancing the mechanism to reduce frequency. -Eninja ;-) On Tue, Sep 1, 2009 at 5:36 PM, Richard A Steenbergen wrote: > On Tue, Sep 01, 2009 at 03:56:02PM -0700, e ninja wrote: > > > > *BGP scanner is a housekeeping maintenance activity by the main system > > processor.

Also I do want to thank you for your reply. At this point I really doubt that the problem is grounding related, but I'll definitely keep that in mind. Also in my experience I've never seen a place where every piece of equipment would have a separate grounding wire attached to the chassis. As far as I can tell this is a standard procedure: grounded outlet, grounded racks and equipment screwed to the racks.

Out of the 7 failed PSUs 6 was original equipment. One cisco gear (AS5400) has power supply failed twice. The 2nd failed power supply had been in service like 24-48 hours only before the failure, so may be it was just bad power supply. I'm leaning toward metal particles build up as a most plausible theory at the point. I just don't know how to deal with the problem...

They are doing work in the facility. Not heavy construction, but they do install cages and cabinets for new tenants and they're definitely using tools that produce metal dust. My theory is that because of we've been the 1st customer who moved into that facility we've been collecting that metal dust for longest and so we're having a lot of problems with our equipment. To my knowledge none of our neighbors are having the same problem, but none of them have been in the place long enough. So the question remains: is there any way to fight it/protect from it except from going through the huge-huge-huge headache of undertaking another move?

That's about the only thing I'm more or less sure about. This is not a cabinet, but an open cage with 6 open racks installed.

I had a look and the @commandtable array contains the following three lines: {'more system:running-config' => 'WriteTerm'}, {'show running-config' => 'WriteTerm'}, {'write term' => 'WriteTerm'}, Which I assume are to make sure it can get the config from multiple different types and versions of Cisco devices. All of these commands work on a 7204 (which means it was getting the config three times I think), so I've commented out two of them so it's only executing a single "show run" command. This seems to have helped quite a lot with the OSPF timeouts. I've cranked up RANCID to run every 10 minutes to flog the poor box to death and see if it will definitely not interfere with OSPF now. If it still does then I'll have to drop back to 2 second hello intervals which should definitely resolve all of the problems. Thanks for the suggestion of changing the "scheduler allocate" parameters Gert. I went and read some documentation and tried changing it around a bit but it didn't appear to have any beneficial effects at all ? One thing that I've just discovered that puzzles me is that the OSPF neighbour drops are only on ONE of the links that come into this 7204. It has neighbours on the interfaces Fa0/0.3, Atm1/0.2 & Atm1/0..3. It is only the neighbour on the Fa0/0.3 interface that is dropping, the two connected via ATM are not dropping at all. Is there any logical reason for this ? Is it because I'm using the 10/100 port on the I/O module ? Would it be any different if the ethernet interface was on a PA instead ?

Company is planing to deploy IP telephony in the network covering 2 remote sites and head quarter. here is my plan: 85pcs x CP-3911 (Cisco SIP Phone 3911) 1pcs x MCS7816H3-K9-CMB1 (Unified CM 6.0 7816-H3 Appliance, 0 Seats) 2pcs x LIC-CM-DL-100= 1pcs x LIC-CM6.0-7816= (License Unified CM 6.0 7816 Appliance, 500 seats) My question is this: 1. What is the DLU for CP-3911 (Cisco SIP Phone 3911) device? Based on that I can calculate number of LIC-CM-DL-100= license 2. What is LIC-CM6.0-7816=(License Unified CM 6.0 7816 Appliance, 500 seats) license, is it the one for CM application software license. Because I got this line from the Communication Manager v6.0 documentation. Application and phone software licenses are enforced. 3. Is there any other LIC-CM6.0-7816= license which has few seats, maybe around 100. By the way, what is a seat here. Seat, does that mean the total number that Comunication manager can manage upto? 4. If I go for Unified CM v7.1 then what is the part number for that with MCS appliance? thank you in advance.

(i know that with CFC we're limited to the backplane (32mpps?) and we get ~ 48mpps per blade with DFC) ...or could it be that DFC's are only really useful to a particular deployment and I just *think* i need them? ;-) alan From gkg at gmx.de Wed Sep 2 07:58:25 2009 From: gkg at gmx.de (Garry) Date: Wed, 02 Sep 2009 13:58:25 +0200 Subject: [c-nsp] VPN traffic to the Internet ... Message-ID: <4A9E5DE1.7060808@gmx.de> After trying to get this to work for a while, I'm somewhat out of ideas ... I have a (otherwise working) VPN-connection from Windows clients (using Cisco VPN client) to an ASA, IP traffic from and to the internal network is working just fine. Now the problem comes up that the clients need to reach a site on the internet that is only accessable from certain IP ranges, which the mobile clients do not fall into. I thought, well, no problem, just extend the split tunneling to the destination IP.

Agreed, and introducing DFCs can give you some headaches with e.g. policers, since each forwarding engine operates independently from the others.

It is an entirely software mechanism which periodically walks the entire bgp table and does things like verify next-hop reachability. Distributing the operations that it performs so that they happen when a prefix or next-hop changes is a much better way to handle things (improves convergence and reduces the periodic cpu spikes), but you'll probably never see it go away completely. :) -- I didn't assume the actual process BGP scanner would go away, I was simply wondering why as everything (Moore's law) gets much, much faster, this process still has such a impact on the even highest end RPs. I would assume that the "utilization" impact on the RP would go down as the $$$ of the hardware goes up, but I suppose if it all runs in software and isn't using the features of the more expensive RPs then it will just "be slow forever" ;-) I guess you can liken it to a PC without discrete graphics, you can have the best CPU in the world but if you are rendering polys in software, it's still going to chug. -Drew From asturluismi at gmail.com Wed Sep 2 08:56:40 2009 From: asturluismi at gmail.com (luismi) Date: Wed, 02 Sep 2009 14:56:40 +0200 Subject: [c-nsp] SXI, TACACS+ in VRF In-Reply-To: <6B43981C32F8464CB24CEE209DA32BD302517107@kenya.tronet.as> References: <6B43981C32F8464CB24CEE209DA32BD302517107@kenya.tronet.as> Message-ID: <1251896200.11377.7.camel@dsba-ipso> did you tried "test aaa" command?

Instead, if you note the quotes, Drew is concerned with the impact of the CPU consumed by BGP scanner on 'system' performance. This concern does not exist on modular platforms with distributed packet switching (c12k, hfr etc.) that switch packets independent of main RP CPU. Put simply, even if BGP scanner maxes out an RP CPU at 100% temporarily on a distributed platform, it will have zero effect on packet switching (a la 'system' perf) through the device. Your thoughts below dwell more on enhancing the mechanism to reduce frequency. ------------- Yes, but the confusion in (my mind, anyway) is that sometimes when the RP is at high CPU utilization forwarding performance is affected. i.e. in the case of a DoS attack, although I suppose that the RP being at high CPU utilization is a 'by-product' of the forwarding hardware punting so much crap to the RP and not vice-versa. So when monitoring the CPU for these kinds of events it can be hard to tell in a programmatic way whether it's just BGP scanner, or something more nefarious like a TTL Expiration attack, or any of the other 700 types of DoS/DDoS style attacks which take place these days. I suppose the real question is, what do you monitor on a modular/distributed system in order to gauge the performance, if not the CPU on the Route Processor? are there OIDs for the discrete switching/forwarding engines? I know at least on the GSR platform each line card has its own CPU/memory statistics available, which is at least ??somewhat?? helpful in quickly identifying a problem. -Drew From jared at puck.nether.net Wed Sep 2 09:03:18 2009 From: jared at puck.nether.net (Jared Mauch) Date: Wed, 2 Sep 2009 09:03:18 -0400 Subject: [c-nsp] do i *need* DFCs on the 6500?

Many Cisco devices work this way also. I have rarely seen a power supply that sucks air in directly from the outside of the chassis. Given the above, much of the dust would settle on the system board. The extremely high tolerances of a typical system board far outweigh those of a power supply, thus I would expect system instability before the power supply failed. My bet is still on power spikes/dips. -- Randy www.FastServ.com ---------- Original Message ----------- From: Michael Ulitskiy To: "Randy McAnally" Cc: cisco-nsp at puck.nether.net Sent: Wed, 2 Sep 2009 11:08:24 -0400 Subject: Re: [c-nsp] Multiple power supply failures.

In-Reply-To: <4A9E6786.5010901@justinshore.com> Message-ID: The PFC is capable of the same things as a DFC, just in a centralized manner. So, for example, CoPP works just fine in hardware with a PFC - you don't NEED to offload the QoS to the LCs. You need a DFC only if some resources are close to exhaustion (like pps rates supported by centralized forwarding, netflow entries, QoS entries and so on).

This is the best way to ensure that you are getting the proper waveform, and that your power is free from transients and sags. A normal managed UPS will not be able to pick up infrequent spikes, harmonic distortion, etc. These are all single phase 120 volt circuits, right? Grounding is unlikely to be the problem. As previously mentioned, the safety ground on the equipment power supply bonds the equipment chassis to the facility ground. This is adequate in a typical data environment that is not in a high lightning exposure zone. If you were in a telephone CO, a site with a communications tower, etc., then it would be worth your while to make sure that each piece of equipment and metal hardware was bonded back to the MGB. But based on the information you've given here, I don't think this is relevant to your power supplies blowing up. I would go ahead and put some double sided tape on the air intakes for your equipment. After a few days, peel the tape off and take a look at it using a microscope or magnifying glass and inspect for metal particles.

It really doesn't matter which side you enable as the receiver, but I try to stay away from pre 7.x code on the PIXes. packet-tracer input inside icmp 10.1.0.10 8 0 10.18.15.10 detailed Phase: 10 or 11 should be subtype encrypt. If it fails the first time, run it again, the negotiation process causes the first packet to fail as the tunnel is being brought. This type of traffic will also give you your debug information and help you figure out where the failure is. -ryan -----Original Message----- From: cisco-nsp-bounces at puck.nether.net [mailto:cisco-nsp-bounces at puck.nether.net] On Behalf Of Scott Granados Sent: Tuesday, September 01, 2009 8:29 PM To: cisco-nsp at puck.nether.net Subject: [c-nsp] ASA5520 to Pix can't bring up IPSEC L2L tunnel Hi, I have a Pix out in the field and an ASA5520 that I'm trying to configure to pass L2L traffic.

Running SRA/SRB/SRD, we have seen a few instances (>5) of the "real" running config being out of sync with the output of show run interface. Problem was easily cleared by removing/reading the parser cache command. Have not tested the scp results under those circumstances. The benefit of the config cache is significant. Loaded chassis without cache sometimes take maybe 30-60 seconds to begin outputting from a show run.

Message-ID: Hi I have a question regarding AS numbers, whats the best solution, and pros/cons with the different setups? Let say there is an MPLS provider, and one customer has a HUB-site with dual CPE in the VPN. Each CE router is connected to 2 different PE routers. Behind each CE router the customer has a Juniper router and are using eBGP to peer with us. They want per session loadsharing between the to CPEs. The MPLS provider are not planning to run iBGP between the CE routers. Only eBGP to the PE. Now, should these 2 CE routers belong the the same AS number? Let say, 100. Or should they be in separate? 100, and 200? You should still be able to loadshare with max-path eibgp 2 on the PEs even if they are in different AS numbers right? It is only the AS path lengt that is compared, not the actual number if im not misstaken. Any pros/cons with the different setups, same AS, different AS. Thanks!

Assuming you have nothing else logging to monitor, you can enable 'logging class vpn monitor debug' and throw up a term mon to gather inbound messages to the ASA from the PIX side. You can gather the information on the PIX with a debug cry isa 2 and then initiate interesting traffic from the ASA using the following, the more valuable information will be on the receiving end. It really doesn't matter which side you enable as the receiver, but I try to stay away from pre 7.x code on the PIXes. packet-tracer input inside icmp 10.1.0.10 8 0 10.18.15.10 detailed Phase: 10 or 11 should be subtype encrypt.

We have a 7500 series router, RSP16 with IOS Version 12.3(21) terminating a bunch of ATM circuits. We have 3 ATM DS3s terminating on PA-A3-T3 cards, and an ATM OC3 terminating on a PA-A3-OC3-SMI. All line cards are VIP-480s. The problem we are seeing is customers with PVCs on our ATM OC3 have begun getting extremely poor throughput. 30mbit PVCs that can pull at most 3-5mbit/sec. Overall utilization of the ATM OC3 dropped from around 90mbit/sec last year to around 25mbit/sec this year. We've had the LEC test the OC3 and the customer side (DS3s to multiple customers) at the ATM PVC level and show us results that the OC3 is able to push 155mbit/sec worth of cells and the DS3s are able to push 45mbit/sec worth of cells. There are no errors on the interfaces and no AAL5 errors on the PVCs. We're completely at a loss. One commonality we've found is that when we ping the opposite side of a customer on one of the ATM DS3s in our chassis with large packets it works fine. Pinging a customer on our OC3 with any packet larger than 576 bytes intermittently fails. ATM DS3: er02.penn-nj#ping x.x.x.x size 577 repeat 1000 Type escape sequence to abort.

For example, have an ACL called vpn_ny and ACL called inside_nonat, then as you add new partners, you'll have a new interesting ACL and a new addition to your nonat ACL. As for versions, if the PIX is a 515, that is a scary upgrade and will most likely require someone onsite to upgrade it from the bootloader. If it's a 515E, the upgrade can be completed with a lot less risk. Either option requires a minimum memory upgrade to 64 Meg. We have a lot of luck with 7.2.4(33) interim release. -ryan -----Original Message----- From: Scott Granados [mailto:gsgranados at comcast.net] Sent: Wednesday, September 02, 2009 1:44 PM To: Michael K.

Do you lease > (meaning paying a MRC) or is it 'purchased' (meaning a NRC)? In a case like this, it's commonplace to lease fiber from a fiber provider. Depending on your location, there might be several who can provide you with the glass you're looking for. In a scenario like this, you're normally leasing the fiber, or possible purchasing a long-term IRU (Indefeasible Right to Use). Charges are normally based on mileage and any necessary construction at either/both ends to get the fiber from their existing plant into your buildings. Some providers will amoritize the construction costs into your monthly contract rate, while others will require you to pay for the construction separately. Depending on the number of strands you need between points A and B and other considerations (multiple routes to provide physical diversity, etc), the provider might be willing to build a path for you, but the cost goes up dramatically. Once the fiber path is completely built, make sure the provider gives you the results of their tests (2-point loss, OTDR graphs, etc) on the whole span. The performance of the fiber and the type of optics you'll need to drive the link over distances of 'a few miles' will normally have much more to do with the quality and number of splices than the length of the span itself. I've driven 1000baseLX/LH signal cleanly over fiber paths that were longer than 10km as long as the 2-point loss is under the link budget for the optics. jms From jim at jamesberwick.com Wed Sep 2 15:59:06 2009 From: jim at jamesberwick.com (James Berwick) Date: Wed, 02 Sep 2009 15:59:06 -0400 Subject: [c-nsp] ATM packet loss In-Reply-To: <20090902193755.M55542@fast-serv.com> References: <4A9EB3FF.9070805@jamesberwick.com> <20090902193755.M55542@fast-serv.com> Message-ID: <4A9ECE8A.8010001@jamesberwick.com> Nope: er02.penn-nj#show run | i mls er02.penn-nj# er02.penn-nj#show mls rp interface atm 1/1/0 mls not configured on ATM1/1/0 er02.penn-nj#show mls rp interface atm 1/1/0.36 mls not configured on ATM1/1/0.36 er02.penn-nj#show mls rp ip ip multilayer switching is globally disabled Randy McAnally wrote: > Do you have QOS enabled (mls qos)? > > -- > Randy > > ---------- Original Message ----------- > From: Mikael Abrahamsson > To: James Berwick > Cc: cisco-nsp at puck.nether.net > Sent: Wed, 2 Sep 2009 21:01:15 +0200 (CEST) > Subject: Re: [c-nsp] ATM packet loss > > >> On Wed, 2 Sep 2009, James Berwick wrote: >> >> >>> works fine.

Is it a switch that is actually doing QinQ? I have run into problems before where I had a metro-Ethernet link provided to me by a provider that used QinQ. So, none of my switches were speaking QinQ. The problem I ran into is that my 6500 switches use the same MAC address for every "interface vlan" on the switch. I then had half of my spanning tree roots set to one switch, and the other half set to the other switch. This resulted in the same mac address being transmitted in both directions around my redundant metro-e loop. None of MY switches ever logged the "is flapping between..." message, but my provider did get that message logged constantly. For me, it just looked like I kept losing connectivity because whenever the mac address went one way, one half of the vlans worked. When it went the other way, the other half of the VLANs worked. Here's an old diagram I prepared years ago explaining the situation: http://www.overloaded.net/pics/qinq.gif You won't run into this problem if a) you never reuse a mac address across VLANs, or b) all your STP roots are the same, or c) you don't have redundant links forming a loop that includes QinQ. The average customer of a QinQ metro-e provider likely won't notice this issue mostly because of "C". I suspect most customers of metro-e providers using QinQ probably aren't using the QinQ based link to form a redundant loop. In my case, I almost always need redundant bridging of all VLANs between datacenters. Our solution? We now ask every provider that we might buy metro-e from if they are using QinQ. If they say yes, they are disqualified. Unfortunately, some say no but turn out to be using it after all. It is quite frustrating to spend lots of money and time trying to get a provider to turn a circuit up in time for a big project only to find that once the circuit is delivered, we can't turn up redundancy across it because the circuit is unable to carry reused MAC addresses across different VLANs.

I have migrated customers from one city to another nearby city across <5 ms links by bridging their VLANs across the circuit (outer and inner VLANs), then moving one firewall of a failover pair one night (leaving things running for a day or two with failover across datacenters), then the next night failing it over to the firewall in the new DC and moving the 2nd firewall. This lets us do "hitless" firewall migrations from one DC to another. Downtime for the 1 forced failover required to complete the process is sub-second, and stateful failover allows connections to survive. We haven't ever left it split like that long term, but I haven't noticed any problems in the day-or-two migration situations we've done this for.

Telcos are doing something similar for ages - they are deploying physically separate networks for management and they know very well why they do so. IP equipment is just getting there, e.g. Nexus has dedicated management ports which are forced into a management VRF. > What are the benefits from using a VRF for this? It's kind of mimicking separate control and forwarding planes. Though the separation is virtual, it's still better than none. > I assume everyone uses infrastructure ACLs so the VRF thingy shouldn't > be any more "secure". Or should it? First, ACL is reactive mechanism, management separation is proactive. You prevent unwanted stuff from entering your management network even before you can filter it. Second, you isolate problems - think your IGP not working because of whatever reason (attack, misconfiguration...), but you still can ssh your box via the (quasi) out-of-band management, which you don't touch at the same time, and repair the network. Etc.

Continuous pings of 576 bytes work flawlessly. 577 byte pings show between 1% and 2% packet loss. We don't maintain the ATM network between us and our customers. The LEC that does has gone to two of our customer's facilities and put an ATM test kit on the DS3 and tested sending 45mbit/sec of cells across that particular customer's PVC. We've then looped the OC3 in the router with loopback line on the ATM1/1/0 interface and they saw 45mbit/sec worth of cells returned. I'm not sure where to look for a cell policer. This OC3 comes from the LEC into our 7500 series and we don't have any QoS or rate limiting on the ATM interface itself or any of the PVCs. I'm not sure if this is helpful information or not but if we use something like speedtest.net from a customer's network we end up with results like 5mbit down, 30mbit up. It seems like the throttling is taking place in only one direction, but we aren't (intentionally) doing it on our router and the LEC who handles the ATM cloud swears up and down they aren't doing anything that would cap throughput and none of the switches between us and the customer are oversubscribed. I just tested now by kicking off enough ping -f x.x.x.x -s 548's (Ping flood with 576 byte packets) to push 20mbit/sec worth of ICMP traffic across a PVC with 0% packet loss, while the same test with a 1000 byte ping fails miserably. I'm at a loss as to why either our router, our LEC's ATM network (which according to them is doing no policing at all of our UBR traffic), or a dozen of our customer's Cisco routers have all suddenly decided that packets over 576 bytes need to get dropped on the floor randomly.

It would also be nice if more network devices had truly isolated management ports such that bearer/management traffic never have to cross paths, share routing tables, and so forth. Various IOS versions also do not have syntax to tell the router to send syslog / snmp trap / tacacs via the management VRF, defaulting instead to the global routing table. This can be worked around with some effort, but it's an annoyance. Plus if you have instability in your network environment for any reason, you don't want to be reliant on that unstable network to get access to the routers so you can fix it - you're working on the very transport you're relying on for connectivity. That said, it can be done with some careful planning, and especially if you have out of band console access as a 'back door' in case of bad connectivity issues, you may have a reasonable compromise without having the expense of parallel management infrastructure.

Multihop BGP is not a good idea in this example. You'll want to use something like neighbor x.x.x.x allowas-in on your eBGP sessions. However, you'll also want to setup a BGP filter to deny your own sourced prefixes to prevent loops/flapping. Meaning, when you allow prefixes from site A into site B, setup a BGP filter on site B denying B's prefixes and vice versa.

Research has indicated SOME interfaces are supported, loopbacks for example, but I can find no definitive of which ones are supported. Or... in the past 3 years has there been any IOS releases which may have updated it. I saw a brief post which wasn't complete in which someone used a line card to loop the Ethernet back or somesuch to get SVI's into a VRF.... but I couldn't find anymore. Essentially VLAN's or SVI's is what I want to get into a VRF, and it would be nice for layer 3 interfaces as well... but I will take what I can get. Does anyone have any creative ideas on how one might accomplish this? i.e. using one of the maybe supported WAN cards (is there a list?) in which we could accomplish the same result.

Assuming you have no default route learned via eBGP then (given 3 full routing tables, that's probably a fair assumption), the question becomes whether you can intelligently maintain a floating static default based on reachability to the next-hop IP, or if it's better to implement some kind of BGP peering between the two sites. One possibility might be to consider a conditional static default route - use "ip sla" to test next hop reachability of a provider's router, then use the track command to monitor and apply to a floating default route (and of course, you can do this for more than one provider and provide a predetermined sequence of alternate default routes) I am not personally a fan of iBGP "raw" over a public network (and that's what it would be since the ASNs are the same on both ends), as most of the protection features in IOS are focused on eBGP. GRE tunnel works, though there may be caveats depending on MTU/fragmentation issues and hardware switching support. Maintaining those BGP peers of course assumes that the remote IP in each case is known in one of the active eBGP sessions at all time. Probably a reasonable assumption if you're using provider-owned IPs to peer; maybe less so if you're using IPs that fall within your own larger block. I may be misunderstanding something about your particular topology, so my apologies if so.

I blocked one of the /16 network , which was flapping at a higher rate , coming from CE.

PA-A3-OC3* cards in > VIP2-50:s or are you using better gear? > Ok, to test I just built a 120 meg ubr pvc. It performed identically to the 45 meg PVC we've been testing with. I also built several other speeds (30, 45, 60, 90) and they all performed identically, packet loss for packets over 576 bytes and download speeds in the 1-5mbit range. The hardware is a Cisco 7507 chassis with an RSP16 with 1GB of RAM. The VIP is a VIP-480 with 256 megs of RAM. The only port adapter in the VIP is a PA-A3-OC3-SMI. The RSP CPU load averages 20% and show proc cpu hist does not show any time period that the max CPU broke 50%. The RSP has approximately 850 MB of free RAM. if-con'd into the VIP, it has about 190 megs of free RAM and shows an average utilization between 0% and 10% over the past 72 hours, no maxes higher than 20%. Our MRTG graphs show that September of last year this same hardware was pushing over 100mbit/sec on our ATM OC3. This chassis only does ATM traffic. We have a Covad ATM DS3 in a VIP2-50 in slot 0. This DS3 is working fine. We have a Verizon OC3 in a VIP-480 in Slot 1. This is our problem OC3. We have VIP-480s in slots 4 and 6 also terminating Verizon ATM DS3s, these are also working fine. We also have a VIP-480 in slot 5 with a gigabit adapter to uplink the router to the rest of our network. I just realized something that may (or may not be) helpful. We use ATM mostly for schools and other educational institutes, but we also receive residential and business DSL traffic over our ATM circuits. We've got around 400 DSL customers on this OC3 who are online right now, with a mixture of PPPoE and statically bridged DSL users and I'm not seeing anything wrong with any of their connections, ie, no packet loss, no performance issues. Please excuse me if I missed something or typed it very poorly, I've been working on this problem for about 18 hours now and I'm fried. Thanks again for the suggestions!

Increasingly, for many purposes, yes. Note that you can specify a VRF as the destination for NDE NetFlow telemetry, for example. Also, Cisco's Nexus 7000-series IDC switches allow the control and management planes of the switch to be separated into four Virtual Device Contexts, or VDCs. For the first time, a piece of general- purpose hardware can safely be used to carry both production and OOB management/Data Communications Network (DCN) management-type traffic across the same physical hardware. ----------------------------------------------------------------------- Roland Dobbins // Sorry, sometimes I mistake your existential crises for technical insights. -- xkcd #625 From jdurand at renater.fr Thu Sep 3 04:17:02 2009 From: jdurand at renater.fr (Jerome Durand) Date: Thu, 03 Sep 2009 10:17:02 +0200 Subject: [c-nsp] Management stuff in VRFs In-Reply-To: <1251920188.2923.4.camel@abehat.net.rm.dk> References: <1251920188.2923.4.camel@abehat.net.rm.dk> Message-ID: <4A9F7B7E.9030202@renater.fr> We went in that direction in our latest deployment and discovered also that many pieces were missing in IOS and IOS-XR to have full management in a dedicated VRF for all our devices.

A DFC3 does 48Mpps IPv4 (and 24Mpps IPv6). http://www.cisco.com/en/US/products/hw/switches/ps708/products_qanda_item09186a00809a7673.shtml A fully-populated and fully-DFCed 6509 does 400Mpps IPv4 or 200Mpps IPv6 (well, actually 192Mpps - 24x8 linecards). In this configuration, the PFC does very little. It's worth noting that a 6724 doing 64-bytes packets on all ports offers ~47Mpps forwarding load - well in excess of the PFC capacity. A chassis full of 6724s without DFCs at 10% load with 64-bytes packets also exceeds the PFC capacity. Obviously these are worst-case numbers but illustrative of the problems you can get yourself into if you don't capacity plan well. It's worth noting that some linecards have different (i.e. more flexible) rx & tx queueing methods with a DFC versus the CFC. There's also the bus-stall issues, which go away (supposedly) with a DFC installed since they're not connected to the bus. > you are even remotely close to this, and the global ipv6 routing table is no > where near the cam limit for that either, by the way is your SUP an XL? does > the DFC's on the 10G's match the sup or have they fallen back to the lowest > common configuration? I'm not sure why you mention CAM limits, but it's worth noting that DFCs do not help with FIB CAM at all, since they hold a copy of the PFC FIB. Personally we get DFCs on everything since we're using plain -3B (or -3C not) rather than XL, and the cost of the DFC is a pretty minimal percentage of the linecard for the future-proofing. We've also seen software bugs manifest on CFC cards in the past; this implies to me that Cisco "prefer" DFC chassis. Similarly some of the new linecards e.g. 6708/6716 are DFC-only. I suspect that will be the case going forward.

Interesting.. i'll take your word for that, can't say i've seen much in the way of bus stalls when working with them(at least in recent times) except the standard OIR one, i'll assume this is an actual performance impacting stall you are referring to, does this apply even if the chassis is in compact mode? > > > you are even remotely close to this, and the global ipv6 routing table is >> no >> where near the cam limit for that either, by the way is your SUP an XL? >> does >> the DFC's on the 10G's match the sup or have they fallen back to the >> lowest >> common configuration? >> > > I'm not sure why you mention CAM limits, but it's worth noting that DFCs do > not help with FIB CAM at all, since they hold a copy of the PFC FIB. > Yeah my ipv6 FIB CAM statement was pretty irrelevant and was more me typing then realising i'm not sure if we are even talking XL or not here, wasn't the greatest sentence. > > Personally we get DFCs on everything since we're using plain -3B (or -3C > not) rather than XL, and the cost of the DFC is a pretty minimal percentage > of the linecard for the future-proofing. > No doubt it's better to have a DFC than not have a DFC but some companies are tight with money and justifying just a few thousand for something you don't *really* need can be hard, while non XL upgrade might seem trivial I think you'll find to upgrade a 6724 from stock to a 3CXL DFC is around the price of the actual line card itself, that said neither of us know what PFC the OP is running :) > > We've also seen software bugs manifest on CFC cards in the past; this > implies to me that Cisco "prefer" DFC chassis.

I still get the feeling the OP doesn't need the DFC, generally you know if you need one as it's not something you think ooo that might be nice to have i'll take 5! you are normally saying I need X because Y doesn't work or Y will stop working in the near future, maybe the OP has a valid reason for needing it, I just didn't see it and don't want him(or his company) to buy something they don't need.

The chassis bus stall is done by 3 physical pins in the slot, so DFC or not you still stall and potentially reboot the chassis while inserting/removing a card- however DFC enabled line cards are not subject to the packet loss associated with a bus stall [1]. ~Matt 1: http://www.cisco.com/en/US/products/hw/switches/ps708/products_qanda_ite m09186a00809a7673.shtml#qa4 From rsm at fast-serv.com Thu Sep 3 09:37:59 2009 From: rsm at fast-serv.com (Randy McAnally) Date: Thu, 3 Sep 2009 09:37:59 -0400 Subject: [c-nsp] BGP multihop between two sites In-Reply-To: <15407A77-34F6-4B8D-AB41-DE8CBBE3E991@mimectl> References: <1251920188.2923.4.camel@abehat.net.rm.dk> <6B43981C32F8464CB24CEE209DA32BD3025171B7@kenya.tronet.as>, <20090902204250.M69344@fast-serv.com> <3BA4D8A8-4A4D-483A-9B80-9A1524F46062@mimectl>, <20090903010632.M90344@fast-serv.com> <15407A77-34F6-4B8D-AB41-DE8CBBE3E991@mimectl> Message-ID: <20090903133422.M65689@fast-serv.com> No, I think you understand it perfectly. The goal is to have 'stateful knowledge' of my own eBGP routes, using the simplest most resilient and cross-platform compatible method. What would be the caveats of the neigbor x.x.x.x allowas-in?? It seems too easy, there HAS to be a catch!? :) Do I need to change my inbound filters?? Right now I am not filtering inbound routes from the directly connected Tier1's. -- Randy ---------- Original Message ----------- From: To: , Sent: Wed, 2 Sep 2009 21:42:22 -0500 Subject: RE: [c-nsp] BGP multihop between two sites > Ah I think I see.?Assuming you have no default route learned via eBGP then (given 3 full routing tables, that's probably a fair assumption), the question becomes whether you can intelligently maintain a floating static default based on reachability to the next-hop IP, or if it's better to implement some kind of BGP peering between the two sites. > ? > One possibility might be to consider a conditional static default route - use "ip sla" to test next hop reachability of a provider's router, then use the track command to monitor and apply to?a floating?default route (and of course, you can do this for more than one provider and provide a predetermined sequence of alternate default routes) > ? > I am not personally a fan of iBGP "raw" over a public network (and that's what it would be since the ASNs are the same on both ends),?as most of the protection features?in IOS are focused on eBGP.?GRE tunnel works, though there may be caveats depending on MTU/fragmentation issues and hardware switching support. Maintaining those BGP peers of course assumes that the remote IP in each case is known in one of the active eBGP sessions at all time. Probably a reasonable assumption if you're using provider-owned IPs to peer; maybe less so if you're using IPs that fall within your own larger block. > ? > I may be misunderstanding something about your particular topology, so my apologies if so. > ? > John. > ? > ----------------------------------------------------------------------- From: Randy McAnally [rsm at fast-serv.com] > Sent: Wednesday, September 02, 2009 21:10 > To: Herbert, John; cisco-nsp at puck.nether.net > Subject: RE: [c-nsp] BGP multihop between two sites > > > > I'm not quite clear on the floating default?

In this case, it was routing packets between locations because the prefixes were not in the routing tables.?

If you're extremely rigorous about line-rate, leave four of those ports unused. But the DFC issue is more about Mpps than Mbps. As Phil pointed out, you could run them well under their line-rate, but with small packets, and overwhelm the forwarding capacity of the PFC. -Geoff On Wed, Sep 2, 2009 at 5:59 PM, Ben Steele wrote: > Unless you are hitting a cam limit on any of your resources on your SUP(very > possible if you are exporting netflow) OR you are congesting the crossbar > fabric(sh fabric util) which is pretty unlikely when you are talking a 24G > linecard on a 40G fabric connection then you probably won't see any > difference putting a DFC on a 6724 > > Remember these chassis are a hardware only based forwarding solution, so all > your doing with a DFC is moving cam/asic resources off the sup, so in > regards to your specific questions unless you have filled all your QoS > queues on the sup you are going to see nothing more on the DFC, also the sup > does (from memory) up to 100-200m pps in ipv6, I don't believe for a moment > you are even remotely close to this, and the global ipv6 routing table is no > where near the cam limit for that either, by the way is your SUP an XL? does > the DFC's on the 10G's match the sup or have they fallen back to the lowest > common configuration? > > "...or could it be that DFC's are only really useful to a particular > deployment > and I just *think* i need them? ?;-)" - I think you might be on the money > here. > > If you give us the current utilization of your cam resources(from the sup) > and the 6724 linecard throughput and what its functions > are(netflow/qos/mac/acls etc) then we can tell you for sure. > > Ben > > > On Wed, Sep 2, 2009 at 9:16 PM, Alan Buxey wrote: > >> hi, >> >> okay, from the background of I know what the DFC is and how it >> operates etc... i know I want them - however, I need to justify >> the upgrade/part cost to sort out a couple of 6500's. ?in some of >> our 6500's, the 10G blades have DFCs already...but several 6724's dont >> (they just have CFC). ...as i said, I want them, but need to get >> some management/funding buy-in - and they dont want the 'what it >> does' information - they want some hard and fast facts that Cisco dont >> sem to want to tell me ..... so, the question is >> >> 1) is there any way of showing the sup720 strain/utilisation...particularly >> is there a way of showing DFC usage on the blades where we have them? >> >> 2) it offloads IPv6 and QoS - we're into both of those (and more so over >> the >> next year) - any particular insights into QoS performance/issues without >> DFC ? any throughput figures for IPv6 ? >> >> (i know that with CFC we're limited to the backplane (32mpps?) and we get ~ >> 48mpps >> per blade with DFC) >> >> ...or could it be that DFC's are only really useful to a particular >> deployment >> and I just *think* i need them? ?;-) >> >> alan >> _______________________________________________ >> cisco-nsp mailing list ?cisco-nsp at puck.nether.net >> https://puck.nether.net/mailman/listinfo/cisco-nsp >> archive at http://puck.nether.net/pipermail/cisco-nsp/ >> > _______________________________________________ > cisco-nsp mailing list ?cisco-nsp at puck.nether.net > https://puck.nether.net/mailman/listinfo/cisco-nsp > archive at http://puck.nether.net/pipermail/cisco-nsp/ > From almog.purepeak at gmail.com Thu Sep 3 10:04:51 2009 From: almog.purepeak at gmail.com (almog ohayon) Date: Thu, 3 Sep 2009 17:04:51 +0300 Subject: [c-nsp] CIsco ASA processes Message-ID: <3b53747c0909030704y34c6eeedm6a4284585ba3784c@mail.gmail.com> Hello Everyone,Does anyone knows what is a Dispatch Unit process in Cisco ASA 5510 ??

Otherwise the values are since the last restart. But if your utilisation was steady over all the time, then periodic high volume of logging might have something to do with it. thanks, andrew From gsgranados at comcast.net Thu Sep 3 13:41:07 2009 From: gsgranados at comcast.net (Scott Granados) Date: Thu, 3 Sep 2009 10:41:07 -0700 Subject: [c-nsp] ASA5520 to Pix can't bring up IPSEC L2L tunnel References: <000501ca2b64$54ea36c0$0202fea9@am.thmulti.com><6E21B2BDEF6E714EA0B5BA8D5D0E1401248E269EB4@zy-ex1.zyedge.local> <00ea01ca2bec$cc3c98c0$2208120a@am.thmulti.com> <17838240D9A5544AAA5FF95F8D520316069347A7@ad-exh01.adhost.lan> <012501ca2bf4$ec98c550$2208120a@am.thmulti.com> <17838240D9A5544AAA5FF95F8D520316069347B1@ad-exh01.adhost.lan> <013501ca2bf7$74241a40$2208120a@am.thmulti.com> <17838240D9A5544AAA5FF95F8D520316069347B8@ad-exh01.adhost.lan> Message-ID: <018601ca2cbd$bc8f7600$2208120a@am.thmulti.com> Hi Mike and others, still no love.

I defined each as individual /24's to prevent the inclusion of the 10.18.14.0/24 range and so we can add or delete easily because we're presently migrating a bit from one 10.x range to another. Also, I doubled up the listings 1 for the destination of 10.18.14.0/24 which is the clients and 10.18.15.0/26 which is a far end site. Not sure if I'm heading in the other direction. The error I received while trying to bring up the tunnel is unchanged. "removing peer failed, no match!" I did grab some debug output from the Pix side here's the important bit crypto_isakmp_process_block:src:vpnc, dest:208.x.x.98 spt:500 dpt:500 ISAKMP: reserved not zero on payload 5! ISAKMP: malformed payload I assume malformed payload means I have something set incorrectly during the negotiation phase. Any pointers would be appreciated. I will grab more debug data per the other post but this is what I've tried so far. Thanks Scott ----- Original Message ----- From: "Michael K.

For the nonat rule would I create a sepperate ACL for each target or would a basic acl like I use for the split tunneling do the trick? either access-list ny-vpn extended permit ip 10.18.0.0 255.255.255.0 10.18.15.0 255.255.255.192 or would access-list nonat standard permit 10.18.0.0 255.255.255.0 I have several different targets so how would one define that or is the standard ACL enough?

So, you're remove side is looking for the 10. Addresses, but it's going to see traffic coming from the static outside, NAT'd address. Thus, the tunnel won't come up because your proposals don't match. Mike -- Michael K.

Assuming you have nothing else logging to monitor, you can enable 'logging class vpn monitor debug' and throw up a term mon to gather inbound messages to the ASA from the PIX side. You can gather the information on the PIX with a debug cry isa 2 and then initiate interesting traffic from the ASA using the following, the more valuable information will be on the receiving end. It really doesn't matter which side you enable as the receiver, but I try to stay away from pre 7.x code on the PIXes. packet-tracer input inside icmp 10.1.0.10 8 0 10.18.15.10 detailed Phase: 10 or 11 should be subtype encrypt. If it fails the first time, run it again, the negotiation process causes the first packet to fail as the tunnel is being brought. This type of traffic will also give you your debug information and help you figure out where the failure is. -ryan -----Original Message----- From: cisco-nsp-bounces at puck.nether.net [mailto:cisco-nsp-bounces at puck.nether.net] On Behalf Of Scott Granados Sent: Tuesday, September 01, 2009 8:29 PM To: cisco-nsp at puck.nether.net Subject: [c-nsp] ASA5520 to Pix can't bring up IPSEC L2L tunnel Hi, I have a Pix out in the field and an ASA5520 that I'm trying to configure to pass L2L traffic.

I guess here you're referring to the fact that there is no communication of ingress rates between individual DFCs, or back to the PFC? I posed this question to Cisco at a CPOC lab, and have also heard the same from TAC. Consider the following scenario: Two flows are ingress on a 6500, one on Gi1/0 (where slot 1 has a DFC), and one on Gi2/0 (where slot 2 also has a DFC). They are egress on a third port Gi3/0, which also has a DFC. Since the policing is performed by the ingress LC, if Gi3/0 has a 50Mbps policer, and the flows at Gi1/0 and Gi2/0 are both 40Mbps, neither card will drop any packets, and hence the egress rate at port Gi3/0 is 80Mbps, despite having a 50Mbps policer configured. Unfortunately, I don't have the resources to test this - has anyone tried this scenario, and verified this is _actually_ how things work, rather than theoretically?

For example: Object-group network internal Network-object 10.1.0.0 255.255.0.0 Network-object 10.1.0.0 255.255.0.0 ..... Object-group network ny_nets Network-object 10.18.14.0 255.255.255.0 Then craft your interesting traffic ACL on the ASA to look something like this: Access-list vpn_ny permit ip object-group internal object-group ny_nets Access-list nonat permit ip object-group internal object-group ny_nets Any future changes are done at the object-groups and will be immediately reflected in your interesting traffic ACL and nonat ACL. As Michael has said, the error can be a number of things, I would start with the crypto key though. A lot of the ISAKMP settings (at least in the ASA) are part of the default config and cover just about every common Phase1 setting. From the ASA, issue a 'show cry isa sa detail' and check out the entry that corresponds with your PIX endpoint. Post the results of that once you've got a stream of interesting traffic going from the ASA to the PIX. If possible post the debug results from the PIX to the ASA with the settings that I mentioned earlier, if there is a key mismatch, you'll see that error on the ASA side. In case you're curious, this is the 7.2.4 bug I was referring to as well, it exists through 7.2.4(18): http://tools.cisco.com/Support/BugToolKit/search/getBugDetails.do?method=fetchBugDetails&bugId=CSCsq91271 -ryan -----Original Message----- Scott, Can you provide debugs from the ASA, code versions on both devices and your associated no-nat ACLs? Assuming you have nothing else logging to monitor, you can enable 'logging class vpn monitor debug' and throw up a term mon to gather inbound messages to the ASA from the PIX side. You can gather the information on the PIX with a debug cry isa 2 and then initiate interesting traffic from the ASA using the following, the more valuable information will be on the receiving end. It really doesn't matter which side you enable as the receiver, but I try to stay away from pre 7.x code on the PIXes. packet-tracer input inside icmp 10.1.0.10 8 0 10.18.15.10 detailed Phase: 10 or 11 should be subtype encrypt. If it fails the first time, run it again, the negotiation process causes the first packet to fail as the tunnel is being brought. This type of traffic will also give you your debug information and help you figure out where the failure is. -ryan From gsgranados at comcast.net Thu Sep 3 15:09:12 2009 From: gsgranados at comcast.net (Scott Granados) Date: Thu, 3 Sep 2009 12:09:12 -0700 Subject: [c-nsp] ASA5520 to Pix can't bring up IPSEC L2L tunnel References: <000501ca2b64$54ea36c0$0202fea9@am.thmulti.com><6E21B2BDEF6E714EA0B5BA8D5D0E1401248E269EB4@zy-ex1.zyedge.local> <00ea01ca2bec$cc3c98c0$2208120a@am.thmulti.com> <17838240D9A5544AAA5FF95F8D520316069347A7@ad-exh01.adhost.lan> <012501ca2bf4$ec98c550$2208120a@am.thmulti.com> <17838240D9A5544AAA5FF95F8D520316069347B1@ad-exh01.adhost.lan> <013501ca2bf7$74241a40$2208120a@am.thmulti.com> <17838240D9A5544AAA5FF95F8D520316069347B8@ad-exh01.adhost.lan> <018601ca2cbd$bc8f7600$2208120a@am.thmulti.com> <17838240D9A5544AAA5FF95F8D5203160693486A@ad-exh01.adhost.lan> Message-ID: <01e001ca2cca$0aae9530$2208120a@am.thmulti.com> Ah interesting.

Does this mean the card doesn't work for ADSL-M (Seemingly often branded as SDSL-M) in the UK? We're looking at getting some SDSL-M circuits to see what they're like, from Spitfire and Nildram (Tiscali), anybody using either HWIC-1ADSL-M or C877-M with those providers Annex M services? Anybody using the above products with any Annex-M products in the UK? Any info would be great, as these products are fairly new Google doesn't turn up anything and the Cisco kit is not on the published lists of compatible CPE equipment.

One could simply reference prefix-lists in the BGP config on a per-neighbor basis (or peer-group). The downside to this is that prefix-lists can't haven't inline comments for storing information about the individual prefixes. As the prefixes on the edge grow I would think that admin overhead and potential for errors would grow as well. I could reference route-maps in the BGP config as well (per neighbor/peer-group). I'm doing this today, matching against a prefix-list to get my routes. The upside is I add a new sequence to the route-map per customer and create a uniquely-named prefix-list per customer. This of course requires more config and more potential typos but makes changes as customers come and go much more clearcut (ie, there is no question which prefixes belong to which customer). Another upside is that I can also put specific communities on prefixes with a route-map. I'm not doing this today but I plan to in the future as my BGP community design progresses. A third option is redistributing statics into BGP. This gives me the opportunity to tag specific prefixes and filter them with a route-map so I only redistribute the prefixes that I want redistributed. I can also name static routes. I need a static route anyway to tack up the route for outbound advertisement and to prevent loops. The downside is that I hate using redistribution. I'm not a big fan of it. I've been bit too many times to consider redistribution a good method of doing anything. It will also result in higher CPU load as the RIB is frequently parsed for statics and processed with the route-map if I'm not mistaken. Correct? A fourth option would be to use distribute-lists. I can use remarks to label my individual prefixes in the ACL which is good but I end up with one large distribute-list ACL for all my customer prefixes. That means any errors could affect all customers at once. I also don't end up using route-maps so I don't get to set communities on advertised prefixes. And finally I could use a combination of any of the above to accomplish my goals. What methods do my SP colleagues prefer to use when managing the injection of customer routes into iBGP? I'm open to suggestions. I've tried both of the first 2 options and lean towards the 2nd. It's time I get the remaining customer routes out of the IGP but unfortunately I can't see far enough ahead to decide which method is best. I can't help but to think that there must be a better way to accomplish my goals without increasing my work load too much and without increasing the likelihood of making major mistakes.

Also redistribute static, connected, etc through and use a route-map to set the appropriate communities so something like... ip prefix list not-to-specific seq 5 permit 0.0.0.0/0 le 24 route-map transit1-in permit 10 match ip address prefix-list not-to-specific set community as:666 or for a customer ip prefix-list customera seq 5 permit 192.168.0.0/20 route-map customera-in seq 10 permit match ip address prefix-list customera set community as:115 You can also add in functions here to prepend your AS on a community tag, set local pref, etc. you would need to then just build your community lists so that they know what to do with the various tags (666, no export, 115, announce, etc) for your redistribution do the same match against your prefix list with your CIDR for announcements, against another prefix list which allows for longer prefixes for your internals (tag appropriately) and biggity bam you're set. Tag everything differently for example peering prefixes learned differently from transit and use the route-maps to apply the appropriate tag. This also removes the need for network statements in your BGP section and once in place greatly simplifies and I think in the end creates less room for fat finger errors. With the different tags you will find it very simple to provide customers what ever feed they wish whether it's customers only, customers + peers, customers plus peers + transit, full routes, etc. Thanks Scott ----- Original Message ----- From: "Justin Shore" To: "'Cisco-nsp'" Sent: Thursday, September 03, 2009 12:31 PM Subject: [c-nsp] Options for customer prefix injection into iBGP at the edge > I'm soliciting suggestions on the pros and cons on the assortment of ways > to inject customer routes into iBGP at the edge. > > One could simply reference prefix-lists in the BGP config on a > per-neighbor basis (or peer-group).

But putting that aside, it would be strongly recommended to filter all local routes so you don't receive them from your upstreams. You might also want to confirm that your upstreams are not running JunOS facing you - as I mentioned in the thread (URL) I referenced yesterday, I'm told that by default JunOS appears to 'look ahead' and not send routes that would cause an as-path loop, so your allow-as in wouldn't do anything. I have no idea if that's behavior that can be changed, and I'm happy to be schooled by a JunOS guru on that one if I'm wrong. j.

Assuming you have no default route learned via eBGP then (given 3 full routing tables, that's probably a fair assumption), the question becomes whether you can intelligently maintain a floating static default based on reachability to the next-hop IP, or if it's better to implement some kind of BGP peering between the two sites. > > One possibility might be to consider a conditional static default route - use "ip sla" to test next hop reachability of a provider's router, then use the track command to monitor and apply to a floating default route (and of course, you can do this for more than one provider and provide a predetermined sequence of alternate default routes) > > I am not personally a fan of iBGP "raw" over a public network (and that's what it would be since the ASNs are the same on both ends), as most of the protection features in IOS are focused on eBGP. GRE tunnel works, though there may be caveats depending on MTU/fragmentation issues and hardware switching support. Maintaining those BGP peers of course assumes that the remote IP in each case is known in one of the active eBGP sessions at all time.

As many replies point out, and as many previous threads bear witness to, the current implementations of IOS lack full support for a seperate management VRF. This alone made me curious why people still push in that direction. Generally I assume that some kind of OoB management is best practice already; the typical setup where I'm from is a terminal server of some kind (e.g. Cisco 2512) in each PoP and some octopus cables reaching out to all the console ports. This is for emergencies though, not for "production", i.e. not for Netflow, TACACS+ and so on. A management network in a seperate VRF will not in itself give anyone emergency access to devices. I could imagine obscure software bugs that would actually hinder this access instead. And even though using seperate physical interfaces is much easier with an isolated VRF it is not a prerequisite, and without that some of the arguments for the VRF fall apart IMHO. Seperating non-business traffic (like Netflow, TACACS+, syslog) from business traffic is idealogically a good idea. If you extend this thought we would actually end up with a seperate set of interfaces for _everything_ which is not customer traffic, including IGP and BGP (and LDP for those so inclined). Or am I crossing a line here? And for the record: Yes, poor me, I have no real SP experience, having only worked with enterprise networks.

During the transient CPU spike we saw when we re-inserted compact flash drives into an NPE-G2's or NPE-G1's, BFD complained only on one of the interfaces, as well (as I alluded to in a previous post on this list where the OP was suffering some USB madness). We found it curious that it happened on only one of the links (both are Gig-E off the NPE-G1/2), but for a number of reasons, haven't looked into it any further. Of course, Graceful Restart for IS-IS and LDP was enabled, plus the other link was unaffected, so the data plane didn't hurt.

I'm aware that it's ADSL 2+ underneath but some providers (Spitfire, Nildram) are marketing their ADSL Annex-M products as "SDSL (M)", presumably because of the symmetrical upload/download, and the fact that it sounds like SDSL, which business are already familiar with. > > > We're looking at getting some SDSL-M circuits to see what they're > like, from > > Spitfire and Nildram (Tiscali), anybody using either HWIC-1ADSL-M or > C877-M > > with those providers Annex M services? > > We sell ADSL2+ services in the UK using Be/O2 LLU tails, and they have > "approved" bother the HWIC-1ADSL-M and the C877-M for their service. > I'm using > a C877-M right now. Thanks Simon, I saw mention of the C877-M on the BE UserGroup website but no specific mention of Annex-M products on the (colourful) BE website. Anybody else using Cisco kit at the end of an Annex-M tail from another provider?

I prefer using your second option. Whether in an ISP (with customer routes) or a large enterprise (with lots of business partners), I like the use of prefix-list for the exact reason you stated; labeled by customer/business partner name, route-maps (ditto; labeled by customer/business partner name). This gives you alot of flexibility to tag or influence behavior and policy by altering options within the route-map for both incoming and outgoing routing policies. I think this format also makes it easier on your operations folks since you've named the prefix-lists and route-maps associated with each customer/business partner. -chris > >A third option is redistributing statics into BGP.

( i suppose it's > related to the priority of the queue) They will share, but not equally. Queue 3 will take 75% of the remaining bandwidth, queue 4 will take 25%. If any queue does not use it's allocated amount (either because it uses a shaping SRR instead or because there are no packets) the allocation is simple disregarded. You can view the SRR sharing algo as: 1) take W1 packets from queue 1 (=> 0, shaping) 2) take W2 packets from queue 2 (=> 0, queue empty) 3) take W3 packets from queue 3 (=> 30 if they're there) 4) take W4 packets from queue 4 (=> 10 if they're there) 5) repeat from step 1) So each round of 40 packets takes 30 from Q3 and 10 from Q4. -- Peter From jp at saucer.midcoast.com Fri Sep 4 11:29:48 2009 From: jp at saucer.midcoast.com (jp) Date: Fri, 4 Sep 2009 11:29:48 -0400 Subject: [c-nsp] OT - Dark Fiber In-Reply-To: <48593.1251916052@lavin-llc.com> References: <48593.1251916052@lavin-llc.com> Message-ID: <20090904152948.GA8726@saucer.midcoast.com> We are an ISP and lease fiber from other ISP/CLECs and an independent phone company/CLEC. We have also strung fiber ourselves for short distances with property owner approval. The fiber "owner" has to pay municipal taxes and pole rental fees, and construction can be expensive, so expect to have both MRC and NRC, unless the NRC is amortized into the MRC. The local bell is almost always cost prohibitive or unavailable unless you a re CLEC and then "almost always" changes to "likely". Regarding the topic... If someone provides dark fiber, would they be subject to CALEA requirements to be able to tap and record the transmission? As an ISP, I know the LEAs would come to me rather than the fiber provider, so that has never been a concern to my fiber providers that I know of.

I have a simple router on a stick with a fastethernet interface and multiple 802.1Q subinterfaces connected to a layer 2 switchport in trunk mode. Now say I want to add another switch with the same group of VLANs as the first switch, bridged to the first switch. Instead of connecting the new switch to a trunk port on the existing switch, I'd like to attach it to a router interface. So essentially I want two router interfaces that are transparently bridged, with the ability to attach routed 802.1Q subinterfaces to both interfaces simultaneously. What's the best way to do this?

Not sure if anyone answered this. Check the hello timers for the interfaces. As I recall, ethernet interfaces default to a shorter hello/dead interval than do ATM/frame relay/etc. Longer timer intervals on your ATM interfaces could account for their neighbor relationships being more resilient in the face of adversity.

Turn on IRB in the router. Configure a bridge group for each VLAN. Remove the IP configuration from the dot1q subinterfaces. Add the IP configuration to the BVI for each VLAN. Assign the subinterfaces to the appropriate bridge groups on both physical interfaces. Consider possible spanning tree issues should someone bridge VLANs the two switches accidentally or if you want to intentionally trunk between them for interface redundancy. -- Jay Hennigan - CCIE #7880 - Network Engineering - jay at impulse.net Impulse Internet Service - http://www.impulse.net/ Your local telephone and internet company - 805 884-6323 - WB6RDV From drais at icantclick.org Fri Sep 4 15:40:12 2009 From: drais at icantclick.org (david raistrick) Date: Fri, 4 Sep 2009 15:40:12 -0400 (EDT) Subject: [c-nsp] OT - Dark Fiber In-Reply-To: <20090904152948.GA8726@saucer.midcoast.com> References: <48593.1251916052@lavin-llc.com> <20090904152948.GA8726@saucer.midcoast.com> Message-ID: On Fri, 4 Sep 2009, jp wrote: > Regarding the topic...

As many replies point out, and as many previous threads bear witness to, the current implementations of IOS lack full support for a seperate management VRF. This alone made me curious why people still push in that direction. Generally I assume that some kind of OoB management is best practice already; the typical setup where I'm from is a terminal server of some kind (e.g. Cisco 2512) in each PoP and some octopus cables reaching out to all the console ports. This is for emergencies though, not for "production", i.e. not for Netflow, TACACS+ and so on. A management network in a seperate VRF will not in itself give anyone emergency access to devices. I could imagine obscure software bugs that would actually hinder this access instead. And even though using seperate physical interfaces is much easier with an isolated VRF it is not a prerequisite, and without that some of the arguments for the VRF fall apart IMHO. Seperating non-business traffic (like Netflow, TACACS+, syslog) from business traffic is idealogically a good idea. If you extend this thought we would actually end up with a seperate set of interfaces for _everything_ which is not customer traffic, including IGP and BGP (and LDP for those so inclined). Or am I crossing a line here? And for the record: Yes, poor me, I have no real SP experience, having only worked with enterprise networks.

Especially after the abuses of the last 8 years and probably a lot farther back than that? I've been reading about the requirements and the idea that ISPs cooperate with law enforcement really makes me uneasy on a civil liberties basis. Does Uncle Sam scare tactic people in to compliance? There's just something about making things easier for the NSA and any number of alphabet soup agencies that strikes me as unamerican (to use their own phrase against them) and wrong.

I have to strongly support the out of band management angle. If designed properly you can carry all your management traffic including provisioning and authentication as well as provide emergency access. A simple setup with T1's and 25xx / 26xx boxes with the octopus cables should do the trick. Aggregate them over a reasonable sized geographic area to an aggregation core and Bob's your uncle. When you see DS1 loop pricing in some markets sub $40 per it seems worth it instead of dealing with the headaches and lack of functionality of inband management. ----- Original Message ----- From: "Frank Bulk - iName.com" To: "'Peter Rathlev'" ; "cisco-nsp" Sent: Friday, September 04, 2009 1:05 PM Subject: Re: [c-nsp] Management stuff in VRFs > In short, the best management VRF is a serial-based terminal server. =) > > Frank > > -----Original Message----- > From: cisco-nsp-bounces at puck.nether.net > [mailto:cisco-nsp-bounces at puck.nether.net] On Behalf Of Peter Rathlev > Sent: Thursday, September 03, 2009 4:34 PM > To: cisco-nsp > Subject: Re: [c-nsp] Management stuff in VRFs > > Thank you all for the reponses. > > As many replies point out, and as many previous threads bear witness to, > the current implementations of IOS lack full support for a seperate > management VRF.

Calea was originally to cover the changeover of pstn to digital switches so they can track drug dealers, et al. While it also applies to "broadband" networks, Its not something you are likely to see. You can talk to the (i swear they are nice) CALEA Implementation unit about what you need. They are nice guys and there is no penalty for non-compliance unless you get a lawful request and are unable to comply. Then the FCC gets involved and you could be fined. Your best bet is to actually be social with your local FBI, Secret Service & Police. Tell them who you are, what you do, and when something comes up it wont seem like jackboot thugs :).

We don't get to know much about the subpoenas, but I'd suspect it's a mix of child porn, drunk chatters making death threats online in public forums, etc... I wouldn't be suprised if we someday had to capture traffic for an LEA, so I keep it in mind. I know for certain some of these are from customers with wide open wifi routers. I think it's mostly a scam to make us do more paperwork and for vendors to sell more equipment or upgrades. The vendors were big on this. Encryption is the source of your civil liberty here. The upside is that LEAs are probably supposed to be somewhat more knowledgeable at asking for information in their subpoenas as a result of the existence of a process. Ten years ago, I was talking with a detective in charge of a subpoena I'd been served. I asked him what time zone, and he said Green Mountain Time. I am not joking.

We don't get to know much about the subpoenas, but I'd suspect it's a mix of child porn, drunk chatters making death threats online in public forums, etc... I wouldn't be suprised if we someday had to capture traffic for an LEA, so I keep it in mind. I know for certain some of these are from customers with wide open wifi routers. I think it's mostly a scam to make us do more paperwork and for vendors to sell more equipment or upgrades. The vendors were big on this. Encryption is the source of your civil liberty here. The upside is that LEAs are probably supposed to be somewhat more knowledgeable at asking for information in their subpoenas as a result of the existence of a process. Ten years ago, I was talking with a detective in charge of a subpoena I'd been served. I asked him what time zone, and he said Green Mountain Time. I am not joking.

MARS does take Syslog, SNMP traps, Netflow data, various IDS/IPS alerts and various other inputs ( http://www.cisco.com/en/US/docs/security/security_management/cs-mars/6.0/compatibility/local_controller/dtlc60x.html for the list of supported devices. Pretty much any Cisco product, Extreme routers, Juniper Netscreen/Checkpoint firewalls, etc) MARS is sized based on either events/sec or Netflows per minute. For a busy network, they can scale horizontally by using a Global Controller with multiple aggregators. Good luck.

Not sure if it will cover your requirements, but OpenNMS does a pretty good job with making both SNMP Traps and syslog messages readily available, with lots of filtering possibilities and the likes ... -garry From mtinka at globaltransit.net Sat Sep 5 00:39:31 2009 From: mtinka at globaltransit.net (Mark Tinka) Date: Sat, 5 Sep 2009 12:39:31 +0800 Subject: [c-nsp] Options for customer prefix injection into iBGP at the edge In-Reply-To: <4AA0197E.9010109@justinshore.com> References: <4AA0197E.9010109@justinshore.com> Message-ID: <200909051239.38746.mtinka@globaltransit.net> On Friday 04 September 2009 03:31:10 am Justin Shore wrote: > loops.

We find redistribution useful with l3vpn's, because the NLRI is only limited to the VRF in question. Aside from that, no, we don't like to use it either (although one might argue that Route Leaking in IS-IS is a form of redistribution, between levels). The other place where we've used redistribution is when we need to announce the management IP address of a switch that doesn't support IS-IS through via router it's connected to. But moving on to your issue... > What methods do my SP colleagues prefer to use when > managing the injection of customer routes into iBGP? So there's three kinds of scenarios we typically look at: a) customers who are assigned address space from our allocation. b) customers who have their own allocation but don't run BGP and have us announce it for them. c) customers who have their own allocation and run BGP with us. 1. For customers that use our address space, each router is is assigned a /24 (more or less) from which customers' point-to-point addresses are derived. This is announced as a single route from that edge router. In addition, customers may be assigned additional address space for their LAN, e.t.c., which we announce to the network via: - static pull-up route - BGP network statement (Cisco) - route-filter entry (Juniper) We have a routing policy from each edge router to our route reflectors that sets the LOCAL_PREF and community values as necessary for all our aggregates + longer. This ensures any prefixes that belong to us which we assign to our customers maintain a consistent routing policy. This routing policy references a generic prefix list (Cisco) or route filter (Juniper). 2. For customers who have their own address space but don't run BGP with us, the point-to-point address policy as in 1), above, applies. We also have a routing policy from each edge router to our route reflectors that sets the LOCAL_PREF and community values as necessary for these types of customers. This routing policy also references a generic prefix list (Cisco) or route filter (Juniper). 3. For customers who have their own allocation and run BGP with us, we have a standard outbound policy depending on whether customers want full, partial, customized or default routes. This policy also references a generic prefix list (Cisco) or route filter (Juniper). The inbound policy is either generic for non-kinky, standard eBGP turn-ups, or customized if customers require more specific policies. This policy also references a customized prefix list (Cisco) or route filter (Juniper). These lists are aptly named, making troubleshooting easier for the NOC. In the case of 2), above, admittedly on an on-going operational basis, it is easier to inject customer prefixes into iBGP with Juniper because it's a 2-step process which also achieves filtering, rather than in Cisco where it's a 3-step process with filtering. In Juniper, all you do is: a) write a pull-up static route. b) write a route filter which is referenced by an iBGP export routing policy. In Cisco, you achieve the same with one extra step: a) write a pull-up static route. b) write a prefix list which is reference by an iBGP route map. c) write a 'network' statement in BGP. However, the extra step with Cisco is not a big deal. For the case of 3), above, the Cisco portion is just a two- step process as in the Juniper case (with only a) and b) steps being required), as the customer routes are being generated by, well, the customer. Hope this helps. Cheers, Mark. -------------- next part -------------- A non-text attachment was scrubbed...

I guess the 'network' vs. 'redistribute' is a religious thing, even when it might not have to be :-). Cheers, Mark. -------------- next part -------------- A non-text attachment was scrubbed...

I do have 1 tidbit to share. First an explanation for those that don't know and the list archives. IDSM2 modules have 2 operating modes. Inline and passive. Inline is where you funnel traffic through them by mapping 2 VLANs to them for the inside and outside, sort of like the FWSM (BTW, like the FWSM the IDSM2 is not VRF-aware; using the VLANs is the solution for both LCs). Passive is where you simply use an internal port span to get interesting traffic over to one of the IDSM2's internal ports. IDMS2s ONLY operate in passive mode on 7600s or any other devices running SR. Inline does not work. If you happen running the older SR code that works on both 6500 and 7600s then you SOL. We bought them IDMS2s and 7600s right in them middle of the BU split. Roughly 2.5 years later we're still waiting to get Cisco to take them back (trying to trade for a MARS appliance so it's still a sale for Cisco). We've never used them, never been able to. The product didn't work as advertised. It was a Cisco Advanced Services SME that actually discovered the problem for us. He found the problem acknowledged on an internal Cisco mailing list. Nothing public has ever been said about it to the best of my knowledge. Even if the IDMS2 actually worked in my 7600s I would still recommend a different solution. It can only do 4 contexts. That's not very much in the grand scheme of things. That's not very much throughput for a 40G slot or even a 20G slot. In fact I think it's like the FWSM2 and tops out at 6G. Given the sheer expense of each context, that's not exactly something we can sell to our customers as an upsell service. Personally I would recommend an appliance solution instead of a LC. One of Cisco's appliance based solutions would be fine and cost less. Cisco seems to be driving that way. They EoLed the Anomaly Detector/Guard LCs for the 7600s in favor of the appliance version. I'm sure it's less expensive to produce, requires less interopt with other BUs and can be useful to other customers that don't have/need the larger chassis in that form factor.

Not complying is a felony, not just a simple civil offense. They go after company officers. Try convincing your company officers not to do it; see if they want to take the chance. All SPs were required to officially respond to the FTC with a plan for how they were going to make their network CALEA ready. Not replying was not an option. Politics of the last administration aside, it's not a bad thing that SPs be able to assist law enforcement. Telcos have been required to do so for longer than most people on this list have been alive. As voice traffic moves off the PSTN to the Internet logically CALEA has to follow. Does that mean that the intelligence agencies will follow the letter of the law and not abuse it? Certainly not. The FBI has already shown that they will abuse it with National Security Letters. That will happen under any administration though. Hopefully it will be reduced under the present administration and the process will be tuned and refined. Intelligence agencies (IAs) will always want more data and consumers and their SPs will always want to give up less. The way we help limit the IAs is through the political processes, not through non-compliance. An individual's civil disobedience seldom works. Try non-compliance with the tax man and see how far you get.

So the valid range of subnet masks for this one would be 32 bits down to 29 bits (24,25,26,27-- and so on). Please check out this article https://cisco.hosted.jivesoftware.com/.../How%20do%20prefix%20list%20work.pd f And For question B: A normal access-list CANNOT check the subnet mask of a network. It can only check bits to make sure they match, nothing more. A prefix-list has an advantage over an access-list in that it CAN check BOTH bits and subnet mask - both would have to match for the network to be either permitted or denied. Off course you can use extended access-list to filter route, and make them behave just like a prefix-list, please take a look at the following link http://tcpmag.com/qanda/article.asp?EditorialsID=358 Thanks Victor Cappuccio.- vcappucc at cisco.com CCIE(R/S) #20657 STAC Support Engineer Cisco Small Business Support. -----Original Message----- From: cisco-nsp-bounces at puck.nether.net [mailto:cisco-nsp-bounces at puck.nether.net] On Behalf Of luismi Sent: lunes, 07 de septiembre de 2009 11:17 To: Tomas Caslavsky Cc: ivan.diaz at raxon.es; cisco-nsp at puck.nether.net; Daniska Tomas Subject: Re: [c-nsp] Leaking specific routes from a VRF Hi all, We are doing some tests here with the code provided by Tomas.

Le works like "less than or equal to" So 10.53.0.224/29 le 32 matches any route less than or equal to a /32 inside your /29. So if for example 10.53.0.228/32 arrives it matches, as will 10.53.0.224/30 or 10.53.0.224/29 Without le you match only the /29 so in the above example only the /29 matches. This makes the use of prefix lists very flexible. >b) Is there any difference if we use a normal ACL instead a prefix-list >in the route-map? we also saw several configurations using ACLs and it >seems to do the same. You can use them as well but lose the flexibility.

We would like to be sure that the traffic is routed via the 10G interface as primary and only use the 1G as backup. How is that done, and what is the best choice ?? The normal way of doing this would be to use IGP metrics - set the 1Gb link to have a metric 10 times the 10 Gb link. Unfortunately Cisco has not yet implemented "auto-cost reference-bandwidth" for IS-IS, so you have to set the link metrics manually. Oh yeah, you *really really* want to use IS-IS wide metrics.

On the platform we're using (6500/sup720, 12.2(33)SXI) you don't seem to be able to change the rd of a defined VRF; you have to "no rd" which promptly blows away the "router bgp / address family ipv4 vrf X" as well as the route-target statements; and it won't let you enter a new rd for ~60 seconds, claiming: % Deletion of "rd" in progress; wait for it to complete This is obviously hugely unhelpful for correcting the mistake. Does anyone know if this is possible either without an outage or with a very short one? Or are we stuck with taking the outage?

Or are we stuck with taking the outage? AFAIK there's no way around it. And AFAIK it's not Sup720 specific. With redundant nodes you can of course remove one node from the equation at a time and then change it, but with only one node there's no luck. You could avoid the "deletion in progress" by giving the VRF both a new name and a new RD; this doesn't remove the BGP convergence time though. -- Peter From rsm at fast-serv.com Tue Sep 8 06:40:12 2009 From: rsm at fast-serv.com (Randy McAnally) Date: Tue, 8 Sep 2009 06:40:12 -0400 Subject: [c-nsp] service-policy on virtual interface In-Reply-To: <1252419663.6643.2.camel@abehat.net.rm.dk> References: <4AA6324F.4060504@imperial.ac.uk> <1252419663.6643.2.camel@abehat.net.rm.dk> Message-ID: <20090908103823.M72119@fast-serv.com> Do the same commands work e.g. 'service-policy input/output FooPolicy' at the virtual interface level the same as they do on a physical port, both in and out?

It's more or less clear that each tunnel can receive the necessary bandwidth and that it is consequently subtracted from the overall bandwidth configured for the interface. Therefore there can only be a finite number of TE-tunnels going through an interface. My question is: What will happen if I run a generic IP traffic over this interface in addition to MPLS-TE tunnels? How will this IP flow affect creation of new TE tunnels? What will have higher priority (or what will be dropped/rerouted first) when the interface bandwidth reaches it's max physical capacity? It seems that with an abundance of information about MPLS I can't find neither exact answer to these questions nor the algorithm behind this particular process so any references to white-papers, books, etc are greatly appreciated. Thank you in advance.

You can also prepare any relevant PE-CE routing config in advance. This can be done offline. Then when you want to migrate the customer, you just change the "ip vrf forwarding" command on the customer interface, and make the PE-CE routing work (like wait for the routing protocols to come up). You can do this migration per customer, and you do not have to do it per the whole box, so you can basically control the scope of disruption very easily.

On the platform we're using (6500/sup720, 12.2(33)SXI) you don't seem to be able to change the rd of a defined VRF; you have to "no rd" which promptly blows away the "router bgp / address family ipv4 vrf X" as well as the route-target statements; and it won't let you enter a new rd for ~60 seconds, claiming: % Deletion of "rd" in progress; wait for it to complete This is obviously hugely unhelpful for correcting the mistake. Does anyone know if this is possible either without an outage or with a very short one?

By manipulating the state of a TCP connection, an attacker could force the TCP connection to remain in a long-lived state, possibly indefinitely. If enough TCP connections are forced into a long-lived or indefinite state, resources on a system under attack may be consumed, preventing new TCP connections from being accepted. In some cases, a system reboot may be necessary to recover normal system operation. To exploit these vulnerabilities, an attacker must be able to complete a TCP three-way handshake with a vulnerable system. In addition to these vulnerabilities, Cisco Nexus 5000 devices contain a TCP DoS vulnerability that may result in a system crash. This additional vulnerability was found as a result of testing the TCP state manipulation vulnerabilities. Cisco has released free software updates for download from the Cisco website that address these vulnerabilities. Workarounds that mitigate these vulnerabilities are available. This advisory is posted at: http://www.cisco.com/warp/public/707/cisco-sa-20090908-tcp24.shtml Affected Products ================= Vulnerable Products +------------------ The following Cisco products have a TCP implementation that is affected by these vulnerabilities. Refer to the Software Versions and Fixes section for information on fixed software. Cisco IOS Software To determine the Cisco IOS Software release that is running on a Cisco product, administrators can log into the device and issue the "show version" command to display the system banner. The system banner confirms that the device is running Cisco IOS Software by displaying text similar to "Cisco Internetwork Operating System Software" or "Cisco IOS Software." The image name displays in parentheses, followed by "Version" and the Cisco IOS Software release name. Other Cisco devices do not have the "show version" command or may provide different output. The following example identifies a Cisco product that is running Cisco IOS Software Release 12.3(26) with an installed image name of C2500-IS-L: Router#show version Cisco Internetwork Operating System Software IOS (tm) 2500 Software (C2500-IS-L), Version 12.3(26), RELEASE SOFTWARE (fc2) Technical Support: http://www.cisco.com/techsupport Copyright (c) 1986-2008 by cisco Systems, Inc. Compiled Mon 17-Mar-08 14:39 by dchih The following example identifies a Cisco product that is running Cisco IOS Software Release 12.4(20)T with an installed image name of C1841-ADVENTERPRISEK9-M: Router#show version Cisco IOS Software, 1841 Software (C1841-ADVENTERPRISEK9-M), Version 12.4(20)T, RELEASE SOFTWARE (fc3) Technical Support: http://www.cisco.com/techsupport Copyright (c) 1986-2008 by Cisco Systems, Inc. Compiled Thu 10-Jul-08 20:25 by prod_rel_team Additional information about Cisco IOS Software release naming conventions is available in "White Paper: Cisco IOS Reference Guide" at the following link: http://www.cisco.com/warp/public/620/1.html Cisco IOS-XE Software The version of Cisco IOS-XE Software that is running on a Cisco product can be determined using the "show version" command from the Command Line Interface (CLI). Cisco CatOS Software The version of Cisco CatOS Software that is running on a Cisco product can be determined using the "show version" command from the CLI. Cisco Adaptive Security Appliance (ASA) and Cisco PIX Cisco ASA and Cisco PIX security appliances running versions 7.0, 7.1, 7.2, 8.0, and 8.1 are affected when configured for any of the following features: * SSL VPNs * ASDM Administrative Access * Telnet Access * SSH Access * Cisco Tunneling Control Protocol (cTCP) for Remote Access VPNs * Virtual Telnet * Virtual HTTP * Transport Layer Security (TLS) Proxy for Encrypted Voice Inspection * Cut-Through Proxy for Network Access The version of software that is running on a Cisco ASA and Cisco PIX security appliances can be determined using the "show version" command from the CLI. Cisco NX-OS Software The version of Cisco NX-OS Software that is running on Cisco Nexus 5000 and 7000 series devices can be determined using the "show version" command from the CLI. Scientific Atlanta Products Scientific Atlanta customers are instructed to contact Scientific Atlanta's Technical Support for questions regarding the impact, mitigation and remediation of the vulnerabilities discussed in this document. Contact information for Scientific Atlanta Technical Support can be found at the following web site: http://www.cisco.com/en/US/products/ps10459/serv_group_home.html Linksys Products Customers with Linksys products should contact the following email address for questions regarding the impact, mitigation and remediation of the vulnerabilities discussed in this document: security at linksys.com Products Confirmed Not Vulnerable +-------------------------------- The following Cisco products are not affected: * Cisco IOS XR * Cisco IOS Software Modularity * Cisco ASA and Cisco PIX Software version 8.2 * Cisco PIX Software version 6.x and earlier * Cisco Firewall Services Module (FWSM) * Cisco Multilayer Distribution Switches (MDS) * Cisco Application Control Engine (ACE) Modules and Appliances * Cisco ACE XML Gateway * Cisco Access Control Server (ACS) Solution Engine * Cisco Guard * Cisco Security Monitoring, Analysis, and Response System (CS-MARS) * Cisco ONS 15000 * Cisco Content Services Switches (CSS) * Cisco Wide Area Application Services (WAAS) * Cisco Wireless LAN Controller (WLC) * IronPort C, M, S and X Series Appliances Cisco PSIRT tested Cisco products that are based on Linux and Microsoft Windows operating systems and found that although TCP connections in a FINWAIT1 state may temporarily consume system resources the operating systems eventually clear the TCP connections. If enough system resources are consumed, a sustained DoS condition may be possible. This outcome is highly dependent on the configuration and usage of a system. For more information about how these vulnerabilities affect Microsoft Windows operating systems, please consult the following Microsoft website at the following link: http://go.microsoft.com/fwlink/?LinkId=155978 No other Cisco products are currently known to be affected by these vulnerabilities. Details ======= Multiple Cisco products are affected by DoS vulnerabilities in the TCP protocol. By manipulating the state of TCP connections, an attacker could force a system that is under attack to maintain TCP connections for long periods of time, or indefinitely in some cases. With a sufficient number of open TCP connections, the attacker may be able to cause a system to consume internal buffer and memory resources, resulting in new TCP connections being denied access to a targeted port or an entire system. A system reboot may be required to restore full system functionality. A full TCP three-way handshake is required to exploit these vulnerabilities. Network devices are not directly impacted by TCP state manipulation DoS attacks transiting a device; however, network devices that maintain the state of TCP connections may be impacted. If the attacker can establish enough TCP connections through a transit device that maintains TCP state, device resources may be exhausted and prevent the device from processing new TCP connections, resulting in a DoS condition. If an affected device that forwards traffic (that is, routes) in a network is the target of a TCP state manipulation attack, the attacker could cause a network-impacting DoS condition. Cisco IOS Software All Cisco IOS Software versions are affected by this vulnerability. A device running Cisco IOS Software that is under attack will have numerous hung TCP connections in the FINWAIT1 state. The "show tcp brief" command can be used to display the hung TCP connections. The following is example output showing an attack in progress. Router#show tcp brief | include FIN 63D697C4 192.168.1.10.80 192.168.1.20.38479 FINWAIT1 63032A28 192.168.1.10.80 192.168.1.20.54154 FINWAIT1 645F8068 192.168.1.10.80 192.168.1.20.56287 FINWAIT1 630323F4 192.168.1.10.80 192.168.1.20.6372 FINWAIT1 63D69190 192.168.1.10.80 192.168.1.20.23489 FINWAIT1 The vulnerabilities for Cisco IOS Software are documented in Cisco Bug ID CSCsv04836. Cisco IOS-XE Software All Cisco IOS-XE Software versions are affected by this vulnerability. A device running Cisco IOS-XE Software that is under attack will have numerous hung TCP connections in the FINWAIT1 state. The "show tcp brief" command can be used to display the hung TCP connections. The following is example output showing an attack in progress.

Cisco ASA and Cisco PIX Software All Cisco ASA and Cisco PIX Software versions are affected by these vulnerabilities. A device running Cisco ASA and Cisco PIX Software that is under attack will have numerous TCP connections in the established state. The "show asp table socket" command can be used to display the TCP connections. The following is example output showing a potential attack in progress. FIREWALL# show asp table socket | grep ESTAB TCP 123a8a6c 192.168.1.10:80 192.168.1.20:46181 ESTAB TCP 123e6d54 192.168.1.10:80 192.168.1.20:29546 ESTAB TCP 1244f78c 192.168.1.10:80 192.168.1.20:40271 ESTAB TCP 124f8d2c 192.168.1.10:80 192.168.1.20:46599 ESTAB TCP 12507f2c 192.168.1.10:80 192.168.1.20:5607 ESTAB It is possible for normal traffic to cause established TCP connections to appear on Cisco ASA or PIX devices, especially VPN connections terminated to the device. In order to confirm if established TCP connections are part of an attack, administrators should use a monitoring point outside the firewall such as a packet sniffer or Netflow collection agent to examine the profile of the suspicious TCP connections and determine if an attack is occurring. Note: The show asp table socket command was introduced in Cisco ASA and Cisco PIX Software 8.0(1). Further detail about hung TCP connections can be found with "show conn detail all long" command. The IP address used to qualify the example below is the address of the firewall interface under attack. FIREWALL# show conn detail all long | grep 192.168.1.10 TCP outside:192.168.1.20/62345 (192.168.1.20/62345) NP Identity Ifc:192.168.1.10/80 (192.168.1.10/80), flags UB, idle 0s, uptime 0s, timeout 1m0s, bytes 0 TCP outside:192.168.1.20/56268 (192.168.1.20/56268) NP Identity Ifc:192.168.1.10/80 (192.168.1.10/80), flags UB, idle 0s, uptime 0s, timeout 1m0s, bytes 0 TCP outside:192.168.1.20/63445 (192.168.1.20/63445) NP Identity Ifc:192.168.1.10/80 (192.168.1.10/80), flags UB, idle 0s, uptime 0s, timeout 1m0s, bytes 0 TCP outside:192.168.1.20/49151 (192.168.1.20/49151) NP Identity Ifc:192.168.1.10/80 (192.168.1.10/80), flags UB, idle 0s, uptime 0s, timeout 1m0s, bytes 0 TCP outside:192.168.1.20/57147 (192.168.1.20/57147) NP Identity Ifc:192.168.1.10/80 (192.168.1.10/80), flags UB, idle 0s, uptime 0s, timeout 1m0s, bytes 0 Note: Both troubleshooting commands referenced about will display TCP connections that are terminated to a firewall interface and transiting through the firewall. The vulnerabilities for Cisco ASA and Cisco PIX Software are documented in Cisco Bug ID CSCsv02768. Cisco NX-OS Software All Cisco Nexus 5000 and 7000 platforms running Cisco NX-OS Software are affected by these vulnerabilities. A Nexus 5005 or 7000 device running Cisco NX-OS Software that is under attack will have numerous hung TCP connections in the FIN_WAIT_1 state. The "show tcp connection detail" command can be used to display the hung TCP connections. The following is example output showing an attack in progress. NEXUS# show tcp connection detail | include FIN State: FIN_WAIT_1 State: FIN_WAIT_1 State: FIN_WAIT_1 State: FIN_WAIT_1 State: FIN_WAIT_1 The hung TCP connection vulnerabilities for Nexus 5000 and Nexus 7000 devices are documented in Cisco Bug ID CSCsv08325 and Cisco Bug ID CSCsv08579 respectively. While investigating the TCP state manipulation vulnerabilities, it was discovered that Cisco NX-OS on Nexus 5000 platforms may be vulnerable to a system crash when receiving a specific sequence of TCP packets. This vulnerability is documented in Cisco Bug ID CSCsv08059 and has been assigned CVE identifier CVE-2009-0627. The TCP state manipulation vulnerabilities have been assigned Common Vulnerabilities and Exposures (CVE) identifier CVE-2008-4609. Vulnerability Scoring Details ============================= Cisco has provided scores for the vulnerabilities in this advisory based on the Common Vulnerability Scoring System (CVSS). The CVSS scoring in this Security Advisory is done in accordance with CVSS version 2.0. CVSS is a standards-based scoring method that conveys vulnerability severity and helps determine urgency and priority of response. Cisco has provided a base and temporal score. Customers can then compute environmental scores to assist in determining the impact of the vulnerability in individual networks. Cisco has provided an FAQ to answer additional questions regarding CVSS at: http://www.cisco.com/web/about/security/intelligence/cvss-qandas.html Cisco has also provided a CVSS calculator to help compute the environmental impact for individual networks at: http://intellishield.cisco.com/security/alertmanager/cvss CSCsv04836 - Connections getting stuck at FINWAIT1 state CVSS Base Score - 7.8 Access Vector - Network Access Complexity - Low Authentication - None Confidentiality Impact - None Integrity Impact - None Availability Impact - Complete CVSS Temporal Score - 6.4 Exploitability - Functional Remediation Level - Official-Fix Report Confidence - Confirmed CSCsv07712 - Connections getting stuck at FINWAIT1 state CVSS Base Score - 7.8 Access Vector - Network Access Complexity - Low Authentication - None Confidentiality Impact - None Integrity Impact - None Availability Impact - Complete CVSS Temporal Score - 6.4 Exploitability - Functional Remediation Level - Official-Fix Report Confidence - Confirmed CSCsv66169 - TCP Connections get stuck in FINWAIT1 state CVSS Base Score - 7.8 Access Vector - Network Access Complexity - Low Authentication - None Confidentiality Impact - None Integrity Impact - None Availability Impact - Complete CVSS Temporal Score - 6.4 Exploitability - Functional Remediation Level - Official-Fix Report Confidence - Confirmed CSCsv02768 - TCP connections getting stuck in FINWAIT1 state CVSS Base Score - 7.8 Access Vector - Network Access Complexity - Low Authentication - None Confidentiality Impact - None Integrity Impact - None Availability Impact - Complete CVSS Temporal Score - 6.4 Exploitability - Functional Remediation Level - Official-Fix Report Confidence - Confirmed CSCsv08325 - TCP connections may get stuck in any state after ESTAB indefinitely CVSS Base Score - 7.8 Access Vector - Network Access Complexity - Low Authentication - None Confidentiality Impact - None Integrity Impact - None Availability Impact - Complete CVSS Temporal Score - 6.4 Exploitability - Functional Remediation Level - Official-Fix Report Confidence - Confirmed CSCsv08579 - TCP connections get stuck in FINWAIT1 state indefinitely CVSS Base Score - 7.8 Access Vector - Network Access Complexity - Low Authentication - None Confidentiality Impact - None Integrity Impact - None Availability Impact - Complete CVSS Temporal Score - 6.4 Exploitability - Functional Remediation Level - Official-Fix Report Confidence - Confirmed CSCsv08059 - NEXUS 5000 crashes after certain TCP packets CVSS Base Score - 7.8 Access Vector - Network Access Complexity - Low Authentication - None Confidentiality Impact - None Integrity Impact - None Availability Impact - Complete CVSS Temporal Score - 6.4 Exploitability - Functional Remediation Level - Official-Fix Report Confidence - Confirmed Impact ====== Successful exploitation of the TCP state manipulation vulnerabilities may result in a DoS condition where new TCP connections are not accepted on an affected system. Repeated exploitation may result in a sustained DoS condition. A reboot may be required to recover affected systems. In addition, Cisco Nexus 5000 systems may crash upon receiving a specific sequence of TCP packets. Software Versions and Fixes =========================== When considering software upgrades, also consult: http://www.cisco.com/go/psirt and any subsequent advisories to determine exposure and a complete upgrade solution. In all cases, customers should exercise caution to be certain the devices to be upgraded contain sufficient memory and that current hardware and software configurations will continue to be supported properly by the new release. If the information is not clear, contact the Cisco Technical Assistance Center (TAC) or your contracted maintenance provider for assistance. Cisco IOS Software Each row of the Cisco IOS software table (below) names a Cisco IOS release train. If a given release train is vulnerable, then the earliest possible releases that contain the fix (along with the anticipated date of availability for each, if applicable) are listed in the "First Fixed Release" column of the table. The "Recommended Release" column indicates the releases which have fixes for all the published vulnerabilities at the time of this Advisory. A device running a release in the given train that is earlier than the release in a specific column (less than the First Fixed Release) is known to be vulnerable. Cisco recommends upgrading to a release equal to or later than the release in the "Recommended Releases" column of the table. +-----------------------------------------+ | Major | Availability of Repaired | | Release | Releases | |------------+----------------------------| | Affected | First Fixed | Recommended | | 12.0-Based | Release | Release | | Releases | | | |------------+--------------+-------------| | | Vulnerable;

Cisco IOS Software The Cisco Guide to Harden Cisco IOS Devices provides examples of many useful techniques to mitigate against the TCP state manipulation vulnerabilities. These include: * Infrastructure Access Control Lists (iACL) * Receive Access Control Lists (rACL) * Transit Access Control Lists (tACL) * VTY Access Control Lists * Control Plane Policing (CoPP) * Control Plane Protection (CPPr) * Management Plane Policing (MPP) For more information on the topics listed above, consult the Cisco Guide to Harden Cisco IOS Devices at the following link: http://www.cisco.com/en/US/tech/tk648/tk361/technologies_tech_note09186a0080120f48.shtml Cisco CatOS Software Cisco CatOS software provides VLAN Access Control Lists (VACL) to mitigate against the TCP state manipulation vulnerabilities. For more information on configuring VACLs on CatOS 7.x software versions, please consult the following link: http://www.cisco.com/en/US/docs/switches/lan/catalyst6500/catos/7.x/configuration/guide/acc_list.html For more information on configuring VACLs on CatOS 8.x software versions, please consult the following link: http://www.cisco.com/en/US/docs/switches/lan/catalyst6500/catos/8.x/configuration/guide/acc_list.html Cisco ASA and Cisco PIX Software Cisco ASA and Cisco PIX Software provide a method to expire stalled half-closed TCP connections that helps mitigate against the TCP state manipulation vulnerabilities. This method protects against attacks directed to a firewall and devices protected by a firewall. The "timeout half-closed" command will expire TCP sessions that have remained in a half-closed state beyond a user-configured timeout. FIREWALL(config)# timeout half-closed 0:5:0 This command will set the TCP half-closed timeout to the smallest permitted value of five minutes. For more information on the TCP half-closed timeout, please consult the following link: http://www.cisco.com/en/US/docs/security/asa/asa80/command/reference/t.html#wp1500148 Cisco Nexus Software Cisco Nexus software provides several ACL methods to mitigate against the TCP state manipulation vulnerabilities. For more information on configuring ACLs on Nexus 5000 systems, please consult the following link: http://www.cisco.com/en/US/docs/switches/datacenter/nexus5000/sw/configuration/guide/cli_rel_4_0_1a/sec_ipacls.html For more information on configuring ACLs on Nexus 7000 systems, please consult the following link: http://www.cisco.com/en/US/docs/switches/datacenter/sw/4_1/nx-os/security/configuration/guide/sec_nx-os-cfg.html Cisco Applied Mitigation Bulletin Additional mitigations that can be deployed on Cisco devices within the network are available in the Cisco Applied Mitigation Bulletin companion document for this advisory, which is available at the following link: http://www.cisco.com/warp/public/707/cisco-amb-20090908-tcp24.shtml Obtaining Fixed Software ======================== Cisco has released free software updates that address these vulnerabilities.

In other words if you run regular IP traffic, it will not be subject to RSVP reservations and will not be used in calculations, so if you overload the link with it, the tunnels will still stay up. Just like you can overload the link by sending all kinds of traffic through the tunnels (that do not automatically adjust), but bandwidth that you reserve will be less than what you are sending out. And set up and holding priority is what you can use to keep the tunnels where they are, but unless bandwidth is reserved the mechanism does not know about its use.

Reading some stuff on RSVP would be great too, but it will put anyone to sleep.

It's more or less clear that each tunnel can receive the necessary bandwidth and that it is consequently subtracted from the overall bandwidth configured for the interface. Therefore there can only be a finite number of TE-tunnels going through an interface. My question is: What will happen if I run a generic IP traffic over this interface in addition to MPLS-TE tunnels? How will this IP flow affect creation of new TE tunnels? What will have higher priority (or what will be dropped/rerouted first) when the interface bandwidth reaches it's max physical capacity? It seems that with an abundance of information about MPLS I can't find neither exact answer to these questions nor the algorithm behind this particular process so any references to white-papers, books, etc are greatly appreciated. Thank you in advance.

Main driver is a SQL database, so there will be a bunch of SQL servers virtualized using VMware, running against a SAN over iSCSI. I've done some research and it looks like I can build the network using a Catalyst 4900M or a Nexus 5010, at about the same cost. I am familiar with the Catalyst family, but have no experience with the Nexus. At this point, the only major difference I see is that Nexus supports Fibre Channel (which I don't need). For being different product families, I am having a hard time understanding what the major differences are. Can anyone enlighten me? If anyone has hands-on experience with both and willing to share, that would be most appreciated.

Main driver is a SQL database, so there will be a bunch of SQL servers virtualized using VMware, running against a SAN over iSCSI. I've done some research and it looks like I can build the network using a Catalyst 4900M or a Nexus 5010, at about the same cost. I am familiar with the Catalyst family, but have no experience with the Nexus. At this point, the only major difference I see is that Nexus supports Fibre Channel (which I don't need). For being different product families, I am having a hard time understanding what the major differences are. Can anyone enlighten me? If anyone has hands-on experience with both and willing to share, that would be most appreciated.

The top bridge is connecting local ethernet to ethernet over ATM over whatever, so it's a glorified DSL modem; the bottom bridge is there to clean the traffic that would otherwise flood to the exchange (e.g. to eliminate other weird, foreign-sourced frames that seem to appear from the telco layer-2 service from time to time). For IPv4, this all works gloriously. For IPv6, not at all. The bridges are both cisco 2600 devices with "no ip routing". Some config fragments below. The top bridge has a DSL WIC and I'm bridging between that and a VLAN configured on an FE port; the bottom bridge has a pair of FE ports, and I'm bridging between them with no VLANs. There is a single BVI configured on "cisco bridge 2" just to give me an address to ssh to. I tried removing that and managing the box via the console, but no change. Is there something fundamental I'm missing, here? Why should a transparent bridge behave differently with IPv4 than it does with IPv6?

If possible, you might want to try removing that statement (if you're local to the device, of course) to see if that does it. I don't think there is a 'bridge 1 route ipv6'.

The main difference (AFAIK) is that in a route reflector setup, your RR will reflect all the different routes as long as all the PEs use different RDs. This in turn means that each RR client (PE) will need more memory to hold all possible prefixes, but on the other hand they will be able to use one of the alternative paths immediately upon discovering that the current best path is invalid, e.g. by the BGP next hop for the current best path disappearing from the IGP. With the same RD on all PEs your route reflector will only reflect the current best path. When this invalidates you have to wait for the RR to select a new best path and update the RR clients. In the mean time traffic is black-holed. So basically: Faster convergence in a route reflector setup. -- Peter From td_miles at yahoo.com Tue Sep 8 20:02:51 2009 From: td_miles at yahoo.com (Tony) Date: Tue, 8 Sep 2009 17:02:51 -0700 (PDT) Subject: [c-nsp] service-policy on virtual interface In-Reply-To: <20090908112733.M18911@fast-serv.com> Message-ID: <452396.77085.qm@web110108.mail.gq1.yahoo.com> Hi Randy, I remember the previous topic because I was the one who suggested that you disable QOS globally (if you didn't need it) when you were seeing throughput issues. I stand by this as the easiest solution at the time, but now that you need to use QOS for something else, you'll have to look at the queueing and work out what is happening and how to fix it. If you don't classify any of your traffic the it will all be in the default class (ie. DSCP & COS = 0) and go into the queue for this class. What happens depends on what hardware you have. As an example, if you have a 6516-GE-TX card then the following happens you enable QOS. If you run the command "show queueing int gigx/y" you will see something like this: Default COS is 0 Queueing Mode In Tx direction: mode-cos Transmit queues [type = 1p2q2t]: Queue Id Scheduling Num of thresholds ----------------------------------------- 1 WRR low 2 2 WRR high 2 3 Priority 1 WRR bandwidth ratios: 100[queue 1] 255[queue 2] queue-limit ratios: 70[queue 1] 15[queue 2] 15[Pri Queue]*same as Q2 queue random-detect-min-thresholds ---------------------------------- 1 40[1] 70[2] 2 40[1] 70[2] queue random-detect-max-thresholds ---------------------------------- 1 70[1] 100[2] 2 70[1] 100[2] queue thresh cos-map --------------------------------------- 1 1 0 1 1 2 2 3 2 1 4 6 2 2 7 3 1 5 From this we can see: Number of queues = 3 (2 normal/configurable + 1 priority) Number of thresholds per queue = 2 thresholds (except PQ, which has just 1) You can see from the COS-MAP (or maybe you can't) that COS 0 & 1 are assigned to queue 1, threshold 1. The real problem is the random-detect thresholds on the queue. What this means is that once the queue gets full above the min-threshold the box will start random throwing out packets (based on queue weightings and number of packets in queues). When the queue gets above max-threshold then all packets for this queue with the COS value will be dropped. This is done to ensure there is some space in the queues for higher priority packets. From the card above you can see that unclassified traffic (COS 0) will start getting discarded at 40% and as the queue gets fuller it will progressively discard more. If the queue gets to 70% then ALL COS0 traffic will be discarded. In queue 1 this 30% at the top of the queue is for COS 2 & 3 packets in threshold 2. This theoretically means that the maximum throughput you would see on the above card with just enabling QOS and not configuring anything is around 700Mbps (70% of 1Gbps). in reality it would probably be a bit less, but that would be absolute maximum You can change this behaviour with the commands: wrr-queue random-detect min-threshold wrr-queue random-detect max-threshold (you'll have to read the syntax for the commands, you need to put queue and thresholds on them) I'm using this card as an example because I have one in a box I can play with, you'll need to adjust it for your particular situation. All of the above is for TX queues, you may also have to adjust the RX queues. Now you can see why I previously said the easier option was just to disable QOS ;) regards, Tony. --- On Tue, 8/9/09, Randy McAnally wrote: > From: Randy McAnally > Subject: Re: [c-nsp] service-policy on virtual interface > To: "Randy McAnally" , "Ian MacKinnon" , "cisco-nsp at puck.nether.net" > Received: Tuesday, 8 September, 2009, 9:29 PM > Thanks, I don't want to enable global > QOS (queuing) which 'mls qos' will > enable.

The difference between Nexus and an normal Catalyst is the nexus is an cut-though switch where the catalyst is an store-and forward. we use Nexus for backup service. I can recommend using Nexus, it works fine, and it's fastere. The interface is a bit different but not much.

For example, Nexus supports vPC, which means that you have a multi-chassis EtherChannel trunk from a pair of Nexus 5000/7000 distribution switches to any EtherChannel enabled access switch. This basically doubles the Access->Distribution bandwidth as you have no links blocked by Spanning Tree. Another major difference is the integration of Nexus 2000 Fabric Extenders with Nexus 5000 switches. The Nexus 2000 switches basically act as remote (over 10Gig fiber) "linecards" of the Nexus 5000. This allows deploying top of the rack switches without the additional management overhead: http://www.cisco.com/en/US/products/ps10110/index.html Hope this helps.

The Nexus seems to recompile the ACL after each line there are work arounds vs have the acl upload completely and recompile once. 3) Nexus STP is RSTP not pvst+ 4) The TACACS implimentation of this platform seems incomplete. TACACS is useable, but local-admin accounts must be configured and used for configuration. 5) The layout of the configuration is different (as someone mentioned) Features must be enabled (ie., ospf,tacacs must be enabled by using 'feature ???') if ospf feature is not enabled, it can't be used until it's enabled (not configured). OSPF is configured mostly under the interface (passive-interface, process # vs globally) HSRP is configured like an interface where you enable the hsrp #, then you are in a config-hsrp# mode where you then finish the hsrp config. HSRP is not just configured under "router(conf-if)#" 6) QoS you specify the queueing structure (ie., 1P2q4T) and not the queueing or scheduling or thresholds. Obviously there is the ability to tweak the QoS, but the base config viewing is much simpler 7) Obviously there are many hardware differences (Resilient Sups which are better than the dual-sup on the 6500), transfering the configuration from a 6500 to a 7K (ie., replacing a 6500 with a 7K) is pretty challenging. Think of it from going from CatOS to CATIOS and having to create a script to migrate your config (trunk, vrf) to the 7K. Just some thoughts...

It does - packet-sampled control of flow creation (i.e., true sampled NetFlow), logical OR of TCP flags within a flow, dropped traffic, layer-2 NetFlow across ports within the same VLAN, larger NetFlow table size, etc. ACL construction is much easier than on 6500 (doesn't have the weird LOU constraints), and you get per-interface uRPF mode settings, as well (vs. whole-box on 6500). ----------------------------------------------------------------------- Roland Dobbins // Sorry, sometimes I mistake your existential crises for technical insights. -- xkcd #625 From rsm at fast-serv.com Wed Sep 9 08:17:37 2009 From: rsm at fast-serv.com (Randy McAnally) Date: Wed, 9 Sep 2009 08:17:37 -0400 Subject: [c-nsp] service-policy on virtual interface In-Reply-To: <452396.77085.qm@web110108.mail.gq1.yahoo.com> References: <20090908112733.M18911@fast-serv.com> <452396.77085.qm@web110108.mail.gq1.yahoo.com> Message-ID: <20090909121511.M91209@fast-serv.com> Thank Tony.

ACLs as entered in a "config terminal" session are applied to hardware the moment you hit enter on an individual line - yes. the system is smart enough to do 'inline' ACL processing if you have an ACL that makes appropriate use of sequence numbers in it. if you're just wholesale uploading a replacement ACL in bulk, then suggest you use "configure session" where you can ask the system to 'verify' the ACL will fit in CL-TCAM resources then 'apply' it. using configure sessions would not 'tax' it or iteratively recompute it on every new ACL line you enter. see ACLs are always committed in an atomic manner on N7K provided you have CL-TCAM resources to do so. > > 3) Nexus STP is RSTP not pvst+ N7Ks STP is PVRST(+) or MST - same as what you would have on a Catalyst platform. the only thing that isn't there (intentionally) is the ability to configure N7K as a legacy 802.1D STP - although as dictated by the standards, N7K can talk legacy 802.1D to legacy bridges - but you cannot intentionally configure it to behave in that legacy manner. this is actually a good thing. :) > 4) The TACACS implimentation of this platform seems incomplete. > TACACS is useable, but local-admin accounts must be configured and > used > for configuration. this isn't quite true. RBAC (roles based access control) is applied to all management access, whether you're managing via CLI, SNMP or Netconf/XML. this is a divergence from the historic IOS 'priv level 15' / "enable" type mechanisms but there is no reason why you cannot assign a RBAC role from an AAA server whether that be via TACACS+ or RADIUS. by default, a priv-level of 15 from an AAA server maps a user to the predefined RBAC role of network-admin or vdc-admin automatically. alternatively you can have the AAA server provide the relevant AV-Pair to provide the RBAC role(s) a given user is in. the documentation chapter on AAA on cisco.com provides the details for all of the above. see > > 5) The layout of the configuration is different (as someone mentioned) > Features must be enabled (ie., ospf,tacacs must be enabled by using > 'feature ???') if ospf feature is not enabled, it can't be used > until it's > enabled (not configured). yep - thats intentional. services are 'conditional' on NX-OS. until you enable the 'feature' the process for that feature is not running, consuming RAM or even part of the CLI parser chain. > OSPF is configured mostly under the interface (passive-interface, > process # vs globally) there is the historic way of doing it too, if you wish to (e.g. 'network' statements globally) - but the general feedback has been that interface-centric is more intuitive for many things. > 6) QoS you specify the queueing structure (ie., 1P2q4T) and not the > queueing or > scheduling or thresholds.

By all means have a go on your 3750 it can't hurt you any, but it won't be a direct translation from anything you get working on 3750 to 6500. I'd recommend you have a look at Chapter 2 of the Cisco "Enterprise QoS Solution Reference Network Design Guide" (particularly the section on 6500 QoS, starts at 2-77): http://www.cisco.com/univercd/cc/td/doc/solution/esm/qossrnd.pdf Also have a read of the QoS section of 12.2SXH Software Configu Guide: http://www.cisco.com/en/US/docs/switches/lan/catalyst6500/ios/12.2SX/configuration/guide/qos.html Both are very dry, but have a lot of information in them as well as some relevant examples. Read, try and then ask more questions on the list if you get stuck ! regards, Tony. __________________________________________________________________________________ Get more done like never before with Yahoo!7 Mail.

It might hold true in a test environment where you only had two interfaces and you pushed traffic in one and out the other. If I had access to the gear to test this I would like to and see what happens with and without QoS enabled. In most normal environments you would probably have bursty traffic and over subscription somewhere even if it the egress interface wasn't being over-utilised (ie average egress <1000Mbps). There are also buffer limits that are applied to the queues. The below is from the output of "show queueing int gigx/y": queue-limit ratios: 70[queue 1] 15[queue 2] 15[Pri Queue] The above output says that queue 1 (ie. default class, COS 0) is only allowed 70% of the buffers. I'm not sure whether the "queue-limit" is a hard limit though (ie. it can't ever be exceeded). I'm not totally convinced of this part of my argument myself. It a 1:1 situation, do the queues fill at all or can the egress interface transmit as fast an ingress packets so that there is no queueing at all (as you questioned above) ? You then have the ratio of how the queues are serviced, which is: WRR bandwidth ratios: 100[queue 1] 255[queue 2] So queue 1 gets 100/(100+255) = 28% of the WRR scheduler and queue 2 gets 72%. Even though queue 2 is smaller, because it gets serviced with a higher weighting it will empty quicker than queue 1. There is also the previous thread from the OP who stated that with default QoS enabled he was only getting ~400Mbps out of his Gbps port. http://puck.nether.net/pipermail/cisco-nsp/2009-July/062100.html This suggests that stuff is being dropped to make sure the queue buffers aren't filled so that there is room for any stuff with higher COS settings perhaps ? If the queue was filled with COS 0 traffic and some higher COS traffic comes along you would have to drop the higher COS traffic due to lack of space in buffers which kind of defeats the purpose of QoS (give/reserve priority to higher preferenced traffic). I would point to the below reference on not enabling QOS globally without looking at your traffic because you may get less performance than with QoS disabled: http://www.cisco.com/en/US/docs/switches/lan/catalyst6500/ios/12.2SX/configuration/guide/qos.html#wp1750716 This next link also has some examples of how changing some of the queue values affects what happens to the traffic in the queues. http://www.cisco.com/en/US/products/hw/switches/ps700/products_tech_note09186a008015bf98.shtml If someone else wants to correct me then please do. This is how I understand it works, but I'm happy for it to be otherwise. I'm aware that this stuff gets archived and people will be looking at it in the future, I don't want someting that is incorrect to be left around for people to be looking at thinking it is correct (peer reviewed == good). Anyone more knowledgable on the subject wish to chime in ? regards, Tony. __________________________________________________________________________________ Get more done like never before with Yahoo!7 Mail.

The 70% WTD doesn't prevent the interface from carrying 1 Gbps. > Queueing should only be occurring when the (instantaneous) packet > arrival rate exceeds the rate at which the device can dispatch the > packets, and as those queues get to various thresholds of %-full, > they'll execute WRR to manage the queue depth, correct? I think you mean RED instead of WRR, but yes. This means that even an interface with no buffers could throw out full line rate if the traffic arrives correctly. It is of course still a problem to have a default WTD of 70% for CoS/DSCP 0 traffic, which in OPs case is all traffic. The switch is cannot handle bursts as well and you waste 30% of the expensive RAM used for buffering. Depending on burstiness of traffic this might or might not be a problem. But for most practical purposes, enabling QoS and adjusting the first WTD for the default queue (typically queue 1) up to 100% should give the same results as no QoS. -- Peter From avayner at cisco.com Wed Sep 9 11:09:15 2009 From: avayner at cisco.com (Arie Vayner (avayner)) Date: Wed, 9 Sep 2009 17:09:15 +0200 Subject: [c-nsp] Tracking a dynamic default - supported?

Seriously: I'm not exactly sure what the actual impact is. What we're going to do is: - identify what parts of IOS use TCP (telnet, ssh, rsh, bgp, ldp, http/s, ftp, others?) (for some weird reason, "show ip sockets" only shows UDP sockets on our boxes, and "show tcp brief" only shows ESTABLISHED TCP sessions - how can I see what TCP LISTEN sockets are there??) - find out what the impact is on each ("fill all available slots, lock out legitimate admins" or "fill all available memory, killing the box") - find out how to mitigate - telnet/ssh -> vty ACLs - rsh -> recent IOSes send RST to unknown peers - bgp -> takes care of itself (doesn't talk to unknown peers) - http/https -> turn off - ldp -> ?? - ftp -> ?? - generic -> receive ACLs ("if the platform happens to support it"), infrastructure ACLs ("not always effective in catching all possible IP addresses that a box with many customer /30 or /29s might have") gert -- USENET is *not* the non-clickable part of WWW! //www.muc.de/~gert/ Gert Doering - Munich, Germany gert at greenie.muc.de fax: +49-89-35655025 gert at net.informatik.tu-muenchen.de -------------- next part -------------- A non-text attachment was scrubbed...

What is the real risk ? > > http://www.cisco.com/warp/public/707/cisco-sa-20090908-tcp24.shtml If I'm reading the notes correctly, to exploit the problem the attacker must be able to complete a TCP 3-way handshake. That would imply that the attackers packets can either get through iACLs or that there are no ACLs in place. This will mainly affect those people with unsecured TCP-based services such as telnet, SSH, RSH, SCP, HTTP, and HTTPS. Routers providing WebVPN services are at risk and need to be upgraded to fix the problem since disabling WebVPN is probably not an option. Other TCP services like BGP and LDP shouldn't be affected unless one of your configured neighbors is going to exploit the vulnerability. If you can't trust your own equipment or your peers to not exploit vulnerabilities on your equipment.... So the hundreds of thousands of "under-managed" IOS devices out there that have the default config with TCP services like HTTP and telnet enabled are going to suffer. All the more reason for Cisco to change the default configuration to default to having all services disabled out of the box. Make the admin turn on features themselves that compromise their security. No reason to compromise their security for them. Fixing this would require implementing security basics such as creating a VTY ACL, creating a HTTP/HTTPS ACL or disabling it altogether if it's not used, implementing CoPP, iACLs, etc. Usual stuff. It looks like I'll be doing a round of upgrades in November. It's time anyway.

In a Cisco Security Advisory that we published last year (http://www.cisco.com/warp/public/707/cisco-sa-20080924-sip.shtml), we wrote the following: 'Different versions of Cisco IOS have different ways of verifying whether the Cisco IOS device is listening for SIP messages. The "show ip sockets", "show udp", "show tcp brief all", and "show control-plane host open-ports" commands can be used to determine this, although not all of these commands work on all IOS releases. Since it is not practical in this document to provide a list of commands corresponding to the various releases, users should try the aforementioned commands to determine which ones work for their device.' The problem is that historically we've had different internal APIs that applications and services can use to register the ports they need to open. I believe "show control-plane host open-ports" is the latest incarnation and the desired way moving forward but not all applications and services have migrated to it which is why we still rely on different commands.

Thanks for that insight. It doesn't *really* enlighten me, unfortunately. The "show control-plane host open-ports" command is not available on 12.2S, 12.3 main, 12.4 main or 12.2SXF/SXH/SXI up to SXI2. None of the other commands reliably display *TCP* listening sockets.

For one, this state of affairs puts us (the Cisco PSIRT) in a difficult situation when we write our Security Advisories since we don't have a simple, single way to tell our customers how to check if their devices are affected by whatever vulnerability we are disclosing. > > (and I can't really see why "how is the service registering for a given > TCP port internally" should have any effect on "display ports registered > for services", people are known to have written programs that query > multiple data sources and present the result in a concise format...) I am not privy to the details but I think it's been a matter of re-writing the existing show commands to use data from multiple data sources, or moving everybody to a single API and use a single source; it seems like the latter is what has been chosen.

Some of the ports are really only open from certain source IPs (like telnet/ssh if a vty ACL is used), so when nmap doesn't list anything, you never know "is *this* address not permitted to see the telnet port?" or "is the telnet service really not listening at all?" For the things that I know about (telnet, ssh, http/s, ldp, bgp) I know how to verify, but I was hoping for an easy way to see what else might be lurking... gert -- USENET is *not* the non-clickable part of WWW! //www.muc.de/~gert/ Gert Doering - Munich, Germany gert at greenie.muc.de fax: +49-89-35655025 gert at net.informatik.tu-muenchen.de -------------- next part -------------- A non-text attachment was scrubbed...

Worked around the issue by configuring "bandwidth 10000000" on the SVI. And on that same subject, does anyone know when Cisco is going to fix all the hard-coded 10G limitations on this platform? You can't configure anything above 10G, no interface bandwidths, no rsvp bandwidths, no lsp reservations, nothing.

Are you sure the two sups are identical hardware, or could the bottom one have too little memory installed for the (presumably common) IOS image? Does "sh bootvar" indicate any differences between the two? There's nothing about RPR+ that should cause the behaviour you describe in normal operation.

It's also worth emphasising that JunOS has a consistent cross-platform API for configuring their devices, and has done for a long while now. Cisco's (embryonic) efforts seem to be falling firmly into the "one XML schema per device, but you can tunnel them all over netconf!" I am not amused.

I remember my cisco account manager in 1998 telling me that mainline IOS12 would be fully modular. W00h00! Cisco is a very large company and it appears to have a lot of empires. Multiple empires beget balkanisation and lead to the sort of software train splits that we see. I can imagine that it must be very difficult to keep any sort of control on source code, when you have all sorts of groups with all sorts of different product lines, different requirements and different time-scales. Problem is, forking your code is like scrambling your egg. Very easy to do, and it can even taste nice. Unscrambling is not so easy, though. The problem brings to mind something that Vijay Gill from Google said* recently about software development, albeit in a slightly different context: "you require an insane amount of force of will". If it's even possible to maintain some form of control over the IOS code base (and realistically, I don't know if it is, given the diversity of the product set), insane force of will would be required.

To be fair, JUNOS has its share of warts here. They split up namespaces by JUNOS revision. Since the XML namespace is considered as part of the name of the tag, this means that though they have consistent schemata, their tags are named differently between versions. Getting some XML handling tools to go through the gyrations to look for "junos-interface" and not "junos93:junos-interface" and "junos94:junos-interface" has been difficult for me - especially when it's clear that they are the same kind of thing. It's especially annoying when the new version introduces no new sematics. I don't honestly have any idea what the right approach is. I've heard rumors that JUNOS is moving away from versioned tags in v10 or 11, but I don't know if I should believe that. -- Ross Vandegrift ross at kallisti.us "If the fight gets hot, the songs get hotter.

I've done a fair bit of work with JUNOS' XML interface (in netconf, commit scripts, op scripts, etc), and I've got to say I've never seen that issue before. I'm not aware of any requirement to use any version specific tags. The biggest problem I have is handling different configs when there really is a change between versions, that is how to take advantage of new features when possible, when not every router has been upgraded to the new code yet. But yes JUNOS certainly has its share of warts. They are going through growing pains as they expand outside their traditional core router space and try to become like Cisco. Unfortunately the end result is that they are becoming like Cisco. And while they still have some of the most advanced technology and smartest people out there, they also have a large number of idiots mucking things up, and the number seems to go up every day. Still though, netconf has never crashed my router when I tried to use it, which is more than I can say for IOS. :) -- Richard A Steenbergen http://www.e-gerbil.net/ras GPG Key ID: 0xF8B12CBC (7535 7F59 8204 ED1F CC1C 53AF 4C41 5ECA F8B1 2CBC) From ray at oneunified.net Fri Sep 11 14:12:22 2009 From: ray at oneunified.net (Ray Burkholder) Date: Fri, 11 Sep 2009 15:12:22 -0300 Subject: [c-nsp] eigrp over atom Message-ID: <009001ca330b$6918cbd0$3b4a6370$@net> I'm having problems getting eigrp to talk over an mpls l2 link between two cpe devices. cpe -- 3550 -- 7206 -- 7206 -- 3560 -- cpe cpe - 3550: access port on 3550 3550 - 7206: trunked port on vlan 100 7206 - 7206: mpls l2 xconnect 7206 - 3560: trunked port on vlan 100 3560 - cpe: access port on 3560 I'm connecting two sites via pseudowires.

One thing that might be 7600/6500 specific on this matter is that we have been seeing multiple crashes on both primary and secondary supervisors when changing elements such as this on this platform running 12.2SR/12.2SX code. We've figured the safest way is to configure this in parallel, then try and clean up every line of VRF configuration relating to the old VRF. We've seen crashes where there's memory corruption and the primary supervisor crashes. Or where the line-by-line sync to the secondary in SSO causes it to crash. Both are triggered by trying to remove the VRF RD and reconfigure it. TAC haven't been able to reproduce either, so unfortunately we've got no bug ID.

This, however, is quite difficult to use, for me. I've never been able to really find what I'm looking for, while navigating it. I've found working with TAC and saving my bug ID's with notification way easier :-). Cheers, Mark. -------------- next part -------------- A non-text attachment was scrubbed...

When analyzing 2 or 3 possible version yeilds 4,000+ hits per version it becomes an excercise in camping out for several days of reading. But what really aggrevates me is when you speak of these frustrations to the account team they try to sell you Advanced Services.

IIRC the last time I tried to use Cisco Works (a couple of years back) there was a feature to check for Bugs in all IOSes used in a network managed by Cisco Works. It always returned 0 Bugs. I used Wireshark to troubleshoot this and found out that CW was always trying to reach a specific website and the server returned a 404. I know some people who would rely on the message by CW and who would feel perfectly save.

Many thanks to one folk who contacted me privately after Google'ing their way to this thread: Frequent kernel panics have been experienced on all versions of Mac OS X 10.5 (Leopard) with VMware Fusion 2 and the Cisco VPN Client installed. Workaround 1: disable IPv6 on Mac when working with the VPN on a system that has VMware Fusion installed. Workaround 2: uninstall VMware Fusion (may not be feasible for most). Workaround 3: run the VPN inside VMware Fusion (doesn't protect traffic generated inside Mac OS X). Cisco are aware about the problem, and said they won't fix the it since the Cisco VPN Client and virtual environments is unsupported (whatever that means). Suffice it to say, AFAIK, the Cisco VPN Client doesn't support IPv6. Bug ID CSCsj38286 was filed for this case. Details as below: ===== unity mac fails with parallels fusion and crossover Symptoms Parallels, Fusion, and CrossOver prevent the VPN Client from working properly. Conditions The VPN Client does not support the use of virtual environments. Workarounds Cisco VPN with Parallels: * Install the VPN Client SW on MacOS. * Configure Paralllels Networking. You'll probably want to use "shared networking" in Parallels. This causes Parallels to share a single MacOSX-side IP address by using NAT on all network traffic to/from the guest virtual machines/OS's. Some applications (IPTV) are NAT-intolerant and won't work in this case. Alternately, instead of running Cisco VPN Client on MacOS, it can be run on the Windows side. Of course, then MacOSX would not be 'inside' the VPN but Windows would be. ===== Since Cisco don't plan to do anything about this, I'll have a chat with VMware and see what they say (considering it's clear that the Cisco VPN Client kernel extension is the one that crashes the system). My private messenger also had this interesting bit to add: "Also, worth nothing is that the "Local LAN access" feature in Cisco VPN client is IPv4 only. Which means that an attacker could access your computer over IPv6 and then be able to enter your company's network over the VPN connection from your machine. I've pointed that out too and Cisco hid behind the 'IPv6 is not supported' excuse." Perhaps I can bug my account team, again :-). Hope this is useful for some. PS: I'm now running Snow Leopard (10.6.1). No crashes due to this, thus far, but who knows... Cheers, Mark. -------------- next part -------------- A non-text attachment was scrubbed...

I'm having an issue with a Cisco IPSec/VPN connection that won't seem to shake. I connect to a 2811 Cisco router configured with the EazyVPN infrastructure, using Cisco's VPN Client for Mac OS X 10.6.1 (the latest Cisco VPN client for Mac, 4.9.01.0180). The router is running 12.4(24)T1 (using the "T" train to support SSL/VPN's) When I connect to the VPN server, all is well. But it's guaranteed that after just about 10 minutes or so, DNS queries no longer work. The VPN would still be up, and I can connect to hosts via their IP address. DNS just bums out. The workaround is to disconnect from the VPN server, and reconnect it. Of course, this isn't much of a solution, considering my IP address changes and I have re-establish some of my sessions to things. I'm seeing the same issue on my Windows XP Professional home PC as well, so I can't chalk it down to Mac. Suffice it to say, I've had this problem since I started using Mac, i.e., since Tiger. Anyone else seeing this? I'm using public IP addresses off the VPN server, so no NAT is going on. The DNS servers are sitting off the public network at the remote end of the VPN; changing them around hasn't yielded much. The problem persists whether I connect to the VPN server over UDP or TCP. All help appreciated. Cheers, Mark. -------------- next part -------------- A non-text attachment was scrubbed...

Doesn't offer traditional web based SSL services or posture assessment, but does allow you to support 64bit OS'es. Cost is around $500 list for the 5550 and less for smaller platforms as I recall... MUCH cheaper than the old Anyconnect SSL license. Only problem is you must run 8.2, and its not quite there for us yet, but we will be testing an interim release soon.

Cisco does not manage software in a way that features and capabilities go to every platform/release. Each platform runs its own release-ops team, with the rare exception of 'mainline'. The platform specific trains eg: S/SX etc pick up mainline features via bulk syncs of code. I've been asking for this capability for years, there is no way this is going to show up. Cisco does not have the fortitude to keep a platform from shipping to pick up a central-eng/nsstg(itd) driven cleanup. If something impairs the ability for cisco to recognize revenue, such as security/PSIRT issues it's unlikely to stop things from shipping. ie: You need to ask your account team to prioritize these over you actually buying a device. If it stops them from being able to sell you routers, it will get fixed. If not, it's unlikely to have an impact. While you're at it, ask for protected memory in the software. It's not like ram/flash are expensive these days... - Jared From jason at lixfeld.ca Mon Sep 14 09:16:06 2009 From: jason at lixfeld.ca (Jason Lixfeld) Date: Mon, 14 Sep 2009 09:16:06 -0400 Subject: [c-nsp] 12.2(18)SXD to 12.2(33)SRB|C|D Message-ID: As I look through the release notes, I thought I'd also ask here to see if anyone here has experience upgrading between these two versions on a 7600.

The machine is a 7600 series router, running Cisco IOS Software, c7600rsp72043_rp Software (c7600rsp72043_rp-ADVIPSERVICES-M), Version 12.2(33)SRC1, RELEASE SOFTWARE (fc1) Any ideea if this is a known BUG, and if there is some command on the IOS that forces you to add a new neighbor to a peer-group?
