Keeping the PW with L2 > on 3750ME will make your customer happier. ... we're in a situation where extending MPLS into the access may make a bit of sense. The platform currently in the field is as described in this thread, the Cisco 3750ME, albeit it's working in Layer 2- only mode, today. In the spirit of not wanting to replace these boxes with something else more capable as yet, do the comments from Rubens, above, still hold true as of IOS 12.2(52)SE? Keeping in mind the various hardware/software restrictions associated with this class of platforms, we'd be looking to run the following on the system (some are advertised as supported by Cisco, others are implied as such): * MPLS upstream to the core * IPv4 forwarding for customers * IPv4 forwarding over MPLS (upstream to core) * IPv6 forwarding for customers * IPv4, IPv6, MPLS ECMP * Locally-significant VLAN's for customers * EoMPLS for customers * l3vpn's for customers (BGP-based) * IS-IS (Loopbacks + Infrastructure) * BGP (default route importation only) Since all our Layer 2 features are used to "wire" customers to the nearest Layer 3/MPLS-capable box, we have no need to implement Layer 2 features beyond local VLAN support, provided the ones mentioned above can work without issue. We haven't had a chance to run anything as remotely advanced as the features highlighted above, so any useful operational feedback (especially the negatives) from folk who have would be much appreciated, as we begin our own tests as well. Operator feedback in this case is initially far more useful than input from Cisco themselves. The 3750ME really only makes sense if those features can be reliably supported beyond paper; else, the case for Layer 2-only Ethernet switches becomes far more compelling, e.g., Cisco 2960, e.t.c.

It appears that because of the network statements, the supernet routes (/18s, /19s, etc) are being distributed via BGP to the rest of the network which is by design(I assume). This doesn't seem ideal because if traffic is sent to an IP address that doesn't have a more specific route than say /18, or /19 it travels all the way through the network to the edge before stopping. I might be blowing the impact of this out of proportion, but it just seems like a waste of resources.

You could always tag these hold-down routes with a community, then when someone sends a packet to them, the next-hop could be rewritten to a local discard/null0 instance.

References: Message-ID: <013901ca8d81$4694e0a0$2408120a@am.thmulti.com> Drew, network statements are for the weak.:) (I'm kidding of course) but there is a better way. You should use community tagging in combination with prefix lists and route maps. The idea is that you announce routes according to a tag and the behavior of the announcements depends on the specific tag applied. For example, you could tag routes as peers, transits, global announce, etc and formulate the type of feeds you give your customers by filtering against communities so a customer wants peers and customers only you could match the two appropriate community tags. This also allows you to tag the communities you globally announce uniquely and make the announcements in a unified way at your edges. If you accompany this method with the appropriate redistribute static, redistribute connected, etc and use route maps to control this behavior you can remove the need for network statements completely and greatly decrease the things you need to modify and as a result the possible mistakes. The other upside here is you can mark your more specifics as do not export and better control traffic internally better directing the traffic in your example. It also allows you to accept communities from your customers and have automatic actions taken based on the tags they apply. Let me know if you need some configuration examples. ----- Original Message ----- From: "Drew Weaver" To: "Cisco-nsp" Sent: Monday, January 04, 2010 12:35 PM Subject: [c-nsp] BGP - Announcing routes to Internet providers. > Howdy, > > I am trying to figure out if there is a different/newer/better(?) way to > announce our public IP ranges to our Internet providers, currently we are > declaring our subnets in 'network statements' in the BGP configuration, we > have static routes setup like ip route x.x.x.x 255.255.224.0 Null0 254 and > then we have a extended access-list applied to each peer with our net > blocks listed in them. > > It appears that because of the network statements, the supernet routes > (/18s, /19s, etc) are being distributed via BGP to the rest of the network > which is by design(I assume).

This is a message from the RFC, but I would assume it has something to do with the PPP/L2TP negotiation between the LAC and LNS, and the LAC not agreeing to something sent from the LNS...

Several new features have been added ( see list below ) nfdump-1.6 is mostly compatible with nfdump-1.5.x. nfdump-1.6 works with current NfSen 1.3.2, however, the new features are not accessible using the interface. *** Please note: *** PortTracker from NfSen 1.3.2 does *NOT* work with nfdump-1.6. An updated version for NfSen/PortTracker will be released later. - Peter NEW in 1.6 since 1.5.8 ( latest on top ) - ---------------------- o Add router IP extension. o Add router ID extension (engine type/ID) o Add srcmask and dstmask aggregation o Aggregated ( -a, -A, -b, -B ) or sorted flows ( -m ) can be written back to binary files ( -w ) Note: This results in a behaviour change for -w in combination with aggregation o Extend -N ( do not scale numbers ) to all text output not just summary o Remove header lines of -s stat, when using -q ( quiet ) Note: This results in a behaviour change for -N o Remove legacy v1.4 file compatibility o Remove -S option from nfdump ( legacy 1.4 compatibility ) o Make use of log (syslog) functions for nfprofile. o Move log functions to util.c o Update sflow collector. o Add parse_csv.pl script as an example to parse csv output o Add csv output format ( -o cvs ) as replacement for -o pipe - keep -o pipe for now. o Flow-tools converter updated - supports all common elements. o Sflow collector updated. Supports more common elements. o Add sampling to nfdump. Sampling is automatically recognised in undocumented v5 header fields and in v9 option templates. see nfcapd(1) o Add @include option for filter to include more filter files. o Add bidirectional aggregation ( -b, -B ) - experimental feature o Add flexible aggregation comparable to Flexible Netflow (FNF) over all available v9 tags o All new tags can be selected in -o fmt:... see nfdump(1) o topN stat for all new tags is implemented o Integrate developer code to read from pcap files into stable branch o Update filter syntax for new tags o Add flexible storage option for nfcapd. To save disk space, the data extensions to be stored in the data file are user selectable. o Added more v9 tags for netflow v9. The detailed tags are listed in nfcapd(1) Beside of MAC addresses and VLAN labels, also MPLS labels and many more v9 tags are now supported. AS numbers and interface numbers are now 32bit clean. Adding new tags also extended the binary file format with data block type 2, which is extension based. File format for version <= 1.5.* ( Data block format type 1 ) is read transparently. ( --enable-compat15 ) Data block type 2 are skipped by nfdump 1.5.8. o Added option for multiple netflow stream to same port. -n Example: -n router1,192.168.100.1,/var/nfdump/router1 So multiple -n options may be given at the command line Old style syntax still works for compatibility, ( -I .. -l ... ) but then only one source is supported. o Move to automake for building nfdump o Make nfdump fully 64bit compliant. ( 32/64bit data alignments and access ) Compiles and runs cleanly on 32/64bit systems o Switch scaling factor ( k, M, G ) from 1024 to 1000. - -- _______ SWITCH - The Swiss Education and Research Network ______ Peter Haag, Security Engineer, Member of SWITCH CERT PGP fingerprint: D9 31 D5 83 03 95 68 BA FB 84 CA 94 AB FC 5D D7 SWITCH, Werdstrasse 2, P.O.

You need to have an IP that you will assign to the dial-in user. (Unless you intend to use this as a bridge, which I don't know if XP will support). You should define some local pool of IP(s) that you will hand out. eg: ip local pool mypool 192.168.0.1 192.168.0.2 interface Group-Async1 ip unnumbered FastEthernet0/0 ip tcp header-compression passive ip pim border encapsulation ppp no ip mroute-cache async default routing async mode interactive peer default ip address pool mypool no fair-queue no cdp enable ppp max-bad-auth 3 ppp authentication pap chap group-range 1 This is taken from an old archive of configs that I have from doing dial in the good-old-days...

Let's back a step and ask the questions we should have been asking in the first place: * Are you an end-user or a Service Provider (somewhat reliable answer could be gleaned from Drew's e-mail address)? * What's the size of your network? * How many uplinks do you have? * How far apart are your uplinks? If it turns out Drew's uplinks are close together, all the beautiful design ideas presented here are a huge overkill.

I hope you all had a good holiday break. Does anyone know for sure what the Ethertype is for the CLNS packets? I've found a couple IEFT drafts that talk about it it to a degree: http://tools.ietf.org/html/draft-ietf-isis-ext-eth-01 http://tools.ietf.org/html/draft-ietf-isis-ext-eth-01 They imply that for packet sizes under 1500 that CLNS uses the standard IEEE 802.3 ethertypes. The drafts specifically address packets over 1500 bytes though. One suggests 0x8872 and the other suggests 0x8870. I can't find anything definitive though. I'm trying to think what all could affect the Ethertype for IS-IS. MPLS won't. LAGs might (I can't find anything about Ethertype for PAgP or LACP either). Nothing else comes to mind though. Can anyone tell me for sure what the Ethertype is on IS-IS packets?

It will not get very far, though, so it's questionable whether it will leak over to upstream1 and influence the return traffic coming from upstream1. Outbound traffic: policy routing seems to be the quickest (and the dirtiest ;) solution. Getting it to work if the exit points are too far apart is a nightmare. If you're OK with the /28 being very tightly bound to the specific uplink (i.e. no connectivity when the uplink is down), there are a few MPLS VPN tricks you could use.

I assumed it was only released "for" a specific version of the 3550-24 because that's the only model left of the 3550 family that's not reached EOL. I saw that it would boot on a 3550-48, but didn't go any further with it than watching it boot. What goes wrong with it? > any reason for lurking down in the 12.1EA release train? Have you looked at the difference in RAM usage between 12.1EA and 12.2SE?

This is a way to keep customer prefixes in iBGP instead of your IGP. Your actual global announcements can be tagged with communities when generated (either by redistribution, or network statements with route-maps) to be matched by per-eBGP peer route-maps to influence (prepend, block, allow, change MED, tag with provider community) their behavior. This provides more control over your actual global announcements, and provides much more information regarding your actual customer prefixes as Scott stated when announcing to peers or other customers, especially if you publish a BGP community document for them to reference. (See extremely long NANOG thread from Oct/Nov regarding upstream community support) Regarding Drew's initial question -- unless you are seeing significant enough traffic to your unassigned address space to cause actual congestion or network issues, there really isn't a performance problem. If it is, the suggestion of setting next-hop for your static hold-down routes to an IP that is routed to Null0 on all your edge routers (192.0.2.1 is what I commonly see listed in remote-blackholing documents) would cause the traffic to be dropped at the ingress edge instead of transiting the network would cause the traffic to be dropped at the ingress edge instead of crossing your network from ingress to where the annoucement is sourced. -- Brandon Ewing (nicotine at warningg.com) -------------- next part -------------- A non-text attachment was scrubbed...

Each VRF has a physical interface uplinking to the global table and a default pointing out of that interface. The global table uplinks to the rest of the network and carries a full BGP view. All three tables have an OSPF instance. I'm trying to move these routes out of OSPF into iBGP, and IOS seems intent on foiling me. 1) There doesn't appear to be any BGP way to get a VRF route into the global table as an IPv4 route. This makes some sense, as that's basically asking to redistribute between address families - which doesn't make any sense in most cases. 2) I've tried redistributing from a VRF OSPF instance into ipv4 BGP, but IOS says no: lab-6506.dc3(config)#router bgp 65000 lab-6506.dc3(config-router)#redistribute ospf 2 %VRF specified does not match this router lab-6506.dc3(config-router)#redistribute ospf 2 vrf shared %VRF specified does not match this router Similar for other cross-VRF redistributions. 3) I've lab'd a config where I move everything into a VRF from the global table, and then use PE-CEish eBGP to get the routes to the rest of the network. This works, but the AS_PATH is wrong. I could use as-override to fix this, but that isn't supported on the 6500 core routers. 4) I tried to come up with a way to get the global table's OSPF instance cut down appropriately, but most of the LSAs are type 5 since we redistribute static routes. This prevents the goal of getting the routes out of OSPF. 5) Manually duplicate every VRF static/connected route in the global table and just do the usual redistribution of statics. This seems like a very difficult config to keep in sync - about 3k prefixes with occasional additions or updates. But it does actually work. Have I missed any options? #5 seems like the only thing that has any hope of being correct, but man, that's a pain. I might be able to live with #3, but I need to make sure that all of our tools will live with the incorrect AS_PATH.

BGP requires that all routes be leaked between VRFs, since the BGP routes need to be matching types of NLRIs - a route from a VRF has a different SAFI than an IPv4 route from the global table. If there is a way to do this without duplicating the static routes as in your third link above, I'd love to know about it! If I move the global table into a VRF, I then have the problem that I can't fix the AS path since my platform doesn't support as-override. > To take somewhat intelligent approach I suggest to read about the > "Common services VRF" in?"MPLS and VPN Architectures" -?~?Ivan > Pepelnjak,?Jim Guichard - a great set of books not only about > MPLS. That's the weird thing about this installation - there is no MPLS or VPN here. No interfaces even have MPLS enabled. I'm strictly using the multi-VRF CE functionality to provide separate routing tables. This is installation should really be solved with a virtual router, but it's stuck on IOS for the time being and the VRFs do the job nicely.

Yep that's the key - it just hit me that if I run two OSPF processes in the global table. Use one just for redistribution of routes into iBGP and use the other for my actual IGP.

Question - can you use 'neighbor allowas-in' instead of as-override? I'm not sure why your BGP AS-PATH was wrong in scenario #3 above - but I'm using that in a very similar scenario in my lab to solve the problem of having the same eBGP AS used at 2 different sites connected to 2 different PE routers.

You could filter against a prefix list for something like ip prefix-list not-to-specific seq 5 permit 0.0.0.0/0 le X where X depends on how finely you wish to filter. In most full feeds you'd take a /24 or shorter but in your case you can't do this do to memory concerns. You could try /20 or shorter, /19 etc until you meet your memory requirements. Simply by filtering shorter than /24 you'll gain a lot of milage. Of course your ability to control outbound traffic deteriorates the more heavily you filter but them's the breaks when memory is a concern. On the inbound side with a single /24 you won't have a lot of flexability. You'll hit issues for example if upstream carriers filter shorter than /24 and only pick up your provider's parent block. If your upstreams have good community options you can control announcments of your block a bit more. For example, in the case of XO you can trigger prepends to specific major peers allowing you to pad say AS 701 more heavily but leave other networks untouched. Depends on what knobs your carrier gives you to twittle. There's also local pref but that's non transative. ----- Original Message ----- From: "Vincent C Jones" To: "Jason Shearer" Cc: Sent: Wednesday, January 06, 2010 11:57 AM Subject: Re: [c-nsp] Cisco 2801 full bgp multihome > One trick I've used where resources are tight is to "take" full routes, > but filter them so that I only accept "local" (short AS path) and a few > key indicator prefixes (typically out of country root DNS server > subnets).

I was wondering if anyone knows how and if it's possible to terminate frame lines on a cisco, either a 7200 or 6500 without a frame switch. I followed the example here, http://www.ciscopress.com/articles/article.asp?p=170741 &seqNum=7 but this will not work for me as it assumes you have 2 different frame-relay circuits on two different t1 ports. I'm using a PA MC T# canrd and I also tried creating sub interfaces off the t1 channel, but when I use the frame-relay route command I gives me an error that both DLCIs are on the same interface L. All I'm trying to do is terminate a frame-relay on a cisco without a frame-relay switch. if this possible could someone give me an example or point me in that direction. thanks! paul From gsgranados at comcast.net Wed Jan 6 15:36:26 2010 From: gsgranados at comcast.net (Scott Granados) Date: Wed, 6 Jan 2010 12:36:26 -0800 Subject: [c-nsp] Cisco 2801 full bgp multihome References: <"a01aa eac1001060835o1bdc31fdt9c4a0306bd986427"@mail.gmail.com> <1262807859.17745.29.camel@X61.NetworkingUnlimited.nul> <019001ca8f0d$c3839dd0$2408120a@am.thmulti.com> <1262809919.17745.37.camel@X61.NetworkingUnlimited.nul> Message-ID: <01ae01ca8f0f$f1fd9650$2408120a@am.thmulti.com> Right, which is why you'd need your floating default statics and why you should tag internal prefixes differently. Tagging customer routes with one community say and your learned transit routes as another is a good idea. Your internal more specifics could be tagged and marked no-export so you're able to engineer as needed inside your network. ----- Original Message ----- From: "Vincent C Jones" To: "Scott Granados" Cc: "Jason Shearer" ; Sent: Wednesday, January 06, 2010 12:31 PM Subject: Re: [c-nsp] Cisco 2801 full bgp multihome Scott, Careful... filtering on prefix length will block the very "local" prefixes you are probably most interested in--the prefixes of the upstreams' other customers who may be advertising a /24 not in that upstream's address space.

I'm currently using 12.2(50)SE3 on a 3550-12T and the only difficulties that I have run into is a high ( >90% cpu load when total throughput on the load-balanced links reaches 200 Mbps ). I am curious to find out if the high cpu load is caused by some incompatibility between 12.2(50)SE3 and the 3550-12T (since the version is not officially supported on the platform). However, this bug (no load sharing after reload) is making me think twice about testing 12.2(46)SE6. On the other hand, the bug fix for this issue could be the reason for the high cpu load .... Out of curiosity, is anybody here using a 3550 to route more than 200Mbps ( at about 40,000 packets per second forwarding rate ), I would be interested in comparing cpu loads with or without load-sharing.

After lots of googling, I read much controversy about what is supposed to work and what not, both in terms of hardware, as well as software versions. From my understanding, I am running a IOS which is supposed to be supported. Before I upgraded (old IOS), the WIC-1ADSL cards was not detected. Now, both cards are detected, but I still do not have any ATM interfaces available.

What SSH server software does this? I was going to state that in all recent versions of OpenSSH (at least on FreeBSD) one could change: #UseDNS yes ...to: UseDNS no ...in the /etc/ssh/sshd_config file. Even though I've never done this change before, I have notified others that the option is available. My whole-hearted recommendation would be to configure forward and rDNS for all hosts attempting to connect to the box. IPv6 inclusive. Otherwise, the huge disheartening lag time is a non-subtle reminder that the connecting host's DNS is fscked up. If you are connecting from within RFC1918 space, it's internal, so fix it. If it's v6, fix it, or contact your ISP to fix it (if you are an SSH client trying to reach an SSH server on a remote network as an IPv6 client, in today's early v6 day-and-age, you *will* be able to find an engineer that is v6-clueful). If it is an IPv6 DNS resolution issue with your ISP-assigned addresses, I will pretty much guarantee that they will be interested to learn about the problem. They already have v6 deployed, and nobody has done so yet without wanting and desiring feedback. If you feel that I am wrong in the statements regarding IPv6, contact me privately. It very well could be that the SSH server is trying to do a reverse lookup on a residential client of an ISP that doesn't configure any rDNS for its resi IP blocks whatsoever. In this case, contact your ISP, and ask if they can at least generate automated reverse entries for their known 'dynamic' blocks. If they say no, ask why. If you get nothing, ask for a static IP with an rDNS entry (some ISPs will only assign statics at the /29 boundary. In cases of rDNS requirement, it may be worth paying for it). Port 113/TCP has nothing to do with this imho. This is a DNS issue that can be resolved by the IP address supplier of the client, or at worst, be fixed at server application level as specified above. I'm starting to feel the dpi/hijacking anger sensation for some reason. Perhaps someone will eventually create a global qinq (or its technological equivalent) specifically for the revitalization of what the Internet was meant to be ;) ...can we get back into ACL/firewall discussion now, I was thoroughly enjoying what Roland has been saying.

Rancid, Netbrain, or the other tool of your choice. One note: if you have a 7200 router, the SN that the router will report is NOT the one you want - you want a number that starts with a 7, and is on a sticky label on the back of the router.? To the best of my knowledge there isn't a way to pull that from the router remotely if you didn't add it in (using snmp-server chassis-id or the like).?

The topic came up on NANOG several times in the past. I seem to recall someone saying that they used outside air as well since they were in very high latitudes.

That may or may not be an issue depending on your location. I don't have the article handy, but I recall Google mentioning that they can just "turn off" and redistribute load to other datacenters if one gets too hot. ~Seth From oles at ovh.net Thu Jan 7 13:59:28 2010 From: oles at ovh.net (oles at ovh.net) Date: Thu, 7 Jan 2010 19:59:28 +0100 Subject: [c-nsp] Data Center cooling In-Reply-To: <17838240D9A5544AAA5FF95F8D520316074E7EE9@ad-exh01.adhost.lan> References: <17838240D9A5544AAA5FF95F8D520316074E7EE9@ad-exh01.adhost.lan> Message-ID: <20100107185927.GA31395@ovh.net> > I would imagine, however, that we will see increasing data center > temperatures more and more in the coming years. In 2004 & 2007 we developped the EcoDatacenter. 12 months per year, we use only the water & outside air for the cooling on our 70 000 dedicated servers that we host. We are #1 in Europe. Our PUE = 1.12. it means we don't waste the power for the cooling. That is why our prices are cheaper and our customers love it. It's our marketing.

For the 2651XM you have a huge lot of possibilities for different versions (depending on amount of RAM), and which one suits your needs would vary with what features you want to use. Without any information regarding the latter your question is incomplete. We have been using 12.2(40) mainline with several 2600s with no problems for a long time, though not with XM models. They're primarily 2610s used as RTR queriers and responders, and the a few devices for DLSw+ termination. Regarding the L3 switches: I was once told an expert I respect a lot (non Cisco employee) to generally use the newest supported version and hope for the best. We currently use (as the customer) a few hundreds of 3560s running 12.2(35)SE5 IP Services as multi VRF-Lite CPE devices in "branch offices". The only bug that has bitten us so far is that interface counters don't show drops (e.g. OutDiscards). We use lots of 3560s currently running 12.2(50)SE1 and SE3 IP Base and only doing L2. No problems so far. (And OutDiscard counters work.) We also have a handful of 3550s running 12.2(50)SE3 IP Base; this is not supported, but we haven't had any problems so far. We replace them with 3560s on occasion. (The 3550 was IMHO a better platform though.) Remember that if you are using the 3550s for anything critical you really should use a supported release. -- Peter From panocisco77 at gmail.com Thu Jan 7 14:08:38 2010 From: panocisco77 at gmail.com (Renelson Panosky) Date: Thu, 7 Jan 2010 14:08:38 -0500 Subject: [c-nsp] CIsco 6509-E issues In-Reply-To: <535857.93381.qm@web27904.mail.ukl.yahoo.com> References: <16e2ac180912290541n6cfcb6b2yb4de7a88f40bd7f7@mail.gmail.com> <535857.93381.qm@web27904.mail.ukl.yahoo.com> Message-ID: <16e2ac181001071108gd875460r3ff0a0e5460ccd21@mail.gmail.com> Thank you for all the responses i've received on this issue but i figured it out.

We do this and we have had mixed success. We have Liebert A/C units which have something they call an "economizer." Essentially, when the outside temperature falls below a certain point as measured by a simple thermostat, the A/C unit moves a damper and instead of sucking hot air from the room to cool, it sucks cold air from the outside, filters it, and blows it in. At the same time, it turns off the compressor (because the air is, in theory, already cold). In the sales presentations and talking to A/C gurus, it all sounded very smart and economical, but we've found that the actual management of the damper and the temperature that it shifts are very delicate settings. Depending on the time of the day (i.e., is there sunlight on that side of the building or not?) and the season of the year (i.e., is this just a little cold snap or an extended period?), as well as the outside humidity level (is it very different from the humidity in the room or not?), the temperature has to be adjusted a bit in each direction. Our units don't have a computer control for that, so that means someone goes out every few weeks with a screwdriver and manually fiddles the economizer thermostat settings. We can compensate a bit on the computer control side by changing the the system thermostat around a few degrees, but there is no direct linkage between the economizer part of the system--it's completely independent, essentially an add-on--and the rest of the cooling system. I honestly can't tell whether we are saving any money on this or not, but for our latitude and climate, I would not recommend it to anyone else. We have had to replace the thermostats and damper controllers, and that eats up $300 to $500 for every service call. Plus, while we were learning about it, we had some midnight room-got-too-hot moments, which also cost us. I think that if you lived someplace where it was in the 5C/40F range or below day-round for weeks at a time, this would probably work (assuming that you have physical ability to install this kind of unit). In our climate, where it is 5C/40F for 8 hours at night and 20C/70F the rest of the day, for our 3 month winter, it was probably not the right decision. jms -- Joel M Snyder, 1404 East Lind Road, Tucson, AZ, 85719 Senior Partner, Opus One Phone: +1 520 324 0494 jms at Opus1.COM http://www.opus1.com/jms From mulitskiy at acedsl.com Thu Jan 7 14:29:57 2010 From: mulitskiy at acedsl.com (Michael Ulitskiy) Date: Thu, 7 Jan 2010 14:29:57 -0500 Subject: [c-nsp] IRB and channel-group help needed In-Reply-To: <4B45D00D.9E6F.00B8.0@dps.k12.oh.us> References: <4B45D00D.9E6F.00B8.0@dps.k12.oh.us> Message-ID: <201001071429.57202.mulitskiy@acedsl.com> I have it working exactly this way. my IOS is 12.1(26)E7 the only special thing I remember about it is that if you want to spread port-channels across the different cards then those cards must be the same (or compatible).

I'm running Cisco IOS Software, C3750ME Software (C3750ME-I5K91-M), Version 12.2(46)SE, RELEASE SOFTWARE (fc2). > Any thoughts on what I should be checking? Hi Jared, I've run into the same problem on our 3750Gs and 3750Es (running 12.2(46)SE) with no solution so far. The log on our switches indicates that it's due to the config for the Port-Channel being different than the underlying Gix/y/z interfaces, which is not allowed, so it shuts the etherchannel down. I tried to work around this by adding the VLAN to all ports at once, eg: conf t int ran gi1/0/1, gi1/0/2, po1 sw trunk allowed vlan add 400 end ... but this didn't seem to help. This has been a constant problem with earlier IOS releases too so I don't believe it's just 12.2(46) to blame. I assumed there was a simple solution, but hadn't had enough impetus to search for it yet.

Both locations each have a single 45 M ISP link, and also have internal connectivity with each other through multiple private links. The private WAN connecting the two locations has plenty of bandwidth and the latency is less than 40 ms between the two sites. We have our own registered ASN and public IP ranges. We have multi-homed ISP links at several other locations but not at these two locations. Also, both locations are partly ready for multi-homing in that they already use our own IP range and run BGP to the provider using our ASN. We have been asked to implement failover, for both the locations. The options we are considering are: 1. Traditional multi-homing by adding a second ISP at each location. 2. Buying a leased line to connect the CER at both locations and letting the incoming traffic for either location transit over that line to provide failover when one site's ISP goes down. This link would terminate on the 'dirty' side of our firewall and not have anything to do with the internal WAN. 3. Setting up a VPN-type tunnel between the ISP routers at both sites that would be routed over our internal WAN. This is similar to option 2 but doesn't involve any extra cost. Obviously we would prefer option 1 as it is simplest and safest to set up, and we already have experience with that type of setup, however we have been asked to look at cheaper options due to budget constaints, hence wanted some advice on the other options, do you think they could work well, any potential issues we should look out for, or should we even be considering them?

This one Cat2948 is the only Layer 2 device between the DHCP/PXE boot server and the PXE client - both are directly connected and share a /24. PXE boot is not working at all, and DHCP is unbearably slow, for no apparent reason. Both PXE Server and Client(s) are various IBM xSeries using the onboard GBit interfaces. Now the fun stuff: when I put a second Layer 2 device between the Cat 2948 and the PXE client, it is magically working. Means: PXE Server -> Cat 2948 -> "some cheap Netgear Office switch" -> PXE Client == works. In fact, any additional Layer 2 device that appears between PXE Client and the Cat 2948 scares the problem away. Anyone seen this before? Any hints where to start looking?

No link speed or bandwidth issues, but your network will not be able to see anything within the 192.168.9/24 prefix (other than what is within your /27). All devices within your network will never go to the default gateway to route externally like they should, as all devices will think that the rest of the /24 is internal, rendering the subnet unreachable. Either render a /24 prefix on the router's fast Ethernet interface, or change the internal hosts to /27 as well.

Beyond that, your key concerns are complexity, cost and future growth. If you pick option 3 and you need to tunnel for security purposes, think through how you plan to deal with the reduced MTU of the tunnel. Depending on your server requirements, the cleanest approach is often to just reduce the MTU used by the server to match the tunnel, even though it is smaller than what you could use under normal circumstances. Also keep track of traffic so that when the backup link is put to use, you don't discover the hard way that traffic has grown to the point where it won't fit! Good luck and have fun! -- Vincent C.

I can take the subinterfaces off temporarily and set up the channel-group, but it I try and re-add the subinterfaces, I can't do that. Is this something that is possible? If so, what am I missing? I'm not completely clear on what is being attempted here, but if the goal is just to have a portchannel with 802.1q subinterfaces, you don't configure the subinterfaces on the physical interface, just the port-channel.

Only downside is having different serial/aux ports. nvram stays the same. bootflash stays the same. slot[01]/disk[01] become available more ethernet ports become available No bandwidth points are consumed so nothing needs to change slots. Not a bad arrangement. Interestingly enough, we did see an issue with a variant of CF flash that caused the boothelper, an older 12.3 image, to crash while booting with that CF in the IO controller, even as a fully booted IOS had no issue reading,writing,formatting it. A slightly older CF worked fine. An upgraded boothelper probably would have also solved the issue. The CF slot on the NPE-G1 (disk2:) seems to be toast.

This also depends on how well you're circulating the air within your data centre - having air at 25?C is fine as long as all that air actually reaches the things it needs to cool. If it's been mixed in with enough hot air by the time it's got to the top of the rack at the far end of each row however, you're going to run into trouble. Closer to the original topic, I do recall seeing a TV programme some time in the last few years that mentioned cooling the computer room at some Antarctic science base and they did still have to use compressors etc as it was easier than trying to make the outside air suitable, although I forget the details. (I suppose, at least, you could dump the warm air into the rest of the base but I seem to recall the computers were in a separate hut/building) From jmaimon at ttec.com Fri Jan 8 12:15:38 2010 From: jmaimon at ttec.com (Joe Maimon) Date: Fri, 08 Jan 2010 12:15:38 -0500 Subject: [c-nsp] spanning-tree bpdufilter leaks In-Reply-To: <4a15acd91001072113h4558ab79vb069989e5e453615@mail.gmail.com> References: <4B469FB7.6050208@ttec.com> <4a15acd91001072113h4558ab79vb069989e5e453615@mail.gmail.com> Message-ID: <4B47683A.6000405@ttec.com> Marko Milivojevic wrote: > On Fri, Jan 8, 2010 at 04:00, Joe Maimon wrote: >> >> Apparently, bpdufilter leaks sometimes on some switches, and I have >> the packet traces to prove it.

I tried to work around this by adding the VLAN to all ports at once, eg: > conf t > int ran gi1/0/1, gi1/0/2, po1 > sw trunk allowed vlan add 400 > For vlan changes on port channels, I've always used just the port-channel configuration (e.g., int portch1) and applying vlan adjustments there, which IOS appears to propagate to the active member configurations, provided of course the port channel is up. We do this "a lot" across a broad range of Catalysts (no MEs though) with no issues.

You'll get the whole syslog message on your NMS. Solution#2: use EEM to match syslog UP/DOWN messages, extract interface description and generate a custom SNMP trap. You can do it with EEM applets if your IOS supports EEM 3.0 (12.4(late)T, 12.5, 12.2SRE), otherwise you have to use a Tcl EEM policy (pre-EEM 3.0 applets are too dumb).

If the coils are compressor-cooled AND taking in fresh damp air, it can ice up really good. We had the damper get stuck once and cause that. We have more than one A/C unit, so one damper failing and messing up the A/C isn't the end of the world. We have 2 A/C systems. The addition of the economizers meant two good sized insulated ducts going from the air handlers to vent grates on the end of the building about 10' off the ground. There is also an exit louver in the hot section to allow efficient pumping of air without over-pressurization. We use an economizer. 44N latitude in Maine. Saves us good cooling money from mid november till april by not running the compressors. We see it looking at the power bills year round. Your climate description doesn't sound like an ideal place to really see the benefits of it. If you adjust the switchover temperature conservatively for the low side, you don't really have to worry about fiddling with it. It will of course vary for different locations, loads, building insulation, etc.. We have ours to switch at 48f, but could switch at a higher temp if we had a lesser load. We keep the space at 72f.

The "problem" is that when the exit PE receives the packet it doesn't do a RIB lookup (to send the traffic back to the correct recipient) but instead it just uses the "adjacency" from the MPLS forwarding table to send it to the next (non MPLS) device. Is there any (easy-ish) way to force the exit PE to do a RIB lookup (e.g. using the allocated aggregate label) and send the packet the right way by itself? If so, would there be any significant performance penalty from this on a Sup720/PFC3B? The reason why it doesn't work now is that the device after the exit PE is a firewall. Specifically FWSM v3.1. It denies the ICMP TTL Exceeded, stating "no matching session" as the reason. When the trace probes have got to the point (TTL wise) where they pass the firewall, all TTL expired replies are accepted and in the end received by the originating client. If there's a way to make a FWSM accept TTL expired like this I'd love to know. (I tried "same-security-traffic permit intra-interface" to defeat the "no xlate" but then the reverse path check fails. I even tested with no reverse path checking, but still couldn't make it pass (=return) the ICMP TTL expired packets.)

According to some Cisco guys we spoke to the hardware is not capable of doing that lookup if there is a forwarding adjacency.

Unless you arrange that upstream-heard bgp-announcements of these subnets are propagated to your partial-routing-table routers, those routers will be unable to reach the dual- homed customers when its link is down to you, even if its link to another upstream is working.

Message-ID: Hi all, A colleague recently told me not to use BGP peer groups because he insists that there a drawbacks to using them. Does anyone know of any drawbacks to peer groups???? I dug the following up on the Cisco website: "Cisco IOS Software Releases earlier than 11.1(18)CC have the limitations described in this section. Failure to adhere to these rules can result in inconsistent routing. If you use peer groups for clients of a route reflector, all the clients must be fully meshed. If you use an eBGP peer group, transit cannot be provided among the peer group members. All eBGP peer group members must be from the same subnet to avoid non-connected next hop announcements. However, these limitations were removed starting with Cisco IOS Software Releases 11.1(18)CC, 11.3(4), and 12.0. Only the router on which the peer groups are defined needs to be upgraded to the new code." But the above limitations have now gone, so I can't think of what drawbacks he might be refering to.

So it makes sense to me. I don't think scale is the only deciding factor between peer group and templates. I think it also depends on the complexity of your routing policy and # of prefix's etc...I guess a question could be - why wouldn't you use templates - even for a simple BGP config?

They were meant to solve different problems. When they were introduced, peer-groups were used to optimize the updates sent to neighbors. I.e. using peer-groups had impact on your CPU in such a way that members of the same peer group shared the same update that was only replicated. Non-peer-group peers had to have their updates built separately, even though it may end up being the same. The fact that the peer-groups had this nice side effect of being able to group configuration and make deployments somewhat easier, was never their primary purpose in life... and that shows, as they look unnatural and are not very flexible. Naturally, over the years, Cisco found the way to optimize updates automatically (using update-groups) and the only purpose of peer-groups was to group commands together.

Any ISP ops on the list - do you > use templates, peer-groups - or both? We use templates, including inheritance. They're very handy. From memory however, some things don't quite work with them - the only specific example I can think of is using a "bgp listen" e.g. on a route-reflector, which will allow any BGP router from a particular subnet range to connect. IIRC on 12.2SX, when I tried it, it didn't support templates, just peer-groups. We see some oddities with VPNv4 AFs too; the send-community commands seem to not get inherited, but are automatically added to the neighbour statements, and soft-reconfig refuses to apply, but AFAICT these are cosmetic. That said, we use a peer-group in one or two places where the config is very simple and confined to one router (anycast DNS via eBGP, specifically) I would use templates in a new deployment, and recommend against peer-groups - Marko's email has an excellent summary of the background.

That means, peers belonging to the same peer-group, or with the same peer-policy template or even without peer-groups or templates configured but with the same policy applied. The optimization brought by update-groups is obtained because as all the neighbors have an equal policy IOS knows that it needs to calculate a single set of updates to all of them, in older versions it used to calculate updates for each neighbor, even though they had equal policies.

However, templates allow you to get much more granular with your routing policies. It's more like comparing red apples to green apples - green are more sour (peer groups).

Have you tried enabling "mpls label protocol both", either globally or on interfaces that you want to run both LDP and TDP? I believe that pretty much every IOS supports running both. I'm yet to see one that supports both, but can't run them concurrently. -- Marko Milivojevic - CCIE #18427 Senior Technical Instructor - IPexpert Mailto: markom at ipexpert.com Telephone: +1.810.326.1444 Fax: +1.810.454.0130 Community: http://www.ipexpert.com/communities From andy.saykao at staff.netspace.net.au Sun Jan 10 18:57:31 2010 From: andy.saykao at staff.netspace.net.au (Andy Saykao) Date: Mon, 11 Jan 2010 10:57:31 +1100 Subject: [c-nsp] Service Provider products References: Message-ID: <56F211C5E3F24F47B103EA1B253822BE044AB09E@vic-cr-ex1.staff.netspace.net.au> Hi Jack, I used a multitue of books and online tutorials/labs when designing our MPLS network.

The release notes he is quoting are from 1998, anyone who is still running 11.1(18)CC probably has bigger problems than their peer groups. As for BGP templates, it has nothing to do with scale. BGP templates are simply the newer and better replacement for the peer group functionality, that adds more features and is less restrictive. Anyone doing a new deployment should probably use the new system instead, unless there is some specific reason not to (e.g. a noc which isn't capable of learning new things, etc). -- Richard A Steenbergen http://www.e-gerbil.net/ras GPG Key ID: 0xF8B12CBC (7535 7F59 8204 ED1F CC1C 53AF 4C41 5ECA F8B1 2CBC) From avayner at cisco.com Mon Jan 11 04:29:09 2010 From: avayner at cisco.com (Arie Vayner (avayner)) Date: Mon, 11 Jan 2010 10:29:09 +0100 Subject: [c-nsp] BGP Peer Group drawbacks??? In-Reply-To: References: Message-ID: I think this would provide a comprehensive overview: Peer-Groups are a relatively old feature which was introduced to provide two functions: - Reduce BGP configuration by creating a "template" which can be reapplied to multiple peers - Reduce CPU workload for BGP updates, as all members in a peer-group had the same egress policy, so an update had to be computed only once As combining both functionalities into a single feature is a bit restrictive (you have to have (mostly) the same config for all peers) then this was basically split up: - Dynamic Update Groups are built on the fly for BGP peers with similar update (output) policies. This allows for CPU load reduction. - Templates are used to build config templates to reduce configuration complexity/clutter.

Hi all, A colleague recently told me not to use BGP peer groups because he insists that there a drawbacks to using them. Does anyone know of any drawbacks to peer groups???? I dug the following up on the Cisco website: "Cisco IOS Software Releases earlier than 11.1(18)CC have the limitations described in this section. Failure to adhere to these rules can result in inconsistent routing. If you use peer groups for clients of a route reflector, all the clients must be fully meshed. If you use an eBGP peer group, transit cannot be provided among the peer group members. All eBGP peer group members must be from the same subnet to avoid non-connected next hop announcements. However, these limitations were removed starting with Cisco IOS Software Releases 11.1(18)CC, 11.3(4), and 12.0. Only the router on which the peer groups are defined needs to be upgraded to the new code." But the above limitations have now gone, so I can't think of what drawbacks he might be refering to. Anyone know?? THanks in advance! _________________________________________________________________ We want to hear all your funny, exciting and crazy Hotmail stories.

From the following doc: http://www.cisco.mn/en/US/docs/switches/lan/catalyst3550/software/release/12.2_44_se/configuration/guide/swtunnel.html The priority field on the metro tag is set to the interface class of service (CoS) priority configured on the tunnel port (the default is zero if none is configured). IEEE 802.1Q Tunneling and Other Features Although IEEE 802.1Q tunneling works well for Layer 2 packet switching, there are incompatibilities between some Layer 2 features and Layer 3 switching. ?Tunnel ports do not support IP access control lists (ACLs). ?Layer 3 quality of service (QoS) ACLs and other QoS features related to Layer 3 information are not supported on tunnel ports. MAC-based QoS is supported on tunnel ports. What does one need to support Layer-2 QoS on QinQ, newer Juniper EX switches? Cisco 3750's?

Gi1/2 on the same 6724s connect to a 3845 which is my other border and it shows significantly lower drops and flushes (4 digits instead of 7 or 8). All 4 links are SX. 'sh counters' didn't yield anything terribly interesting either. 7613-1.clr#sh counters interface gi1/1 delta | e = 0 Time since last clear --------------------- never 64 bit counters: 0. rxHCTotalPkts = 123760873738 1. txHCTotalPkts = 45947101814 2. rxHCUnicastPkts = 123747989684 3. txHCUnicastPkts = 45941233718 4. rxHCMulticastPkts = 12883997 5. txHCMulticastPkts = 5868073 6. rxHCBroadcastPkts = 57 7. txHCBroadcastPkts = 23 8. rxHCOctets = 101377579108374 9. txHCOctets = 16976124978053 10. rxTxHCPkts64Octets = 8893600878 11. rxTxHCPkts65to127Octets = 57698604883 12. rxTxHCPkts128to255Octets = 20633513794 13. rxTxHCPkts256to511Octets = 7123204457 14. rxTxHCpkts512to1023Octets = 6652027912 15. rxTxHCpkts1024to1518Octets = 26440990980 32 bit counters: 2. rxOversizedPkts = 2492150694 13. linkChange = 2 All Port Counters 1.

All the QoS Lost lines were 0. All infrastructure interfaces are also MPLS enabled. The 7206 carries the bulk of the Internet traffic as does 7600 #1 so it's not a big surprise to see its links affected much more so than the 3845 links. I'm graphing interface errors/discards with Cacti. I have to question the numbers it's giving me though. They have never seemed to be accurate to me on any of my interfaces. Are my queues not deep enough to carry the traffic flow? Peak Mbps on through the 7206 is about 120Mbps and if Cacti is right then we're also only talking about 17,000 pps on the upstream-facing interface of the 7206, most of which would come from 7600 #1. Thoughts?

But of you for instance use it for its strengths, webgui, report builds and user handling and then using something like SEC (http://simple-evcorr.sourceforge.net/) for the event notifications then I think you will be happy. /Anders.

But now I just realized just change the IP address on the ATM sub-interface on the router and get the customer to renumber to the new IP. No changing of PVC's needed. There is another faste interface on the 7204 that would connect to a new switch which goes out to a new upstream that the new block of IP's would route and would allow customers to use the old IP blocks until we get them to renumber. This is all just off the top of my head but it seems either should work. Anyone see a problem with this renumber?

It started out where the system would run on the supervisor in slot 8 for about 16-24 hours, then fail over to the secondary supervisor on slot 7 for "no" reason, then this error would be presented, and then it would immediately flip back to slot 8. Originally the error message was: Jan 12 09:36:03.144 EST: %FABRIC-SP-3-DISABLE_FAB: The fabric manager disabled active fabric in slot 7 due to the error (2) on this channel (FPOE 8) connected to slot 4 We re-seated the card in slot 4, and eventually replaced it and everything seemed to finally stabilize. This morning, as a test I forced it to switchover to the card in slot 7 to see if it would immediately switch back to the card in slot 8 it did not, and I was fairly pleased, however we now got this error: Jan 12 09:36:03.144 EST: %FABRIC-SP-3-DISABLE_FAB: The fabric manager disabled active fabric in slot 7 due to the error (2) on this channel (FPOE 8) connected to slot 13 We went to re-seat the completely unused 6548 card in slot 13 (this is a 6513) and it caused a failover again. Jan 12 09:35:10.353 EST: %OIR-SP-6-REMCARD: Card removed from slot 13, interfaces disabled Jan 12 09:36:03.144 EST: %SYS-SP-3-LOGGER_FLUSHING: System pausing to ensure console debugging output.

If your WAN uplink is a subrate link (i.e. a 1GigE port with an SLAN of <1GigE) you need to perform egress shaping on that interface, which is not supported on 3550 (or most LAN switches).

At the moment we have an L3VPN terminating GigE at the remote end on a 7301 and DS3 on a G1 with PA-2T3 at the head office. Link does 10Mbit about half split between voice and data. The new carrier has provisioned a 45Mbit clear channel service with a DS3 at the remote site, and a channelised STM1 at the head office. I can't seem to find a combination of router/card/mux to make this work. - Cisco 7200 with PA-MC-STM1 can't channelise larger than E1. - Cisco 7600 with SPA-1XCHSTM1/OC3 can do it according to the spec sheet for the SPA, but is incredibly over-speced and pricey. - Adtran Opti-3 is SONET/OC3 only (but I can't find confirmation of this). - Juniper M7i with STM1 IQ PIC can't channelise larger than E1. - Juniper M7i with OC3 IQ PIC can channelise DS3, but doesn't do SDH framing for STM1. - The carrier suggested re-engineering the service to deliver 21 E1s and run MLPPP over them. The data sheet for the PA-MC-T3-EC indicates MLPPP is only possible in hardware up to 12 T1s. I doubt MLPPP in software would perform at all, let alone perform well. I've never worked with channelised services more complicated than DS0s in an E1, so I've got a few questions: - Has anyone ever done this? What config/hardware did you use? - Are there any muxes/converters/router interfaces that can do this at the ~20Mbit end of the market? - Does the Adtran support intermixing of SONET and SDH (DS3 over STM1)? Many thanks, - I.

You could call it a cosmetic issue, but I see myself making mistakes because the burden is on me to translate the icmp types as I enter config :( I would certainly open a tac case and insist on getting a bug id. C's v6 support across across product lines is pretty craptastic. I recently got CSCtb29296 filed. This is very, very, basic broken functionality that shows their v6 feature support and testing is negligible.

Message-ID: We've been seeing some strange behavior on our 7609-S running 12.2(33r)SRB4. We have a VLAN (with four /24s) configured on three ports across two 10/100/1000 blades facing some FTTH transport equipment. Customers hanging off the FTTH equipment on the third port are complaining that several times per day they lose internet access. We've been able to correlate their complaints with failed ping attempts from our workstations and the 7609-S to their public IPs. What's interesting is that it's not all the traffic, and of the 4 IPs we are tracking, two of which are on separate /24s, the outages happen within the same /24. At the same time, while using Wireshark, I can see one of the Cisco interfaces sending out 1 to 2 Mbps of traffic that should be going to one of the other two Ethernet interfaces. This is happening about a dozen times per day for 4 to 6 minutes at a time. While the event is occurring I have verified the ARP and CAM entry. The CAM entry is associated with one of the first two Ethernet interfaces, not the third. I can clear the ARP and CAM entry from the CLI and they are re-learned with the same information, yet the traffic continues to egress the wrong Ethernet port. I've set the ARP timeout to 4 minutes so that it's less than the CAM table's default configuration of 5 minutes, but there was no improvement. One more observation -- the errant port is the root of the bridge. Any ideas why the 7609 would be sending traffic out an Ethernet port to a device that the CAM table says is on a different Ethernet port?

Message-ID: <4B4D6234.7050101@darkman.de> -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi there, i'd like to use the pvlan feature from Cisco for two networks. I already read a lot of documentation on the pvlan feature on ciscos page and mayn other blog posts etc. and already know, that it seems not to be possible to use the pvlan feature with etherchannel/port groups on any device. A part from no information *why* this is not possible, i have no idea, how to complete the following setup: I'd like to have my PVLAN connected to my "core" network in a kind of redundancy and "more" bandwidth. The PVLAN has GBIT enabled devices, the uplink to the core should be more than one GBIT (to ensure that no single device is able to fill the uplink, but also able to use max of avaiable bandwidth). Sadly, a TGigE Uplink is not yet possble. As switches we have 3560G and the core is currently a 6509. At least the redundancy is important, so i could try it with "backup-interface" on the 6509, but this would limit the pvlan to 1GigE, which is not exactly what i want. Another problem is, that i currently plan to deploy two isolated pvlans on the 3560 switches, which "should" be no problem if i use two different primary vlans (a primary may only carry one isolated pvlan at a time), but it seems to be not possible to use one uplink/trunk port for two different isolated pvlan setups? If thats true, i would need at least four ports (two for each isolated pvlan) just to get the redundancy and would not have any uplink >1GigE... Did i miss anything? is there a way to get the redundancy and the bandwidth? may i use two isolated pvlans on the same uplink? Is there some way to use something "like" etherchannel with pvlans? Or is there a way to change the setup in a way i would get pvlan + more bandwidth + redundancy without all of these problems or limitations? ;) Thanks and regards, Sven -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.9 (GNU/Linux) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iEYEARECAAYFAktNYjQACgkQQoCguWUBzByRRgCgqzWhNR6O/GNSjQZUhjAMw/+z rrAAoK4X2X5ti4MibH7r1dUUCDpf/S05 =3btI -----END PGP SIGNATURE----- From td_miles at yahoo.com Wed Jan 13 02:10:06 2010 From: td_miles at yahoo.com (Tony) Date: Tue, 12 Jan 2010 23:10:06 -0800 (PST) Subject: [c-nsp] Ethernet Network In-Reply-To: Message-ID: <499475.32176.qm@web110115.mail.gq1.yahoo.com> --- On Wed, 13/1/10, Lasher, Donn wrote: > > >> SNIP >> > >1500 bytes max data + 22 max header + 4 CRC trailer + 4 > byte 802.1q tag > >+16 up to 4 labels = 1546? > > > >Why not just enable jumbos and set it as high as > possible? > > > 1546 = largest MTU the 355x/356x switches, PA-FE, etc, will > support, as > I recall. > PA-FE are limited to 1530.

On those links you can use normal "trunk" ports and spread the PVLAN to your 6509 and terminate it on L3 VLAN int. Access layer example for end-user port somewhere in the deeps of the switched fabric: interface FastEthernet0/1 switchport mode private-vlan host switchport private-vlan host-association 10 100 Access layer trunk port: interface GigabitEthernet0/1 switchport mode trunk On your distribution (6509) you configure: interface Vlan10 ip sticky-arp ignore <--- this is important as PVLAN VLAN interface gets sticky arp by default (for some unknown reason) no ip proxy-arp private-vlan mapping 100 and normal trunk port towards the switch fabric: interface GigabitEthernet6/1 switchport mode trunk Yes this is probably suboptimal to what you would like to accoplish however the end effect is that the end-user ports cannot communicate with each other - which is probably what you want. Another alternative is the "private-vlan trunk" feature which is described over here http://www.cisco.com/en/US/docs/switches/lan/catalyst4500/12.2/31sga/configuration/guide/pvlans.html#wp1166138 - the trouble is that AFAIK currently it works only on C4500. -pavel skovajsa On Wed, Jan 13, 2010 at 7:03 AM, Sven 'Darkman' Michels wrote: > -----BEGIN PGP SIGNED MESSAGE----- > Hash: SHA1 > > Hi there, > > i'd like to use the pvlan feature from Cisco for two networks.

You could call it a cosmetic issue, but I see myself making mistakes because the burden is on me to translate the icmp types as I enter config :( > > > I would certainly open a tac case and insist on getting a bug id. Yeah I asked Brandon unicast to open a new case and get me the #. However: The issue comes from the icmp-type object group being a separate entity from an ACL, that is not context-aware ("www" is always 80), and it can not really be "fixed": if you were to use the same icmp-type OG in the IPv4 and IPv6 ACL- what should the type "3" correspond to in the running config within that object group ? There's not always 1:1 mapping between ICMPv4 and ICMPv6. So it is not as black and white as printing IPv4 instead of IPv6, unfortunately... Looks like the only approach might be creating a new object-group kind "icmp6-type" - and make the CLI not accept the "icmp-type" object group for the IPv6 ACLs. cheers, andrew From timothy.arnold at uksolutions.co.uk Wed Jan 13 07:31:56 2010 From: timothy.arnold at uksolutions.co.uk (Timothy Arnold) Date: Wed, 13 Jan 2010 12:31:56 +0000 Subject: [c-nsp] IPv6 ns-interval & 12.2(33)SRE & ASA 8.2(2) Message-ID: Hi Guys, I'm hoping there is someone out there who knows a bit more about IPv6 that I do :) Enabled ipv6 between the Cisco 7600 running 12.2(33)SRE and a pair of Cisco ASA firewalls running 8.2(2) (in HA).

Thanks for reminding me about this article. When I do a "sh mac-address-table", am I looking at what's on the Supervisor or line card's DFC? When I turn it on, I get this message: Mutual_7609(config)#mac-address-table synchronize % Current activity time is [160] seconds % Recommended aging time for all vlans is at least three times the activity interval The aging time of the CAM? By default it's 300 seconds, so working backwards, I would want a "Current activity time" of 100 seconds, but that doesn't appear to be an option. So I've now increased the mac address-table aging time for that VLAN to 480 seconds (3 x 160) and the arp timeout also to 480 seconds. > How long has this been happening for? We've had the first two interfaces in production for several months. We just turned up this third interface two or three weeks, and started moving customers on there and they started complaining last week, so extrapolating from that I'm pretty confident it's been doing this the whole time.

Well, on a 6500 under SXI, it shows me things like: Module 1: * 1740 0000.0c07.ac00 dynamic Yes 160 Po1 * 1740 001e.2a6f.5c37 dynamic Yes 220 Po1 * 1740 0015.c706.8c00 dynamic Yes 170 Po1 Module 2[FE 1]: * 1740 0000.0c07.ac00 dynamic Yes 0 Po1 * 1740 0015.c706.8c00 dynamic Yes 170 Po1 Module 2[FE 2]: * 1740 0015.c706.8c00 dynamic Yes 170 Po1 ...leading me to believe it's querying all the forwarding engines on all the modules but NOT the PFC on the sup (module 5 in our case) - possibly because we've got DFCs in all slots? As the example shows, the module and even FE tables within a module can differ. You can get the raw module local tables (and the PFC one) using: remote command module N sh mac-address-table [dynamic] [vlan N] If the active sup is in slot 5, these are equivalent: remote command module 5 remote command switch ...and on the sup I see, using the above example: Displaying entries from SP: RM PI_E RMA Vlan Destination Address Address Type XTag LTL Index ---+----+---+------+---------------------+-------------+----+------------- No Yes No 1740 3333.0000.0016 static 0 0x802 No Yes No 1740 3333.0000.0001 static 0 0x802 No Yes No 1740 3333.0000.000d static 0 0x7FF8 No No No 1740 0000.0c07.ac00 dynamic 0 0x340 No Yes No 1740 0015.c70b.9000 static 1 0x380 No No No 1740 001e.2a6f.5c37 dynamic 0 0x340 No No No 1740 0015.c706.8c00 dynamic 0 0x340 ...which looks like an amalgam of the module MAC tables. We're not running mac sync or anything odd. You can "remote command [switch|module N]" (or "attach N") and run sh mac-address-table detail ...but based on the deafening silence in response to a query the other week, no-one knows what those flags mean - maybe you can see a pattern in your problematic entries though (yay I just love reverse engineering the 6500 forwarding architecture - thanks cisco!) > > When I turn it on, I get this message: > > Mutual_7609(config)#mac-address-table synchronize > % Current activity time is [160] seconds > % Recommended aging time for all vlans is at least three times the > activity interval > > The aging time of the CAM?

Interestingly, at some point when I was testing either SXH or SXI, I recall this very time (480 seconds) magically popped into the nvgen without any input from me. I can't remember when, and it seems to not be there now. I've seen hints that VSS systems use the mac sync / move notify stuff behind the scenes to sync up MAC tables across chassis - of course since you're on a 7600 that should not be relevant. sh mac- sync stat ...might be illuminating now that you've got it running, but I'm afraid the output baffles me...

A TE tunnel is for sending traffic, not for receiving. PIM neighborship hence is established on physical interface, not on the TE interface coz you need bidirectional flow between the neighbors. RPF failures may happen when you receive multicast traffic via physical interface while the routing table has a route via TE interface. Either "mpls traffic-eng multicast-intact" or static mroutes can be used to solve these RPF issues. Forwarding adj doesnt work with multicast-intact feature.

Why is that suboptimal? From what you described and what i unterstood, it works like i want: having a etherchannel to my core and protected ports on my edge. If the SVI is reachable from my edge, and other hosts are not, than i have what i want. But maybe i missed something...? > Another alternative is the "private-vlan trunk" feature which is > described over here > http://www.cisco.com/en/US/docs/switches/lan/catalyst4500/12.2/31sga/configuration/guide/pvlans.html#wp1166138 > - the trouble is that AFAIK currently it works only on C4500. That was what i thought i need, its available on the 3560 but it killed the etherchannel... and pvlan documentation says "you cannot enable pvlans on an etherchannel", which is "right" as if you enable any of the pvlan commands on a etherchannel port, it gets removed from the etherchannel... but it seems that normal trunks just work for that - great ;) So, from what i know now, it should work like i want... just need to test if it works with more than one switches etc. but at the moment it think it will do so far.

No matter where the BGP-->OSPF redistribution point is, if it's the PE or CE, the routes will still show up (by default) as OSPF external, and will never be prefferred. The provider who's path we prefer will only run BGP. We would like to use OSPF everywhere if possible, for several reasons. WAN provider A is a layer-3 VPN MPLS network, and is the prefferred path. WAN provider B is a layer-2 VPN MPLS network over which we run OSPF. Provider B's network is inferior at times and we use it as a backup. The equipment where the eBGP peering relationsips exist is a mix of 7600, 3800, 2800, 1800, 6500, 3750, 3550. We considered GRE over the providers network however we then wind up with 25+ tunnels at each location, and that just grows as each new site is added, not to mention some potential issues regarding throughput with a GRE tunnel in the path. Is there a way to redistribute BGP into OSPF so that the routes can be anything but OSPF external? I have not found a way to do this yet, and was wondering if it's even possible, or if I'm missing something obvious. Any suggestions appreciated.

If these sites belong to the same OSPF area, the path over a backdoor link will always be selected because OSPF prefers intraarea paths to interarea paths. (PE routers advertise OSPF routes learned over the VPN backbone as interarea paths.) For this reason, OSPF backdoor links between VPN sites must be taken into account so that routing is performed based on policy. -----Original Message----- From: cisco-nsp-bounces at puck.nether.net [mailto:cisco-nsp-bounces at puck.nether.net] On Behalf Of null zeroroute Sent: Wednesday, January 13, 2010 2:20 PM To: cisco-nsp at puck.nether.net Subject: [c-nsp] BGP to OSPF redistribution I'm having a problem trying to figure out a way to get eBGP learned routes (from a layer-3 VPN MPLS WAN provider) into our internal OSPF, so that the routes learned via the provider are preffered over the internally learned OSPF routes. No matter where the BGP-->OSPF redistribution point is, if it's the PE or CE, the routes will still show up (by default) as OSPF external, and will never be prefferred. The provider who's path we prefer will only run BGP. We would like to use OSPF everywhere if possible, for several reasons. WAN provider A is a layer-3 VPN MPLS network, and is the prefferred path. WAN provider B is a layer-2 VPN MPLS network over which we run OSPF. Provider B's network is inferior at times and we use it as a backup. The equipment where the eBGP peering relationsips exist is a mix of 7600, 3800, 2800, 1800, 6500, 3750, 3550. We considered GRE over the providers network however we then wind up with 25+ tunnels at each location, and that just grows as each new site is added, not to mention some potential issues regarding throughput with a GRE tunnel in the path. Is there a way to redistribute BGP into OSPF so that the routes can be anything but OSPF external? I have not found a way to do this yet, and was wondering if it's even possible, or if I'm missing something obvious.

That would probably give us quite a bit of control. I recall having mixed experiences with a similar config related to BGP->EIGRP redistribution though, I'll definitely need to lab it up because it seems the metrics are calculated a bit differently based on what type of OSPF route it becomes. I need to brush up on my OSPF. For example: At the bgp->ospf redist border router... router ospf 1 redistribute bgp blah distance ospf external 19 Or... access-list 100 permit router ospf 1 redistribute bgp blah distance 19 0.0.0.0 100 Thanks to all for your suggestions!

On this router/switch, then redistribute the OSPF networks between the two processes (as noted earlier, be sure to prevent loops with route-maps). Now all the OSPF routes are seen as External (not necessarily ideal, but it works), and you can then set the OSPF metric (cost) higher on the neighbor adjacency(s) than taking routes learned from the BGP redistro. You could also do some summarization here too, which would prefer the more specific route from BGP (may or may not be possible with your design). -Mark Date: Wed, 13 Jan 2010 16:52:02 -0500 > From: null zeroroute > To: Vincent C Jones > Cc: cisco-nsp at puck.nether.net, Mikael Abrahamsson > Subject: Re: [c-nsp] BGP to OSPF redistribution > Message-ID: > > Content-Type: text/plain; charset=ISO-8859-1 > > Thanks for your suggestion.

Message-ID: <20100114112522.GA20074@samstag.members.selfnet.de> Hi all, Does somebody has experiences with STM-16 to GE multiplexers/converters? We have several links from a fiber distributor which expects STM-16 framing (there are some active WDMs etc.). At the moment we have an SDH overlay and SDH components at each POP. They divide the STM-16 to at least one time STM-4 (and the router handles the STM-4). We want to get rid of the SDH components, and use GE at the router side. Therefore, we want to split the STM-16 (2.5GBit/s) in 2x or 4x GE lines (yes, 4x is oversubscribed, but for backup links ok). We have found, for example, this SDH multiplexer: http://www.pandacomdirekt.com/de/produkte/netztopologie/sdh/speed-dualmux-sfp-25.html Does somebody has experiences and/or other verdors?

Ah, okay. But that i try to limit with other features (things like limited broadcast for a port etc.) so this should not be a big deal, should it? The main goal is to prevent "local" attacks from one server to another, like having a compromised host sniffing the rest after flooding the mac table, or do some arp spoofing... or what so ever ;) This should be still the case, even with the trunks, right?

What he's saying is that any time you redistribute BGP into $IGP, you are playing with fire. The likelihood of a mistake may be low but the cost of a mistake is high. One thing you'll definitely want to use is the 'redistribute maximum-prefix' command: router ospf $PID redistribute maximum-prefix $LIMIT This should help limit the damage if there's a redistribution "accident". --Jeff From mksmith at adhost.com Thu Jan 14 12:16:06 2010 From: mksmith at adhost.com (Michael K.

This example shows a 7200 with two connected routers. I also got fram-relay termination working with a 6500 but that platform does not seems to support the command needed to create frame-relay PVC's the frame-relay route command. Another thing I found for some reason on the 7200 I had to disable frame-relay inverse arp with the frame-relay map command for it to work. On the 6500 this was not an issue. I also noticed on the 7200 that on some interfaces for whatever reason, int ser5/0:1 I needed to have the frame-relay map statement for 1.1.1.1 to be able to ping it. This again was not an issue on the 6500. Also remember you will need frame-relay switching command in global config mode for the router to be turned into a frame-switch. Hope this helps someone.

I followed the example here, http://www.ciscopress.com/articles/article.asp?p=170741 &seqNum=7 but this will not work for me as it assumes you have 2 different frame-relay circuits on two different t1 ports. I'm using a PA MC T# canrd and I also tried creating sub interfaces off the t1 channel, but when I use the frame-relay route command I gives me an error that both DLCIs are on the same interface L.

We want to use the /24 for site B and announce the /21 and /23 from site A.

There are a few obvious deviations from the best practice design guides. The current setup is: Core --> Datacenter Distribution --> | (fiber connect) | --> Building Distribution --> Access (backbone) (ABR) (ASBR) (OSPF enabled access switch) The Cisco best practice is: Core --> Distribution --> Access (backbone) (ABR) (OSPF enabled access switch) We are running NSSA with no-summary and the range command on the Datacenter Distribution routers. Each floor has 2 access switches (w/ OSPF running) which each have a link back to the Building Distribution router. Vlans on each box on each floor are mutually exclusive. Symptoms: Lots of SPF re-calculations, NTP failing from Datacenter Distro -> Building Distro, and users reporting loss of their shared drives. router-a#sh ip ospf stat Area 0.0.0.0: SPF algorithm executed 7865 times Area 192.8.208.0: SPF algorithm executed 386 times Area 192.70.0.0: SPF algorithm executed 563 times Area 192.100.0.0: SPF algorithm executed 93076 times Questions: Should we be advertising (passively or non-passively) L3 Vlans into OSPF? Should we be doing Totally NSSA's instead of NSSA's? If not is there a way to get the DR in NSSA to advertise a single route back as default route? Should we be sending each campus distribution router directly to the Core so that its the 3 hops? Do you suggest tuning the OSPF dead interval to achieve subsecond convergence? Any help advise is greatly appreciated!

Use commands like above "show ip ospf stat" and looks for Seq# and LSA Age to find the flapping LSA.

Why would somebody do that in non-passive way and have miriads of neighbors per each vlan? > Should we be doing Totally NSSA's instead of NSSA's? Totally stubby (or totally not-so-stubby if you need ASBR) should be default design, only configure no-summary if you have specific reason. Also I don't understand the need for ASBR in your NSSA - but you probably have a reason for that. > ? ? ? ?If not is there a way to get the DR in NSSA to advertise a single route back as default route? > Should we be sending each campus distribution router directly to the Core so that its the 3 hops? As written above, if you have the funding to do this it will certainly make your network design nicer, but I don't see how doing this would actually massively decrement your SFP runs.... > Do you suggest tuning the OSPF dead interval to achieve subsecond convergence? Scale and speed are contradictory goals.

We use tac_plus with accounting, no problems there. The relevant configuration is: accounting file = /var/log/tacacs-accounting.log or similar in the tac_plus.conf file, and then: aaa accounting exec [method] start-stop group tacacs+ aaa accounting commands 0 [method] start-stop group tacacs+ aaa accounting commands 15 [method] start-stop group tacacs+ aaa accounting connection [method] start-stop group tacacs+ besides you normal AAA config on the Cisco devices.

They were terrible. I've never seen an application so poorly written that ran something as simple and dns and dhcp. I'll can tell three stores.... On one particular occasion we were applying updates to apply new tz information as DST was changing by a few weeks. I called for support since everything was running slow and basically got blamed for waiting too long to apply the patches. Apparently they didn't have enough capacity to handle the load since the patches were time sensitive. We also had a number problems with dynamic DNS. The machines were configured in a cluster which would fail from time to time for no reason. When this happened the DHCPID or txt records for the dynamic client would get lost and the clients wouldn't be able to update their own record later. Lastly, if the client and appliances were running different version of code the client could corrupt the config while applying changes. A number of time, we had other admins update to the latest client without knowing that the server had to match. Unfortunately, the thing wasn't smart enough to check the client version and throw an error. We moved back to a few redhat boxes and haven't had any trouble since. I'd recommend against a bluecat appliance based on our experience.

In every deal I have been involved in it has been the Server team deciding to move forward with UCS purely on its merits as a Data Center virtualization platform. Rather, its usually the Network team that comes in towards the end and gives their stamp of approval with respect to how the system interconnects to the Data Center core. In other words, if your Cisco account team is putting the pressure on you (the Network team) to convince the Server team to buy UCS, I can tell you from experience they are going about it all wrong :) Cheers, Brad -- Brad Hedlund, CCIE #5530 Consulting Systems Engineer, Data Center bhedlund at cisco.com http://www.internetworkexpert.org On Jan 14, 2010, at 11:31 AM, Eric Cables wrote: > Our local sales team has really been bombarding us with material on Cisco's > UCS (Unified Compute System) as of late, and I was wondering who on this > list has begun deployment of UCS.

Router A also learns site B's /24 via the private link as an OSPF route with an AD of 110(as shown in your?"sh ip route x.x.x.x/24)?and puts the route learned via ospf in this IP routing table and FIB since it has a better AD : 110 as opposed to 200.

Having explained the *normal-behavior* you are seeing in router A, my question is: ? 1) Are you trying to announce site B's /24 from site A to your upstreams OR 2) You are trying to announce your site-B /24 *from site B and that is failing. ? If your are trying to announce site B's /24 from site A to it's upstreams you already have the "answer" to make that work! (deploy a lot of outbound filters before you redistribute iBGP into eBGP) ?

In order to get the real benefit of VSS you would need all the access switches connected to both VSS nodes, which would require links from DC1 to DC2 per each access switch... The same would apply to upstream Layer 3 connectivity... If you do not plan to have this kind of a full mesh, then why would you want to use VSS in the first place. With regards to layer 2 interconnect between DCs, this is a very common design nowadays, and MPLS is used in many solutions. I suggest you take a look at this link: http://www.cisco.com/en/US/netsol/ns975/index.html (take a look at the whitepaper). Also, there is a very good Cisco Press book about this whole subject: http://www.ciscopress.com/bookstore/product.asp?isbn=9781587059926 In the coming Networkers event in Barcelona there would be a few sessions about this, and a number of people in Meet the Engineer venue which can help with this subject.

The most trivial solution would be to get a redundant point to point Layer 2 service (2 layer 2 circuits) which would be used to connect the 6500 devices. As you are running VSS, the two links can be bundled into a MEC (Multichassis EtherChannel), and then you can allow the specific VLANs to be bridged across (and another VLAN for Layer 3 connectivity). The disadvantage of this solution is that you carry the Spanning Tree state across this link. If a link fails inside DC1, the TCN would be carried to the other side as well, causing a MAC relearning event. As you are on VSS, this is less critical, as you would most likely be running MEC to the access layer switches as well. You can also filter STP on the WAN link, but then you run into a (slight) risk of a look due to some crazy failure scenario. This option is described here: http://www.cisco.com/en/US/prod/collateral/switches/ps5718/ps708/white_p aper_c11_493718.html#wp9000207 Be aware that this design is strictly proposed for dual DC designs. If you need to introduce a 3rd DC into the topology, you can't just connect it to other pair using the same solution. This would create a layer 2 loop across the DCs. We have other (slightly more complex) solutions for >2 DC designs.

But the problem is, I can?t configure eompls on a tagged interface. If I put an interface into a vrf instance the switch won?t accept the eompls statements of the ip addresses. Is this because that eompls is hard coded to use the global routing table and is there by not able to handle interfaces that are in vpn routing table. Here is my error.: aasnxc6-1(config-if)#xconnect 192.160.101.32 3300 encapsulation mpls Incompatible with ip address command on Vl3300 - command rejected. The interface belong to vpn and the ip address in the xconnect statement is the loopback address off the peer vss-router.

No, you can't do this. You will need something like the following: dc-rt1 == mpls-pe1 --- (mpls clouds) --- mpls-pe2 == dc-rt2 | | vlan3300 vlan3300 You cannot xconnect an SVI on plain-old 6500s. You can I believe do this on SPA/ES linecards, but it's expensive. You can only xconnect physical interfaces or un-routed sub-interfaces. You could use the "loopback cable into the router itself" trick, that is pretty common. dc-rt1: int Gi1/1 description connected back into Gi1/2 switchport mode trunk switchport trunk allowed vlan 3300,xxxx int Gi1/2 description received vlans from Gi1/1 xconnect ... ... ...and similarly on dc-rt2 From jckdaniels12 at gmail.com Mon Jan 18 11:57:33 2010 From: jckdaniels12 at gmail.com (jack daniels) Date: Mon, 18 Jan 2010 22:27:33 +0530 Subject: [c-nsp] MPLS - CE to CE throughput Message-ID: <8bb137f41001180857kf357958v311be8b8a40e9640@mail.gmail.com> Hi guys, I want to check the throughout in scenario CE1-----MPLS cloud ----CE2 CE1 link is 2 Mbps CE2 link is 2Mbps If CE1 pumps 2Mbps then want to check if CE2 recieves it.

No it's not. All "T" (H)WICs are for serial interfaces, which is *not* the same as a T1/E1. To use this type of (H)WIC you need a serialized interface from your leased line provider and a suitable cable. The connector types commonly used on serial interaces are V.35 and X.21.

There are two Layer 3 core switches below the two routers. The router at site B has an uplink to another transit provider and there is also a private link between the routers at site A and B. We run OSPF between all the routers/switches, also over the private link between site A and B and use "redistribute static subnets" There is iBGP running between the routers/switches and an iBGP session runs over a GRE tunnel between site A and B so that if the private link breaks, the traffic will go out over the transit providers and they will still talk to each other, etc (same AS in path) There is an issue: We have a /20 that is announced from site A and we split this up into 3 longer prefixes (/21, /22 and /24). We want to use the /24 for site B and announce the /21 and /23 from site A. However, when we remove the aggregate /20 route at site A and put a static in for the /24, it is not announced to our transit providers at site B due to rib failure.

Use commands like above "show ip ospf stat" and looks for Seq# and LSA Age to find the flapping LSA.

Totally stubby (or totally not-so-stubby if you need ASBR) should be default design, only configure no-summary if you have specific reason. Also I don't understand the need for ASBR in your NSSA - but you probably have a reason for that. > ? ? ? ?If not is there a way to get the DR in NSSA to advertise a single route back as default route? > Should we be sending each campus distribution router directly to the Core so that its the 3 hops?

We use tac_plus with accounting, no problems there. The relevant configuration is: accounting file = /var/log/tacacs-accounting.log or similar in the tac_plus.conf file, and then: aaa accounting exec [method] start-stop group tacacs+ aaa accounting commands 0 [method] start-stop group tacacs+ aaa accounting commands 15 [method] start-stop group tacacs+ aaa accounting connection [method] start-stop group tacacs+ besides you normal AAA config on the Cisco devices.

In our case (which an IPv4 BGP-free core), all aggregates are originated by our route reflectors, and they point to 192.0.2.1 and 2001:db8::1. All our routers are configured to be adjacent to Null0 (IOS) or Discard (JUNOS) for those next-hop addresses. It works!

So I wanted to know what the possible ramifications are for not setting a standby IP for an interface. My understanding is that the Primary ASA's IP is used in all cases by both primary and secondary ASAs when active and it's only the mac address that will change if the secondary ASA happens to boot and become active before the primary. Which is fairly trivial, and can be avoided with a bit of planning, so I'm not worried about this. So my thinking is, that since all traffic is going to be directed to the Primary ASAs external IP, and whatever ASA happens to be active will be able communicate on this IP, then it should be fine. And that the only thing I'm potentially losing is the ability to SSH/manage the secondary ASA from the external IP, which is completely fine in my situation. Is there another case that I'm missing? For clarification the ASAs are connected with a dedicated crossover cable for failover and state information replication. So if an interface were to fail, the other ASA should (in theory) be notified via the failover connection. Is this sound? Did I miss anything?

I'm currently using a 3550-12t for the task, with the only drawback that the cpu hits 99% load with a 5000 packets per sec./40Mbps combined throughput on the load-balanced links. The two 100Mbps uplinks never reach more than 50% utilization because the router can't handle the load. I would like to be able to handle up to 80% utilization on the 100Mbps links.

Meaning, the two ASAs will not be able to exchange 'hellos' out that interface (as the Active unit will not have an IP to send the hello to on the Standby). Thus, if connectivity is lost between the two peers - due to something other than an ASA interface failure - then failover will not be able to react to it. If you are only concerned with the ASA's outside interface failing, then this will still work (assuming the interface failure triggers the interface to transition to a down state). As the interface state will be exchanged with the peer on the failover LAN link. If you choose to configure the ASAs this way, I would also suggest you manually disable failover monitoring on the outside interface using the command: no monitor-interface outside Sincerely, David.

I also can't tell the difference. We've been using pairs of 3560E's as replacement for stacked pairs of 3750G's (non-E) and are very happy about that. They have almost the exact same specs according to the data sheets[0] apart from the stacking thing.

The best advise I could offer is understand how stackwise really works and understand packet flow. This was more of an issue for the non-E.

"something is seriously wrong there" - a 3550 should never see CPU load, even with all ports running at full speed, as the packets are forwarded in hardware (nb: don't call a 3550 a "router"...). Now, there are situations where the CPU needs to touch the packets, and then the performance goes seriously down the drain... As for "why is it CPU-switching the packets", I don't have much expertise with the 3550s - usually it's some feature (ICMP redirects, packets going in and out over the same interface, too many routes for TCAM, ...) that kills hardware forwarding. 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...

If you don't need it; skip it, maybe even look at the 295x or 296x platform unless you possibly need POE as well - the "2"s don't support it. But the ability to team/etherchannel servers via LACP and use BOTH teamed links at the same time instead of single links due to spanning-tree blocking is a great thing. It is one reason GLBP is not available on the 3750s - its not needed to get load balanced routing either. Just think of the 3750s as baby VSS-6500s or Nexus 7Ks :) From steve at ibctech.ca Wed Jan 20 08:22:10 2010 From: steve at ibctech.ca (Steve Bertrand) Date: Wed, 20 Jan 2010 08:22:10 -0500 Subject: [c-nsp] on Bogons and default bgp routes In-Reply-To: <876789291001192322t1c6c1062o2c3038c1a1628517@mail.gmail.com> References: <876789291001192322t1c6c1062o2c3038c1a1628517@mail.gmail.com> Message-ID: <4B570382.9090502@ibctech.ca> Dracul wrote: > Hi list, > > i have several BGP networks that only use default routes from a couple of > ISPs.

If you configure your network with BOGON lists, you can block that traffic inbound at your edge, and more importantly, rest assured that you won't expend resources on other networks if they don't happen to filter.

An attacker could trigger this vulnerability by sending a crafted SSH version 2 packet that may cause a new SSH connection handler process to crash. Repeated exploitation may cause each new SSH connection handler process to crash and lead to a significant amount of memory being consumed, which could introduce instability that may adversely impact other system functionality. During this event, the parent SSH daemon process will continue to function normally. Cisco has released free software updates that address this vulnerability. This advisory is posted at http://www.cisco.com/warp/public/707/cisco-sa-20100120-xr-ssh.shtml. Affected Products ================= Vulnerable Products +------------------ This vulnerability affects Cisco IOS XR systems that are running an affected version of Cisco IOS XR Software and have the SSH server feature enabled. A system with the SSH server feature enabled will have the command ssh server [v2] present in its configuration. Refer to the "Cisco IOS XR System Security Configuration Guide" at http://www.cisco.com/en/US/docs/routers/crs/software/crs_r3.9/security/configuration/guide/sc39ssh.html#wp1044523 for additional details regarding configuration of the SSH server in Cisco IOS XR Software. The SSH server can only be enabled in Cisco IOS XR Software if the "security" Package Information Envelope (PIE) is installed. Administrators can issue the show install summary command to confirm if the security PIE is installed. This command will display an active package similar to "-k9sec-" or, for example, "c12k-k9sec-3.6.1" if the security PIE is installed. Refer to the "Software Version and Fixes" section of this advisory for information on specific affected software versions. Products Confirmed Not Vulnerable +-------------------------------- SSH server implementations in Cisco IOS Software and Cisco IOS XE Software are not affected by this vulnerability. No other Cisco products are currently known to be affected by this vulnerability. Details ======= Cisco IOS XR Software is a member of the Cisco IOS Software family that uses a microkernel-based distributed operating system infrastructure. Cisco IOS XR Software runs on the Cisco CRS-1 Carrier Routing System, Cisco 12000 Series Routers, and Cisco ASR 9000 Series Aggregation Services Routers. More information on Cisco IOS XR Software is available at http://www.cisco.com/en/US/products/ps5845/index.html. The SSH protocol was developed as a secure replacement for the Telnet, FTP, rlogin, remote shell (rsh), and Remote Copy Protocol (RCP) protocols, which allow for remote device access. SSH varies from these older protocols in that it provides strong authentication and confidentiality and uses encrypted transactions. The SSH server implementation in Cisco IOS XR Software contains a vulnerability that an unauthenticated, remote user could exploit to cause a denial of service condition. The vulnerability is triggered when a new SSH handler process handles a crafted SSH version 2 packet, which may cause the process to crash. During this event, a significant amount of memory may be consumed. Repeated exploitation may impact other system functionality, depending upon the size of the available memory and the duration of attack. Although exploitation of this vulnerability does not require user authentication, the TCP three-way handshake must be completed, and some SSH protocol negotiation must occur. The SSH service will continue to function normally during an after an attack. During exploitation of this vulnerability, the system may generate the following messages: RP/0/RP1/CPU0:Jan 14 16:56:34.885 : dumper[59]: %OS-DUMPER-7-DUMP_ATTRIBUTE : Dump request with attribute 407 for process pkg/bin/sshd_child_handler RP/0/RP1/CPU0:Jan 14 16:56:34.897 : dumper[59]: %OS-DUMPER-7-SIGSEGV : Thread 1 received SIGSEGV RP/0/RP1/CPU0:Jan 14 16:56:34.901 : dumper[59]: %OS-DUMPER-7-BUS_ADRERR : Accessed BadAddr 50199000 at PC 4a280c64 RP/0/RP1/CPU0:Jan 14 16:56:34.906 : dumper[59]: %OS-DUMPER-4-CRASH_INFO : Crashed pid = 21733716 (pkg/bin/sshd_child_handler) This vulnerability is documented in Cisco bug ID CSCsu10574 and has been assigned Common Vulnerabilities and Exposures (CVE) ID CVE-2010-0137.

There are no workarounds for this vulnerability. This advisory is posted at: http://www.cisco.com/warp/public/707/cisco-sa-20100120-ipm.shtml Affected Products ================= Vulnerable Products +------------------ CiscoWorks IPM versions 2.6 and earlier for Windows operating systems are affected. Products Confirmed Not Vulnerable +-------------------------------- CiscoWorks IPM version 2.x for Sun Solaris and CiscoWorks IPM version 4.x for Windows and Solaris operating systems are not affected. No other Cisco products are currently known to be affected by this vulnerability. Details ======= CiscoWorks IPM is a troubleshooting application that gauges network response time and availability. CiscoWorks IPM is available as a component within the CiscoWorks LAN Management Solution (LMS) bundle. CiscoWorks IPM versions 2.6 and earlier for Windows contain a buffer overflow vulnerability when processing Common Object Request Broker Architecture (CORBA) GIOP requests. By sending a crafted CORBA GIOP request, a remote, unauthenticated attacker may be able to trigger the buffer overflow condition and execute arbitrary code with SYSTEM privileges on affected Windows systems. This vulnerability is documented in Cisco Bug ID CSCsv62350 and has been assigned the Common Vulnerabilities and Exposures (CVE) CVE-2010-0138. 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 CSCsv62350 - Malformed CORBA GIOP request causes crash CVSS Base Score - 10 Access Vector - Network Access Complexity - Low Authentication - None Confidentiality Impact - Complete Integrity Impact - Complete Availability Impact - Complete CVSS Temporal Score - 9.5 Exploitability - Functional Remediation Level - Unavailable Report Confidence - Confirmed Impact ====== Successful exploitation of the vulnerability may result in the ability to execute arbitrary code with SYSTEM privileges on affected Windows systems. Software Versions and Fixes =========================== Ciscoworks IPM versions 2.6 and earlier for Windows contain a vulnerable third-party component that is no longer supported. Cisco is unable to provide updated software for affected CiscoWorks versions. Consult the "Obtaining Fixed Software" section of this advisory for instructions on how to address vulnerable systems. Workarounds =========== There are no workarounds for this vulnerability. It is possible to mitigate this vulnerability by restricting network access to TCP ports on an affected Windows system running IPM versions 2.6 and earlier to trusted systems. Additional mitigation techniques that can be deployed on Cisco devices within the network are available in the Cisco Applied Mitigation Bulletin companion document for this advisory: http://www.cisco.com/warp/public/707/cisco-amb-20100120-ipm.shtml Obtaining Fixed Software ======================== Ciscoworks IPM versions 2.6 and earlier for Windows contain a vulnerable third-party component that is no longer supported. Cisco is unable to provide updated software for affected CiscoWorks versions. Customers with active software licenses for the IPM component of CiscoWorks versions 2.6 and earlier for Windows should send email to the following address for instructions on migrating to non-vulnerable software: ipm-corba-fix at cisco.com Exploitation and Public Announcements ===================================== The Cisco PSIRT is not aware of any public announcements or malicious use of the vulnerability described in this advisory.

I was wondering if there was some hardware differences (like > > CAM table size, ethernet input/output buffer sizes), etc... Is the packet buffering on the -Es significantly better than on the non-Es? It would seem that the buffering capabilities of a non-E are at best limited, based on my experience - granted we have bursty server loads that we were attempting to condense down into 4-port etherchannels, but I would have expected the 3560Gs to do better than they did. I suppose it's possible that if I split the ports up amongst the ASICs better it might be better, but it seemed like there was only one TX queue buffer for the entire switch, which if you did "mls qos" you could split up some but you still had a limited choke that everything went through. I really don't want to go buy a -E to find out. I never could get an answer from cisco as to the actual design of the internals of the 3560/3750s. Is the information around anywhere?

Compare this to two seperate switches and RSTP, with which can do almost "zero touch" upgrades. In my eyes StackWise stacks are in all aspects to be treated as a single unit. When looking at "single points of failure" I consider a 3750 stack (E or non-E) a single unit no matter how many members in the stack. The VSS might have the same problem, haven't touched it. -- Peter From bitkraft at gmail.com Wed Jan 20 14:27:28 2010 From: bitkraft at gmail.com (Brian Spade) Date: Wed, 20 Jan 2010 11:27:28 -0800 Subject: [c-nsp] Differences between 3750-E and 3560-E switches In-Reply-To: References: <483E6B0272B0284BA86D7596C40D29F9E2BC79F5FE@PUR-EXCH07.ox.com> Message-ID: <505b616c1001201127k5f797092gc4bb49b959241767@mail.gmail.com> If you use WCCP (i.e., wan acceleration/WAAS), the 3750-E supports denies in the redirect ACL whereas the 3560-E does not.

Another approach (but only relatively new IOS versions) would be to use the EEM SNMP Notification event detector. This would allow you to catch specific traps and block them on the router (or modify them to a different event). In older IOS versions the same can be accomplished for Syslog, so if you can turn off SNMP traps and use Syslog events, you can accomplish this on most IOS versions.

The main goals are 1) separate the branches in general but allow the firewalladministrator to route between the branches so the customer is able to control his internal traffic as well as his internet traffic 2) provide redundancy for all of our components At the moment we're providing only ordinary Layer3-MPLS VPNs but in this case this isn't enough - unless if we plan to implement a dedicated VRF for each branch.

HD VRF will assign a different VRF for upstream and downstream traffic, so packets entering the LNS from the branch will only see the Hub routes, and not the other branches' routes. check out http://www.cisco.com/en/US/docs/ios/12_3/feature/guide/ghdpvrf.html oli From md at bts.sk Thu Jan 21 02:15:35 2010 From: md at bts.sk (=?UTF-8?Q?Marian_=C4=8Eurkovi=C4=8D?=) Date: Thu, 21 Jan 2010 08:15:35 +0100 Subject: [c-nsp] Differences between 3750-E and 3560-E switches In-Reply-To: <5A69C25361FED34F83ABF05F5047524507F05C97@wally.walleyetrading.net> References: <5A69C25361FED34F83ABF05F5047524507F05C97@wally.walleyetrading.net> Message-ID: <20100121070932.M18969@bts.sk> On Wed, 20 Jan 2010 10:17:39 -0600, Jeff Bacon wrote > > > I've read through the data sheets, and I also can't see any > signficant > > > differences.

Jep, that might be a way, even not "beautiful" for us. We're moving this customer from an ugly partial/fully IPSec-tunnel meshed setup with many firewalls and IPSec tunnels and I don't want to implement and manage a bunch of IPSec tunnels again. I thought already about some pseudowire or other basic tunnel service (like GRE) from the CPEs to the firewall but I have to deal with redundant tunnel-endpoints as well - the tunneling setup must have an fail-over/redundancy concept. That makes me think about implementing 2 tunnels from each CPE on to 2 additional tunnel-endpoints (between RTR and FW) and configure a basic routing protokoll on top of the tunnels... Hm, that "is" an solution but I'll check further if I have other options before going that way.

In the other hand, Radiator looks to be great too. The paid support behind gives me some relax. I dont need to put focus of software bugs, integration problems -if it is supported, it must work- and all those things. The global idea is to cover the technical goals, as well, very small time to deploy it and put it into production. If freeradius installation+configuration+tuning+web ui+read the oreilly book is more than 2 weeks... it is not acceptable for me -we don't have free physical time for that-, we will go for radiator. And, maybe in the future we could move to freeradius doing previously a proof of concept. For me, right now, I think it could be faster -with the same features and results- the Radiator solution.

Hardware: - 6509 with SUP720-3BXL on both ends - SXF15a - Uptime: 46 weeks Problem: - OSPF (for the loopback between cores) and BGP (mostly customers whom we send the full table) going up and down all the time: %OSPF-5-ADJCHG: Process 1, Nbr x.x.x.130 on TenGigabitEthernet4/1 from FULL to DOWN, Neighbor Down: Dead timer expired %OSPF-5-ADJCHG: Process 1, Nbr x.x.x.131 on TenGigabitEthernet9/1 from LOADING to FULL, Loading Done %BGP-5-ADJCHANGE: neighbor y.y.y.14 Down BGP Notification sent %BGP-3-NOTIFICATION: sent to neighbor y.y.y.14 4/0 (hold time expired) 0 bytes %BGP-5-ADJCHANGE: neighbor y.y.y.14 Up This keeps going on for several hours, and suddenly it stabilizes itself. Furthermore I use cacti to generate graphs from the core router via SNMP. I have one VLAN that has around 15 GBPS traffic at peak times, and as soon as I hit more than 15 GBPS, no more graphs are drawn, core router console becomes rather unresponsive and OSPF starts to behave strangely. What I can rule out is the fiber capacity. I have multiple circuits and different paths and operators. The OSPF issue happens on all circuits, not just a specific one. No 10 GE link is used more than 60%. In fact, traffic from inside my backbone to any place outside remains unaffected (thank God), but the core router itself is pretty useless. Pinging the core's loopback or any ip loaded on that box results in a 40-60% packet loss. CPU usage is not high, it's stable. No unusual processes, just IP Input and BGP Scanner. More than 50% memory is still free at that time. I've had this many times recently, but it really just happens when my core goes beyond +- 15 GBPS of traffic (outbound). We've been below 15 GBPS for 2 years and it never happaned at that time. Now all this mess happens almost daily, rendering important billing graphs useless and annoying full table BGP customers. Is this a memory issue, due to the router's long uptime? Would reloading the router help in this case? That's the last thing I would want to do, but if it helps...
