Not really - I just want to get this up and running, getting the provider to
change their setting means waiting for them to do it. :-)

The origin of the route is unknown or learned in some other way. An origin
of incomplete occurs when a route is redistributed into BGP.

Hi,
Per linecard CPU monitoring is tricky.
This is because the SNMP string per liecard changes at every reboot.
(or even a linecard reload)

Content-Type: text/plain; charset="us-ascii"
Does anybody know what the performance limits of a 3662 with regards to SLB
are?
I basically need to know how many simultaneous TCP (HTTP) sessions it can
dispatch in NAT mode - I've got a requirement where a 3662 (of which I have a
few) may be adequate, however I want to try and find out before I need to go
and buy a CSS at zero notice.
I've had a look at the Cisco site, and their documentation is woefully out of
date with regards this functionality - only the feature navigator knows the
3660 can support SLB - the configuration documentation cuts off at 6500/7600
and 7200.
Thanks

Any idea how much traffic either in pps or mb/s you were thinking? How
many users behind it?
I haven't ran a lot of it on a 3662 but if you provide a few numbers I
could provide "best guestimate"..;)

Hello,
we had a problem this morning where the config of a customer router had not
been saved, and a power outage occurred after which the router rebooted with
an older and incorrect config. Shame on us.
What we would like to do now is to write a script that gets running and
startup configs of each device, diffs them, and sends a warning if
differences are seen.
We already have a script that gets the running configs via a SNMP-triggered
writenet (enterprises.cisco.local.lsystem.writeNet from OLD-CISCO-SYS-MIB).
How do I get the running config with SNMP ? I have found
enterprises.cisco.local.lflash.flashToNet in OLD-CISCO-FLASH-MIB, but it
does not work on my routers:
[vdk ~]$ snmpwalk -c private -v 2c router 1.3.6.1.4.1.9.2.10
SNMPv2-SMI::enterprises.9.2.10 = No Such Object available on this agent at
this OID
[vdk ~]$
"router" is a 7206VXR running 12.2(25)S4.
Anyone?
Vincent

If its just this one router download Kiwi Cat tools freeware version and it
does it all for you.

I'd suspect the worst case is 10k concurrent sessions - we're running rather
lower than that just now.
In terms of PPS, given that all we'll be doing from behind it is HTTP
redirects, that translates to around 10kpps assuming standard ethernet packet
sizes. I know this is close to the process switched limit for the 3660
(12kpps) but I've no idea how that scales against SLB usage.
At the moment we're doing closer to 3k concurrent sessions as a peak.

Yeah... I think it'll kill that router... Just my opinion
The only comparitive I can provide is a 3662 I have in production right
now running IOS SLB with NAT and it's only pushing about 3000pps or 12.5
Mb/s and the CPU sits around the 45-55% range....
Hope that helps...
