RE: [nv-l] Cisco 2500 routers and NetView

In that case, reducing the number of routing table entries pulled from the default of 800 to, say, 2, after initial discovery is done will help prevent swamping them during demandpolls and regular configuration polling. That is done in Options... SNMP.

Cordially,

The issue is the CPU performance in the 2500. There are some suggestions floating around in the archives about trimming down the amount of SNMP data that NetView asks for. Remember that SNMP is the lowest priority function in the Cisco IOS. Retries/timeouts will help but trimming down the SNMP queries is probably necessary.

We have several 2500 series routers and I also resolved the issue by increasing the retry and the retry intervals.

I experienced the same problem about 2 years ago before we replaced our 2500 series routers.  We had approx. 700 2500 series routers of various flavors deployed though out our WAN.  Many of these devices were running out of memory during demand polls etc.  In order combat our polling issues, the only thing we could do was increase the retry and lower the timeout values.

I have a lot of old Cisco 25xx routers in my network. There are plans to
replace these older devices this year but not until much later in the year.
I poll all of my routers via SNMP.  I see a lot of missed SNMP queries of
these routers. This causes NetView to report the router down when it is in
fact still reachable.  I was wondering if anyone on the list has
experienced this of has any suggestions on how to better monitor older
Cisco routers.
