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.
Thanks
