We need to know how you configured snmp Configuration for this router. Normally
this high CPU load corresponds with the Configuration polling Interval. Set
number of route entries to 50 or 100.
There's been a lot of discussion about this topic last year, you may look up
the archives.
You may debug snmp on the cisco-router to see which mib values are transferred,
but it will probably crash the router...

Strange CPU usage on a CISCO Router.
I poll just 1 time a minute to recive just one MIB value (CPUbusy)
to check the CPU usage of the router.
Nearly periodically every half houre the CPU usage go up to 70%.
Once or twice a day the CPU usage go up to 99% - 100% for 1 houre.
in this time, the router shows me 85% of CPU usage go to IP SNMP Process.
Its a CISCO 2500 with IOS 11.3
Is it possible that NetView with one Request a minute is resonsible
for this??? I cant belive. But ther is no other machine using
SNMP to acces the router. And the SNMP process thakes 85% of CPU.
I check the interfaces for SNMP trafic. It is close to zero.
What can I do????
