I have a Cisco 2851 router which placed on one of our company node. Currently it's handling 80M of traffic. Recently ?I have monitor increased in CPU due to SNMP. Appreciate if someone can help me with this ??
looking at your process stats of the 84% util, 64% of that is due to CPU interupts. The SNMP process being high up the list is a red herring. You should investigate what traffic is being sent to the CPU for processing.
Following the steps in these documents should aid in troubleshooting:
Taking a look you can see that the OIDs being polled the most are:
09:16:25 LK Nov 10 2014 548 ipAddrEntry.2 09:16:23 LK Nov 10 2014 528 ifType
So you can either check the monitoring tool using that community and increase the polling intervals or set a view to those OIDs.
Those are huge OIDs so it is expected that being polled a lot cause high cpu, on this case it is weird as they only have 5%, that is not high cpu at all, you can check the show process cpu history, I think about a bug showing wrong information on the processes.
