High CPU Load on Cisco 2621 router

[chris.lau]

Hi All,

My 2621 router constantly showing 90% CPU load. The show proc cpu command didn't tell me which process used lots of the cpu resources. Can I know whether there is any other way to check it?

Hi

Can you post the output of show process cpu ?

you can also check out for CEF whether CEF is enabled or not.

once CEF check is over you can enable netflow and find out whether you have worms/virus in your network..

In fact the most common cause of high cpu load is abnormal traffic, so spremkumar's answer is correct, didn't deserve low rating so I have rated this to balance.
