3560 CPU utilization constantly showing 87%

hello, we are using a 3560 switch and the cpu utilization is constantly showing 87 %.

This switch is doing routing and leased lines are connected to service providers.

Is there any trouble shooting steps that can be done?

 

Regards,

Shiva

Inayath's document is nice, and in it he mentions show tcam utilization.  If your TCAM overlfows, some packet forwarding will be done in CPU.  So, that's an important check; insure you're using the most suitable SDM template.

Pfft!  Upgrade your IOS to 12.2(55)SE9 and, about 30 minutes later, check the status of your CPU.
