Cat 4006 Sup CPU running high

[mike.bradley]

I'm trying to fix a condition where my cat sups CPUs are running 80% and higher all day. I have read that having POE line cards adds to the cpu overhead. Should turning off inlinepower device detection lessen the load on the cpu? id set port inlinepower mod/port off

Hi

These 2 links can be helpful to understand the main reason for the spike in cpu utilisation which can help u out in troubleshooting the same.

You can find out the process which takes out the max of the CPU cycle,once you are done with the findings about the process you can start off proceeding with containing the same.

POE cards should not cause CPU utilization this high. Attach outputs of

sh mod

sh proc cpu | exc 0.0

sh platform health

I've attached the output from show proc cpu and show mod. The show platform isn't supported.
