Processor high Utilization

[biplobkhan]

Hi

My client using 3845 as a core router . 200 number of branch are connected through 6 ISP.

Some of days average process shows 90 % . Max time 50 %.

In the morning when Branch location are off then time also high utilization.

High utilization is not continue after intervals of time or periodic time its goes to high.

have any solution for that ?. before once 3845 is crash for that. another is ready for replacee.

We test another device like core switches for observation CPU rate.

Regards

Hi,

When the CPU untilization is high, you can run the command 'show proc cpu sorted' and see what process is using more cpu. Also, check the below link- general approach to t-shooting high CPU on cisco routers.
