Hello vishwa,

if you have multiple switches:

first you need to break the loop (if any)

if you can still access the device concentrate on inter-switch links and shut down the redundant one (if any).

else if your switch is standalone:

But if the high cpu is caused by high port utilization this can be unavoidable.

What platform is it ?

Some time ago in another thread a collegue noticed high cpu usage on C2600 even if broadcast traffic had to be discarded by broadcast storm control

Hope to help

Giuseppe
