Hi,  The show processes cpu



 The show processes cpu output shows that there are two processes that use the CPU— Cat4k Mgmt HiPri and Cat4k Mgmt LoPri . These two processes aggregate multiple platform-specific processes which perform the essential management functions on the Catalyst 4500. These processes process control plane as well as data packets that need to be software-switched or processed.

In order to see which of the platform-specific processes use the CPU under the context of Cat4k Mgmt HiPri and Cat4k Mgmt LoPri , issue the show platform health command and check what is the process exceeding the target, once that has been identify you can move forward.
