Hi,

TO add,Check couple of things.

1. if you are running HSRP, check for the stability of the same.

2. If you have spanning tree configured, check what is the version number and if it is increasing rapidly, check for any loops.

3. Any broadcast storms

Attach the o/ps of these commands.

sh process cpu sorted

sh logging

Thanks and Regards,
