Hi,

if you  post output of "sh process cpu | exc 0.00 "  will be helpful to know which process

Hey Dmitry,

Most likely in 'show process cpu sorted' you will see Cat4k Mgmt HiPri or Cat4k Mgmt LoPri using the most cycles. 'show platform health' allows you to look deeper into the causes of CPU utilisation in those processes on Catalyst 4500 switches. The following document will be useful:
