How can I tell which CPU is high on a Cisco switch?
To determine switch CPU utilization, enter the show processes cpu sorted privileged EXEC command. The output shows how busy the CPU has been in the past 5 seconds, the past 1 minute, and the past 5 minutes. The output also shows the utilization percentage that each system process has used in these periods.

Why is my Cisco Catalyst 3850 using so much CPU?
The troubleshoot and verification process in this section can be broadly used for high CPU usage due to interrupts. The show process cpu command naturally displays how the CPU currently looks. Notice that the Cisco Catalyst 3850 Series Swtich uses four cores, and you see the CPU usage listed for all four cores:
Which is Cisco IOS image has higher CPU utilization?
The Catalyst 2960 switch running the LAN base image has a smaller number of active processes than a stack of Catalyst 3750 switches. In general, the more features in the Cisco IOS image, the more system processes. These sections tell how to identify high CPU utilization and determine if it is a problem:
Why is the CPU usage on my 3850 so high?
I have multiple 3850’s running 16.3.6 with no issue but in one case the IOSD ipc task is causing the CPU to run at a constant 70 to 90 percent. I am monitoring this device’s CPU with Prime Infrastructure 3.4 and below is a copy of the command “show process cpu | ex 0.0” Any help would be much appreciated.
