Quick Answer: To check CPU utilization on a Cisco switch, use the command “show processes cpu” in the CLI. This displays current CPU load, CPU usage history, and process-specific details, aiding in network performance troubleshooting. The CPU becomes too busy when either an IOS process consumes too much CPU time or the CPU receives too many packets from the switching hardware. When either of these two CPU consumers requires the CPU resource to the detriment of the other, then the CPU is too busy. For instance the CPU is.
