Example: Verifying the Problem and Cause for High CPU Utilization
To determine if high CPU utilization is a problem, enter the show processes cpu sorted privileged EXEC
command. Note the underlined information in the first line of the output example.
Switch# show processes cpu sorted
CPU utilization for five seconds: 8%/0%; one minute: 7%; five minutes: 8%

<output truncated>
This example shows normal CPU utilization. The output shows that utilization for the last 5 seconds is 8%/0%,
which has this meaning:
• The total CPU utilization is 8 percent, including both time running Cisco IOS processes and time spent
handling interrupts.
• The time spent handling interrupts is zero percent.
