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. Troubleshooting the Software Configuration Example: Verifying the Problem and Cause for High CPU Utilization Command Purpose show onboard switch switch-number message Device# show onboard switch 1 message Displays the hardware-related messages generated by a standalone switch or the specified stack members.
show onboard switch switch-number counter Device# show onboard switch 1 counter Displays the counter information on a standalone switch or the specified stack members. show onboard switch switch-number temperature Device# show onboard switch 1 temperature Displays the temperature of a standalone switch or the specified switch stack members. show onboard switch switch-number uptime Device# show onboard switch 1 uptime Displays the time when a standalone switch or the specified stack members start, the reason the standalone switch or specified stack members restart, and the length of time that the standalone switch or specified stack members have been running since they last restarted.
show onboard switch switch-number voltage Device# show onboard switch 1 voltage Displays the system voltages of a standalone switch or the specified stack members. show onboard switch switch-number status Device# show onboard switch 1 status Displays the status of a standalone switch or the specified stack members.
