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. High CPU utilization on Cisco switches can lead to degraded network performance, packet loss, and even switch failures. Identifying and troubleshooting the root cause of high CPU usage is essential for maintaining a healthy network. In this article. I noticed that after having VLANs, ClearPass, spanning tree, and all other settings configured, that CPU util was just sitting at or above 85% on all these switches. I updated firmware to the latest version on all of them, but that didn't help. Problem analysis process 1. According to the switch logs, after searching for related processes, we can find that the. my switch core has high CPU usage every 3 minutes, switch logs attached.
