Table 3: Troubleshooting CPU Utilization Problems Troubleshooting the Software Configuration Example: Verifying the Problem and Cause for High CPU Utilization Type of Problem Cause Corrective Action Interrupt percentage value is almost as high as total CPU utilization value. The CPU is receiving too many packets from the network. Determine the source of the network packet. Stop the flow, or change the switch configuration. See the section on “Analyzing Network Traffic.” Total CPU utilization is greater than 50% with minimal time spent on interrupts. One or more Cisco IOS process is consuming too much CPU time. This is usually triggered by an event that activated the process.
Identify the unusual event, and troubleshoot the root cause. See the section on “Debugging Active Processes.” Troubleshooting the Software Configuration 24
