To resolve high CPU utilization on Cisco IOS XE devices, follow these steps:
- Identify the Cause: Use the show process cpu sorted and show platform punt statistics commands to determine which processes or packets are consuming the most CPU resources.
- Check for Network Issues: Look for network problems such as broadcast storms or high traffic volumes that could be overwhelming the CPU.
- Optimize Configurations: Adjust configurations to reduce CPU load, such as limiting SNMP polling rates or disabling unnecessary services.
- Update Firmware: Ensure your device is running the latest firmware, as updates often include performance improvements and bug fixes.
1. Implement Control Plane Policing (CoPP): Use CoPP to limit the amount of control plane traffic allowed into the CPU. - Monitor Regularly: Continuously monitor CPU utilization and address issues promptly to prevent them from escalating.
