How To Troubleshoot A High Cpu Utilization Problem In A Router? |

Answer» This symptom is the sign of abnormal functionality in a router. FIRST we should know the exact reason for INCREASED CPU utilization, and we can use “show processes cpu ,” “show INTERFACE stat” COMMANDS to check the process utilizations. It could be due to high traffic FLOW (congestion), complex ACL or VPN deployments, ARP/TCP issues etc. This symptom is the sign of abnormal functionality in a router.
