Can your help me giving me some clue to what may be the cause of higher CPU usage and how I can correct IOS version of the devices is 122 (53) SG1, I upload attach file with the show tech-support of the equipmente
When the same MAC addresses are learned and aged out on different VLANs, the Cat4k Mgmt LoPri process will cause CPU utilization to increase. This does not impact local data switching performance because the LoPri process is of low priority with limited access to the CPU.
High CPU due to Mgmt LoPri process, MAC addresses being added/deleted
Symptom: A Catalyst 4500 switch might experience high CPU utilization due to the Cat4k Mgmt LoPri process and the K2CpuMan and K2L2 Address Table reviews (show platform health. High CPU utilization does not impact the traffic switched in hardware.
Conditions: The problem is seen when a large MAC address table exists and when the switch is frequently relearning MAC addresses on multiple VLANs. Enabling service internal followed by debug platform log feature k2l2addresstable will show output similar to the following. Do not enable these commands on a production switch unless instructed by Cisco TAC.
