Hi, AHTOH,

Suggest you to run "top" output more than 40 seconds and then collect "show cpu-monitoring", also see "show log" from switch.

ŠŠ½Ń‚Š¾Š½,

Please run the "top" output for some time and see if any other process is high.
Like SNMP or the bcmrx.

If the snmp process (snmpmaster and subagent) process is high then it indicates a continuous polling is happening and that indirectly affects the process VLAN .

In case if bcmrx is high that indicates high number of packets are carried to the CPU which needs further investigation.

If none of the other process is high do you remember doing any configuration changes or executed any commands which results in the VLAN process spike?
