on MAC Address 0100.5e7f.fffe

*Oct 2 17:24:47: %SNMP-CLUSTER_MEMBER_1-3-CPUHOG: Processing GetNext of dot1dTp

FdbEntry.1.0.224.41.133.127.9

*Oct 2 17:24:47: %SYS-CLUSTER_MEMBER_1-3-CPUHOG: Task ran for 5620 msec (14204/

255), process = IP SNMP, PC = 801D1C9C.

-Traceback= 801D1CA4 80076610

Cisco.com has an error message decoder tool.

It is located at

This should help for most messages.

The error message you pasted is a CPUHOG error message. Basically the SNMP process was using up too much CPU processor time. Find out what those MIBs do and why the collection of that info could

hold up the CPU.

What Causes %SYS-3-CPUHOG Messages?
