Mac-Flapping Errors not showing on 'Show Log"

[leafar1988]

I am not seeing Mac-Flap errors when I do a "show log" on a 4507. We had a mac flapping around and I was wondering why I didnt see any messages showing for it, it was going between a switch port and a port channel.

We have "snmp-server enable traps mac-notification change move threshold" enabled. It is also pointing to the correct SNMP server.

Is there another command I need to be able to see mac address flapping under the "show log" command? Or is the command I put above enough?

Thanks.

Hi,

Have you enabled logging to buffer and at what  level? if buffer logging is not enabled try adding  "logging buffered 16384 informational" to your config

Thanks
