Flapping host on 4912G

Hi Folks

Can anyone point me in the right direction to start troubleshooting the messages below from our 4912G switch.

Cheers

Mike

Solved I think - the MAC address 02:01:00:00:00:00 is a virtual MAC address used by the Windows network load balancing service for broadcasts. We're checking our server boxes to see which ones have this enabled.
