Cluster Members with the fixed source MAC address
02:00:00:00:00:mem_id are forwarding cluster correction packets.
When you run more then one cluster in the same segment (sk25977), port flapping can occur because two different Cluster Members have the same correction MAC address.
02:00:00:00:00:00 - The correction packets from member 1 (on both clusters)
02:00:00:00:00:01 - The correction packets from member 2 (on both clusters)
