Description (partial)

Symptom:
ARP reply packets that are sent with switchport MAC address as destination address are flooded back to network by the switch. Ideally, such packets should be consumed by the switch.

Conditions:
The switchport MAC address is used as source MAC and sender MAC when ARP probes are sent by IPDT feature. The replies to these packets will cause this issue.
