>Description:
as you can see on vlan408 there is arp reply messages from localhost
but on igb0 there is arp replay traffic.
>How-To-Repeat:
on the switch turn off port where igb0 is connected, reboot system, leave system in this state for two days, after two days trun on port:
# ifconfig igb0
igb0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500

# ifconfig vlan408
