The MAC address was not set correctly on the lagg interface so all outgoing frames have the src of 00:00:00:00:00:00. This still worked in a lot of situations as the machine replied with the correct arp address and the configured laggports had the correct MAC. Most people didnt see a problem which is why this slipped through. tcpdump on another host with the -e flag and see what the src mac is. Andrew
