      -I've discovered a bug where MAC address 00:00:00:00:00:00 is getting rejected on all LACP LAG ports. This causes issue with inter-networking VLANs between PFSense and Cisco SG switches. If I change any VLAN mac address from 00:00:00:00:00:00 to 00:00:00:00:00:01 then everything works properly. Below are links to similar issues with Cisco and Mac: 00:00:00:00:00:00

      -Also when you modify a VLAN Interface that has the MAC: 00:00:00:00:00:00 it removes the static MAC we've set to work around the problem.

      Is anyone aware of these issues?
