Byte.bit Description
79.7
1: The switch will replace a NULL VID with a port VID (12 bits)
0: No replacement for a NULL VID
79.6
1: If the received packets are tagged, the switch will discard packets with a
VID that does not match the ingress port default VID, which is indexed by
port 8’s “Port-based VLAN index”
0: No packets will be dropped

VLAN Membership’, which may be defined in one of the registers ‘VLAN
ID [A] Membership’ to ‘VLAN ID [I] Membership’. Port 8 can only
communicate within the membership. This register also indexes to a default
Port VID (PVID) for each port. The PVID is used in tag insertion and
filtering if the tagged VID is not the same as the PVID.
79.0
This register along with byte 78.7~78.0 forms a 9-bit field that specifies
which ports are members of the VLAN. If a destination address look up fails,
packets associated with this VLAN will be forwarded to ports specified in
this field. E.g., 1 0000 0001 means port 8 and 0 are in this VLAN.
