Port Default VID and Priority
When the port VID table is selected (PVIDnVLAN=1 of the
VLAN Command Register
the default VID for the port and bits 14:12 specify the default priority. All
other bits of this field are reserved. These bits are used when a packet is
received without a VLAN tag or with a NULL VLAN ID. The default VID is
also used when the
also used when no other priority choice is selected. By default, the VID for
all three ports is 1 and the priority for all three ports is 0.

Values of 0 and FFFh should not be used since they are special
VLAN IDs per the IEEE 802.3Q specification.
Member Port 2
Indicates the configuration of Port 2 for this VLAN entry.
1 = Member - Packets with a VID that matches this entry
are allowed on ingress. The port is a member of the
broadcast domain on egress.
0 = Not a Member - Packets with a VID that matches this
entry are filtered on ingress unless the
bit in the
(SWE_ADMT_N_MEMBER)
not a member of the broadcast domain on egress.
Un-Tag Port 2
When this bit is set, packets with a VID that matches this
entry will have their tag removed when re-transmitted on
Port 2 when it is designated as a Hybrid port via the
Manager Egress Port Type Register
(BM_EGRSS_PORT_TYPE).
Member Port 1
See description for Member Port 2.
Un-Tag Port 1
See description for Un-Tag Port 2.
Member Port 0
See description for Member Port 2.
Un-Tag Port 0
See description for Un-Tag Port 2.
VID
These bits specify the VLAN ID associated with this VLAN
entry.
To disable a VLAN entry, a value of 0 should be used.

802.1Q VLAN Disable
A value of 0 is considered a NULL VLAN and
should not normally be used other than to
disable a VLAN entry.
A value of 3FFh is considered reserved by IEEE
802.1Q and should not be used.
