Note:
The system requires a reboot after the “vlan enable” command. If the system is not rebooted, the webUI will
not display the VLAN configuration and the CLI will not execute VLAN commands.
Note:
VLAN configuration commands have changed with the 1.3.0 firmware release. Older commands are
deprecated and will be removed in a future release.

The T2 Switch is a VLAN switch. The WallPlate is also a VLAN switch. Therefore, be certain that packets traversing
the DSL links between the T2 Switch and the WallPlate are always TAGGED.
PVID
In the 802.1Q standard, each port is assigned a PVID. This is the default VLAN ID
assigned to
untagged packets
received (ingress) on that port. The PVID is sometimes
called the port Native VLAN. By default, all ports are assigned VLAN 1.
Tagged
T2 will optionally tag packets when transmitting (egress) on the port. Set the port as a
tagged member of the VLAN by using the
vlan membership egress
command.
On the T2 Switch, the tag mode of a packet is determined PER VLAN, not per port. By
comparison, the Cisco IOS only has a per port setting for tagging. This allows the T2 to
support complex VLAN configurations not possible on other switches.
On the m2 WallPlate, the tag mode of a packet is determined PER PORT, similar to the
Cisco IOS “trunk” mode.
Untagged
T2 will optionally transmit (egress) packets without an 802.1Q VLAN tag. Use
Untagged packets on any port that is connected to a non-VLAN aware device. For
example; if a PC is connected to the WallPlate ports, packets will be untagged. This is
similar to the Cisco IOS “access” mode of a switchport.
