VLANs – Allows you to add and delete VLANs from the VLAN table in the manner
described in Section 4.3. Click the 'New Entry' link to add a VLAN to the table. The
‗Add Switch VLAN Screen‘ appears:
Figure 9-43: Add Switch VLAN
VLAN ID – The VLAN identifier of VLAN.
Port – Each port can either be ‗T‘ tagged, ‗U‘ untagged or ‗–‗ not member of this
VLAN.
 ‗T‘ means that outgoing packets will be tagged with the VLAN identifier.
 ‗U‘ means that outgoing packets will not be tagged.
 ‗–‗ means that the port is not member of the VLAN.
Note: Before marking the Trunk port with a ‘T’ (tagged), make sure that you have al-
ready created a VLAN interface on the LAN side of the router. The procedure to cre-
ate a VLAN interface on the router is described in section 9.4.11.
If you fail to do so, you might loose connectivity to the Watson management. If you
loose connection to the Web-based management you can restore the factory default
configuration. The procedure is described in the Watson SHDSL Router Manual [1].
9.4.4.5 VLAN Example
A VLAN configuration example is shown in Figure 9-44:
1. Two VLANs are configured: VLAN 100 and VLAN 200.
 Ports 1, 2, 3 and 4 are members of VLAN 100.
 Ports 5, 6, 7 and 8 are members of VLAN 200.
 The Trunk port is member of both VLANs: VLAN 100 and VLAN 200.
2. For untagged packets the default VLAN ID for the port is used to determine
VLAN membership.
 Ports 1, 2, 3 and 4 and the Trunk port have a default VLAN ID 100.
 Ports 5, 6, 7 and 8 have the default VLAN ID 200.
