WG103 ProSafe 802.11g Wireless Access Point Reference Manual
5-4 Advanced Configuration
v1.0, February 2009
:
3. Make selections from the following options:
• Untagged VLAN . When checked, this option allows one VLAN to be configured as an
“untagged VLAN.” When the wireless access point sends frames associated with the
untagged VLAN out the LAN (Ethernet) interface, those frames will be untagged. When
the wireless access point receives untagged traffic from the LAN (Ethernet) interface,
those frames are assigned to the untagged VLAN.
When unchecked, the wireless access point tags all outgoing LAN (Ethernet) frames, and
accepts only incoming frames that are tagged with known VLAN IDs.
• Management VLAN. Management VLANs are used for managing traffic (Telnet, SNMP, and
HTTP) to and from the wireless access point.
Frames belonging to the Management VLAN are not given any 802.1Q header when sent over
the trunk. If a port is in a single VLAN, it can be untagged. But if the port needs to be a
member of multiple VLANs, it must be tagged.
4. Click Apply to save your settings.

Note: The Untagged VLAN checkbox should be unchecked only if the hubs or
switches on your LAN support the VLAN (802.1Q) standard. Likewise,
the Untagged VLAN value should be changed only if the hubs or switches
on your LAN support the VLAN (802.1Q) standard. Changing either of
these values will result in a loss of IP connectivity if the hubs or switches
on your network have not yet been configured with the corresponding
VLANs.
