802.1Q VLAN

The 802.1Q VLAN protocol on the access point logically separates traffic on the same
physical network. Select Configuration > System > General to display the following screen:

Untagged VLANs

When the Untagged VLAN check box is selected, one VLAN can be configured as an
untagged VLAN. When the access point sends frames associated with the untagged VLAN
out the LAN (Ethernet) interface, those frames are untagged. When the access point
receives untagged traffic from the LAN (Ethernet) interface, those frames are assigned to the
untagged VLAN.
If this check box is not selected, the access point tags all outgoing LAN (Ethernet) frames.
Only incoming frames tagged with known VLAN IDs are accepted.
You only need to clear the Untagged VLAN check box 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 and switches on your LAN support the VLAN (802.1Q) standard.
Changing either of these values resulst in a loss of IP connectivity if the hubs and switches
on your network have not yet been configured with the corresponding VLANs.

Management VLANs

Management VLANs are used for managing traffic (Telnet, SNMP, and HTTP) to and from the
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 has to be tagged.
