802.1Q VLAN
The 802.1Q VLAN protocol on the access point logically separates traffic on the same
physical network. See
.
•
Untagged VLAN
. When this 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 will be 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 will be accepted.
Note:
The
Untagged VLAN
check box should not be selected 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 and 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 and switches on your network have not yet
been configured with the corresponding VLANs.
•
Management VLAN. 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 must be tagged.
