Filter Control
The wireless bridge can employ VLAN tagging support and network traffic frame
filtering to control access to network resources and increase security.
Native VLAN ID – The VLAN ID assigned to wireless clients that are not assigned to
a specific VLAN by RADIUS server configuration. (Range: 1-64)
VLAN – Enables or disables VLAN tagging support on the wireless bridge (changing
the VLAN status forces a system reboot). When VLAN support is enabled, the
wireless bridge tags traffic passing to the wired network with the assigned VLAN ID
associated with each client on the RADIUS server or the configured native VLAN ID.
Traffic received from the wired network must also be tagged with a known VLAN ID.
Received traffic that has an unknown VLAN ID or no VLAN tag is dropped. When
VLAN support is disabled, the wireless bridge does not tag traffic passing to the
wired network and ignores the VLAN tags on any received frames.
Note: Before enabling VLANs on the
wireless bridge
, you must configure the connected
LAN switch port to accept tagged VLAN packets with the
wireless bridge
’s native
VLAN ID. Otherwise, connectivity to the
wireless bridge
will be lost when you
enable the VLAN feature.
Up to 64 VLAN IDs can be mapped to specific wireless clients, allowing users to
remain within the same VLAN as they move around a campus site. This feature can
