Cisco BR1400 Deployment Manual page 12

802.1q Virtual LAN support is provided to work in conjunction with the Switch/Router attached to
the 1400 series wireless bridge. Both the wired Ethernet and wireless Radio interface supports
VLAN Trunking. Native Ethernet and 802.1q tagging is supported on both the Ethernet and Radio
interfaces.
ISL tagging, VTP and DTP are not supported in BR1400. The BR1400 treats VTP message like
any other multicast message and Transparently Bridges it across.
Thus, the Bridge participates in the 802.1d (spanning-tree) process of bridging two networks
together. You extend VLANs into a wireless LAN by adding IEEE 802.11Q tag awareness to the
bridge. VLAN 802.1Q trunking is supported between root and non-root bridges through the
bridges' primary SSID.
The basic wireless components of a VLAN consist of two or more bridges communicating using
wireless technology. The bridge is physically connected through a trunk port to the network VLAN
switch on which the VLAN is configured. The physical connection to the VLAN switch is through
the bridge's Ethernet port.

In fundamental terms, the key to configuring a bridge to connect to a specific VLAN is by
configuring its SSID to recognize that VLAN. Since VLANs are identified by a VLAN ID, it
follows that if the SSID on a bridge is configured to recognize a specific VLAN ID, a connection to
the VLAN is established.
The bridge supports only one infrastructure SSID. You should assign that SSID to the native
VLAN. For more information, please consult the VLAN deployment Guide at this URL:
