Configuring the Role in Radio Network
Note In point-to-multipoint bridging, WGB is not recommended with the root bridge. WGB should be
associated to the root AP in point-to-multipoint bridging setup.
Configuring Dual-Radio Fallback
The dual-radio fallback features allows you to configure access points so that if the non-root bridge link
connecting the access point to the network infrastructure goes down, the root access point link through
which a client connects to the access point shut down. Shutting down the root access point link causes
the client to roam to another access point. Without this feature, the client remains connected to the access
point, but will not be able to send or receive data from the network.
Figure6-1 Dual-Radio Fallback
