Bridges
The 1140, 1200, 1240, and 1250 series access points and the 1300 access point/bridge can be configured
as root or non-root bridges. In this role, an access point establishes a wireless link with a non-root bridge.
Traffic is passed over the link to the wired LAN. Access points in root and non-root bridge roles can be
configured to accept associations from clients. Figure1-3 shows an access point configured as a root
bridge with clients. Figure 1-4 shows two access points configured as a root and non-root bridge, both
accepting client associations. Consult the “Configuring the Role in Radio Network” section on page6-2
for instructions on setting up an access point as a bridge.
When wireless bridges are used in a point-to-multipoint configuration the throughput is reduced
depending on the number of non-root bridges that associate with the root bridge. The maximum
throughput is about 25 Mbps in a point to point link. The addition of three bridges to form a
point-to-multipoint network reduces the throughput to about 12.5 Mbps.
