Cisco IOS Release 12.2(11)JA
This section lists new features in Cisco IOS Release 12.2(11)JA for the bridge.
•
Antenna alignment assistance
–
This feature provides a wireless bridge with an auto-configuration and installation mode for
out-of-box deployment of point-to-point links without requiring configuration through telnet,
file transfer protocol (FTP), or Simple Network Management Protocol (SNMP). This mode
drives LEDs and a received signal strength indicator (RSSI) port with a voltage output
proportional to the received signal strength for use during the installation and alignment
process. This allows a wireless bridge installation team without knowledge of Cisco IOS
software or data networking to install and verify the quality of the wireless link.

•
Wireless programmable clear channel assessment
–
With the programmable clear channel assessment feature, wireless bridges can be configured to
a particular background interference level found in a specific environment for reduced overhead
contention with other wireless systems.

•
Wireless root bridge
–
A wireless bridge connected to the main LAN network can be configured as a wireless root
bridge to provide support for point-to-point or point-to-multipoint bridging.

•
Wireless non-root bridge
–
A wireless bridge connected to a remote LAN network can be configured as a wireless non-root
bridge to allow operation as the remote node in a point-to-point or point-to-multipoint network.

•
Wireless packet concatenation
–
Wireless packet concatenation is the concatenation of smaller packets into larger ones to more
efficiently use the wireless medium and provide higher overall data throughputs on a wireless
bridge.

•
Wireless link distance adjustment
–
The wireless link distance adjustment parameter enables you to tune the carrier sense multiple
access with collision avoidance (CSMA/CA) parameters for a particular range to maximize the
performance of a wireless bridge.
