field.
Check the Ethernet Bridging check box to enable Ethernet bridging or uncheck it to disable this feature.
Step 6
Select the appropriate backhaul rate for the 802.11a backhaul interface from the Bridge Data Rate

drop-down menu. Cisco recommends setting the backhaul rate to auto.
When the bridge data rate is set to auto, the mesh backhaul chooses the highest rate possible given its
link quality and the ability to sustain of that rate.
Step 8 Click Apply to commit your changes. An Ethernet Bridging section appears at the bottom of the window
listing each of the Ethernet ports of the mesh access point.
Configuring Bridge Group Names
Bridge group names (BGN) controls the association of mesh access points. BGNs can logically group
radios to avoid two networks on the same channel from communicating with each other. The setting is
also useful if you have more than one RAP in your network in the same sector (area). BGN is a string of
10 characters maximum.
A BGN of NULL VALUE is assigned by default by manufacturing. Although not visible to you, it allows
a mesh access point to join the network prior to your assignment of your network-specific BGN.
If you have two RAPs in your network in the same sector (for more capacity), Cisco recommends that
you configure the two RAPs with the same BGN, but on different channels.
Using the CLI to Configure BGN
To configure a BGN, follow these steps:
Using the CLI, enter the following command:
Step 1
T
The mesh access point reboots after BGN configuration.
Note
Be careful when configuring BGN on a live network. Always start BGN assignment from the
Caution
farthest-most node (last node, bottom of mesh tree) and move up towards the RAP. This ensures that no
mesh access points are dropped due to mixed BGNs (old and new BGNs) within the same network.
To verify the BGN, enter the following command:
