WMIC Configurations
WMIC Work Group Bridge Configuration
WMICs can support the WGB client mode for 802.11 associated connections. This is the only operating
mode that supports the distance command. It is also the suggested mode to configure for the MAR in a
Cisco mesh environment because it overcomes limitations known to the UWGB client mode. For more
information on UWGB including its limitations, see

There are the following three install modes for WGB:
•
Automatic activates the bridge install and alignment mode, and specifies that the unit automatically
determines the network role. If the unit is able to associate to another Cisco root device within
60 seconds, the unit assumes a non-root bridge role. The device can be configured into root bridge
or non-root bridge modes to avoid the 60-second automatic detection phase.

60 seconds, the unit assumes a non-root bridge role. The device can be configured into root bridge
or non-root bridge modes to avoid the 60-second automatic detection phase.
•
Root specifies that the device is operating as a root bridge and connects directly to the main Ethernet
LAN network. In this mode, the unit accepts associations from other Cisco bridges and wireless
client devices.
LAN network. In this mode, the unit accepts associations from other Cisco bridges and wireless
client devices.
•
Non-root specifies that the device is connecting to a remote LAN network, and that it must associate
with a Cisco root device by using the wireless interface.
with a Cisco root device by using the wireless interface.
Follow these steps to configure the WMIC to determine is role automatically:
Step 1
Under the dot11 interface, enter the following command.
station-role {root [bridge | non-root workgroup-bridge install [automatic | root |
non-root]}
The station-role command specifies that the role of the WMIC is chosen based on the device to which
it is associated.
it is associated.
Step 2
Set the WMIC role.
•
station-role root bridge—Specifies that the 3200 MAR WMIC operates as the root bridge device.
This mode does not support wireless client associations.
This mode does not support wireless client associations.
•
station-role workgroup-bridge—Specifies that the 3200 MAR WMIC operates in workgroup
bridge mode. As a workgroup bridge, the device associates to an Aironet access point or bridge as
a client and provides a wireless LAN connection for devices connected to its Ethernet port.

Step 3
Issue the mobile station command.
mobile station
Use this command to configure a non-root bridge or workgroup bridge as a mobile station. When this
feature is enabled, the bridge scans for a new parent association whenever it encounters a poor received
signal strength indicator (RSSI), excessive radio interference, or a high frame loss percentage. Using
