Chapter 19 Configuring Repeater and Standby Access Points and Workgroup Bridge Mode
Using Workgroup Bridges in a Lightweight Environment
• When you delete a workgroup bridge record from the controller, all of the workgroup bridge wired
clients’ records are also deleted.
• Wired clients connected to a workgroup bridge inherit the workgroup bridge’s QoS and AAA
override attributes.
• These features are not supported for wired clients connected to a workgroup bridge:
–
MAC filtering
–
Link tests
–
Idle timeout
• You do not need to configure anything on the controller to enable the workgroup bridge to
communicate with the lightweight access point. However, to ensure proper communication, you
should create a WLAN on the controller that matches the SSID and security method that was
configured on the workgroup bridge.
Sample Workgroup Bridge Configuration
Here is a sample configuration of a workgroup bridge access point using static WEP with a 40-bit WEP
key:
ap#confure terminal
Enter configuration commands, one per line. End with CNTL/Z.
ap(config)#dot11 ssid WGB_with_static_WEP
ap(config-ssid)#authentication open
ap(config-ssid)#guest-mode
ap(config-ssid)#exit
ap(config)#interface dot11Radio 0
ap(config)#station-role workgroup-bridge
ap(config-if)#encry mode wep 40
ap(config-if)#encry key 1 size 40 0 1234567890
ap(config-if)#WGB_with_static_WEP
ap(config-if)#end
To verify that the workgroup bridge is associated to an access point, enter this command on the
workgroup bridge:
show dot11 association
If a wired client does not send traffic for an extended period of time, the workgroup bridge removes the
client from its bridge table, even if traffic is continuously being sent to the wired client. As a result, the
traffic flow to the wired client fails. To avoid the traffic loss, prevent the wired client from being removed
from the bridge table by configuring the aging-out timer on the workgroup bridge to a large value using
the following IOS commands on the workgroup bridge:
configure terminal
bridge bridge-group-number aging-time seconds
exit
end
where bridge-group-number is a value between 1 and 255, and seconds is a value between 10 and
1,000,000 seconds. We recommend configuring the seconds parameter to a value greater than the wired
client’s idle period.
