Overview of Workgroup Bridge
A workgroup bridge (WGB) is a Cisco access point that can be configured in a mode that permits it to associate with a wireless infrastructure, providing network access on behalf of wired clients. It is also called as a wireless bridge.
Note |
This document only covers WGB mode on the Cheetah OS (COS) APs. |
A Cisco WGB provides information about its wired clients via Internet Access Point Protocol (IAPP) messaging. This enables the wireless infrastructure to know the MAC addresses of the WGB’s wired clients. Up to 20 wired clients are supported behind a Cisco WGB.
-
The following authentication modes are supported for use with a WGB:
Open, PSK, dot1X (including LEAP, PEAP, FAST, TLS)
-
Wired clients connected to the WGB are not authenticated for security. Instead, the WGB is authenticated against the access point to which it associates. Therefore, we recommend that you physically secure the wired side of the WGB.
-
Wired clients connected to a WGB inherit the WGB’s QoS and AAA override attributes.
-
To enable the WGB to communicate with the lightweight access point, create a WLAN and make sure that Aironet IE is enabled. To associate to a Cisco AP, make sure that Aironet IE is enabled on the controller.
