Configuring Workgroup Bridges
A workgroup bridge (WGB) is used to connect wired networks over a single wireless segment. It does
this by informing the mesh access point of all the clients that the WGB has on its wired segment via IAPP
messages. In addition to the IAPP control messages, the data packets for WGB clients contains an extra
MAC address in the 802.11 header (4 MAC header, versus the normal 3 MAC data headers). The extra
MAC in the header is the address of the workgroup bridge itself. This extra MAC address is used to route
the packet to and from the clients.

WGB association is supported on both the 2.4-GHz (802.11b/g) and 5-GHz (802.11a) radios on the
AP1522, and the 2.4-GHz (802.11b) and 4.9-GHz (public safety) radios on the AP1524PS; however,
WGB client mode cannot be configured on the AP1522 or AP1524.

Supported platforms are autonomous WGBs AP1130, AP1240, AP1310, and the Cisco 3200 Mobile
Router (hereafter referred to as Cisco 3200) which configured as WGB can associate with a mesh access
point.
