Information About Cisco Workgroup Bridges and non-Cisco
Workgroup bridges
A WGB is a mode that can be configured on an autonomous Cisco IOS access point to provide wireless
connectivity to a lightweight access point on behalf of clients that are connected by Ethernet to the WGB
access point. A WGB connects a wired network over a single wireless segment by learning the MAC addresses
of its wired clients on the Ethernet interface and reporting them to the lightweight access point using Internet
Access Point Protocol (IAPP) messaging. The WGB provides wireless access connectivity to wired clients
by establishing a single wireless connection to the lightweight access point.
When a Cisco WGB is used, the WGB informs the access points of all the clients that it is associated with.
The switch is aware of the clients that are associated with the access point. When non-Cisco WGBs are used,
the switch has no information about the IP address of the clients on the wired segment behind the WGB.
Without this information, the switch drops the following types of messages:
• ARP REQ from the distribution system for the WGB client.
• ARP RPLY from the WGB client.
• DHCP REQ from the WGB client.
• DHCP RPLY for the WGB client.
