The documentation set for this product strives to use bias-free language. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product. Learn more about how Cisco is using Inclusive Language.
Your software release may not support all of the features documented in this module. For the latest feature information and caveats, see the release notes for your platform and software release.

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 device is aware of the clients that are associated with the access point. When non-Cisco WGBs are used, the device has no information about the IP address of the clients on the wired segment behind the WGB. Without this information, the device 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.

This example shows how to configure a WGB access point using static WEP with a 40-bit WEP key:
Device# configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
Device(config)# dot11 ssid WGB_with_static_WEP
Device(config-ssid)# authentication open
Device(config-ssid)# guest-mode
Device(config-ssid)# exit
Device(config)# interface dot11Radio 0
Device(config)# station-role workgroup-bridge
Device(config-if)# encry mode wep 40
Device(config-if)# encry key 1 size 40 0 1234567890
Device(config-if)# ssid WGB_with_static_WEP
Device(config-if)# end
Verify that the WGB is associated to an access point by entering this command on the WGB:
show dot11 association
Information similar to the following appears:
Device# show dot11 associations
