Chapter 7 Controlling Lightweight Access Points
Cisco Workgroup Bridges
Follow these steps to perform the TFTP recovery procedure.
Step 1 Download the required recovery image from Cisco.com (c1100-rcvk9w8-mx, c1200-rcvk9w8-mx, or
c1310-rcvk9w8-mx) and install it in the root directory of your TFTP server.
Step 2 Connect the TFTP server to the same subnet as the target access point and power-cycle the access point.
The access point boots from the TFTP image and then joins the controller to download the oversized
access point image and complete the upgrade procedure.
Step 3 After the access point has been recovered, you may remove the TFTP server.
Cisco Workgroup Bridges
A workgroup bridge (WGB) is a mode that can be configured on an autonomous 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. The lightweight access point treats the WGB as a wireless client. See the
example in Figure 7-22.
Figure 7-22 WGB Example
Note If the lightweight access point fails, the WGB attempts to associate to another access point.
Figure 7-23 shows how a WGB is connected in a basic mesh network.
