Background Information
WDS is a part of the Cisco Structured Wireless−Aware Network (SWAN). WDS is a collection of Cisco IOS
Software features that enhance Wireless LAN (WLAN) client mobility and simplify WLAN deployment and
management.
Software features that enhance Wireless LAN (WLAN) client mobility and simplify WLAN deployment and
management.
WDS is the base for many features such as Fast Secure Roaming, Layer 3 mobility, and radio management.

One of the main purposes of WDS is to cache the user credentials at the first authentication of the client by the
authentication server. On subsequent tries, WDS authenticates the client on the basis of the cached
information. In order to accomplish this:
authentication server. On subsequent tries, WDS authenticates the client on the basis of the cached
information. In order to accomplish this:
One of the APs must be configured as a WDS AP.
•
Other APs must be configured as infrastructure APs that communicate to the WDS AP.
•
WDS AP must establish a relationship with the authentication server by authenticating to it with a
WDS username and password.
WDS username and password.
•
This authentication server validates the credentials of the infrastructure APs and the clients when these
devices authenticate for the first time. The authentication server can either be an external RADIUS server or
the local RADIUS server on the WDS AP.

the local RADIUS server on the WDS AP.
The WDS and the infrastructure APs communicate over a multicast protocol called the Wireless LAN Context
Control Protocol (WLCCP). These multicast messages cannot be routed. Therefore, a WDS and associated
infrastructure APs must be in the same IP subnetwork and on the same LAN segment.

This document explains how to use the local RADIUS server feature on the WDS AP to perform the
validation of credentials.

In this section, you are presented with the information to configure the features described in this document.
In order to configure the AP to serve as a WDS AP with AAA server functionality, you must first enable the
local RADIUS server feature on the AP.
