Configuring WDS, Fast Secure Roaming, Radio
Management, and Wireless Intrusion Detection
Services
This chapter describes how to configure your access points for wireless domain
services (WDS), fast, secure roaming of client devices, radio management, and
wireless intrusion detection services (WIDS).
Understanding WDS
When you configure Wireless Domain Services on your network, access points
on your wireless LAN use the WDS device (either an access point, an Integrated
Services Router, or a switch configured as the WDS device) to provide fast,
secure roaming for client devices and to participate in radio management.
If you use a switch as the WDS device, the switch must be equipped with a
Wireless LAN Services Module (WLSM). An access point configured as the
WDS device supports up to 60 participating access points, an Integrated Services
Router (ISR) configured as the WDS devices supports up to 100 participating
access points, and a WLSM-equipped switch supports up to 600 participating
access points and up to 240 mobility groups.
Fast, secure roaming provides rapid reauthentication when a client device roams
from one access point to another, preventing delays in voice and other time-
sensitive applications.
