Configuring WDS, Fast Secure Roaming, Radio Management, and Wireless Intrusion Detection Services Chapter 13
Understanding Radio
Management Access points participating in radio management scan the radio environment and
send reports to the WDS device on such radio information as potential rogue
access points, associated clients, client signal strengths, and the radio signals from
other access points.
The WDS device forwards the aggregated radio data to the WLSE device on
your network. Access points participating in radio management also assist with
the self-healing wireless LAN, automatically adjusting settings to provide
coverage in case a nearby access point fails. See
Configuring Radio Management
on page 400 for more information on configuring radio management.

Understanding Layer 3
Mobility When you use a WLSM as the WDS device on your network, you can install
access points anywhere in a large Layer 3 network without configuring one
specific subnet or VLAN throughout the wired switch infrastructure. Client
devices use multipoint GRE (mGRE) tunnels to roam to access points that reside
on different Layer 3 subnets. The roaming clients stay connected to your network
without changing IP addresses.
For instructions on configuring WDS on a switch equipped with a Wireless
LAN Services Module (WLSM), see the
Cisco Catalyst 6500 Series Wireless
LAN Services Module (WLSM) Deployment Guide .
The Layer 3 mobility wireless LAN solution consists of these hardware and
software components:
• The Stratix 5100 WAP and these Cisco devices (1040, 1100, 1130, 1200,
1240, and 1260 series access points) participate WDS.
• Catalyst 6500 switch with Supervisor Module and WLSM configured as
the WDS device
• Client devices
TIP You must use a WLSM as your WDS device to properly configure Layer 3
mobility. Layer 3 mobility is not supported when you use an access point as
your WDS device.
