The Cisco

 Structured Wireless-Aware Network (Cisco SWAN) framework now includes the Cisco 

Catalyst 6500 Series Wireless LAN Services Module (WLSM). This document focuses on the WLSM 
and its integration into the Cisco SWAN framework. The WLSM offers these important benefits to the 
Catalyst 6500 series switches:

Very fast Layer 2 and Layer 3 roaming (less than 50 ms) for mobile users registered with the WLSM. 
This is especially important for Voice over IP (VoIP) support.

Increased scalability supporting up to 300 access points and up to 6000 mobile users. 

Simplified wired and wireless network management provided by a single entry point into the wired 
network for both wireless LAN control and user data.

A single quality of service (QoS) and security policy for all wireless users in a subnet. This is 
provided by a centralized entry point to the network using fast secure roaming tunnels (FSRTs) via 
a multipoint generic routing encapsulation (mGRE) tunnel on the Cisco Catalyst 6500 Series 
Supervisor Engine. 

Support for multiple service set identifiers (SSIDs) and VLANs on the access point, enabling 
wireless data traffic to be segregated into different roaming subnets or mobility groups.

Failover to a secondary WLSM using the Hot Standby Router Protocol (HSRP).

A centralized point for troubleshooting and debugging.

Support for advanced Catalyst 6500 switch features, including the Catalyst 6500 series service 
modules.
