This product bulletin describes new features for Cisco® WLSM Software Release Image Version 2.1.1, a deployment release supporting the Cisco Catalyst® 6500 Series Wireless LAN Services Module (WLSM). Note that the Cisco Catalyst 6500 Series WLSM Version 2.1.1 software release requires a corresponding software upgrade on the Supervisor Engine 720 module* and Cisco Aironet® access points** to enable all new features.
PRODUCT OVERVIEW
The Cisco Catalyst 6500 Series Wireless LAN Services Module (WLSM) provides fast secure campuswide wireless Layer 3 roaming and can greatly simplify wireless deployments and ongoing network operations. The Cisco Catalyst 6500 Series WLSM supports Cisco Aironet® autonomous access points and operates as a Wireless Domain Services (WDS) device. Cisco WLSM Software Release Image Version 2.1.1 supports several new features as well as all of the features in Image Version 1.4 and prior releases (Table 1).

Feature
Description
Increased Access Point Scalability
Memory and software improvements increase scalability of Cisco Catalyst 6500 Series WLSM from 300 to 600 access points per WLSM.
Active and Standby WLSMs Per Chassis
Active and standby WLSMs in a common Cisco Catalyst 6500 Series chassis provide the ability for administrators to deploy a second WLSM in a given chassis for failover support. One WSLM serves in an active role, the other WLSM serves in a standby role at any given time.
Resilient Tunnel Recovery for Wireless**
Automatic recovery of mobility tunnels after WLSM failure with zero client interruption.
RADIUS-Based Mobility Group Assignment**
This feature provides the ability to assign wireless users to different mobility groups based on user credentials stored in the RADIUS server.
IGMP Snooping-Based Multicast for Wireless**
This feature provides the ability to deliver multicast traffic to wireless clients across the Native VLAN of an access point without requiring the need for trunking or multiple multicast enabled networks on the first hop layer 3 router. With this feature, the access point is able to deliver multicast to wireless clients with dynamically assigned mobility groups.
Support for 240 Mobility Groups
This feature increases the number of mobility groups that may be assigned per WLSM. Mobility groups may be dynamically assigned based upon user authentication or posture validation. With 240 mobility groups supported per WLSM, each mobility domain may be smaller, thus reducing the subnet size required for each mobility group.
Enhanced Cisco Catalyst WLSM MIB Support
MIB support (CISCO-WDS-INFO-MIB) introduces the capability of querying the Cisco Catalyst 6500 Series WLSM for client, access point, and WLSM configuration and statistics. This information may be used to query the WLSM for client association, roaming, and performance data via the CiscoWorks Wireless LAN Solution Engine (WLSE) or custom Simple Network Management Protocol (SNMP) applications.
* Supervisor Engine 720 must be running software release 12.2(18)SXF2 or later.
** Cisco Aironet access points must be running Cisco IOS Software release 12.3(8)JA or later.
