The Cisco Catalyst 6500 Series Wireless LAN Services Module (WLSM), part of the Catalyst 6500 Series of multilayer switches and a key component of the Cisco Structured Wireless-Aware Network (SWAN) framework, is the industry's only enterprise-class wireless and wireline switching system, enabling secure, easily managed unified networking deployments for enterprises, midsize businesses, universities, and service providers by: Enabling the industry's fastest, secure campus-wide Layer 3 roaming system; Allowing customers to segment and individually authenticate, control access to, and manage disparate wireless user groups such as "guest" and "employee" by enabling wireless mobility groups; Extending the Catalyst 6500 Series' rich, intelligent network services, such as denial of service (Dos) prevention, access control lists (ACLs), firewall, network-based intrusion detection, and VPN services through the wired network to the wireless edge; Maximizing network uptime for wireless traffic with the industry's only Layer 3 Supervisor Non-Stop Forwarding/Stateful Switchover (NSF/SSO) system for wireless traffic; Simplifying management and deployment of wireless networks by providing "out-of-box" access point configuration and a single point of ingress for wireless traffic, with the ability to define wireline policies on a per wireless mobility group basis.To deploy wireless services within a campus environment, customers can simply configure the Catalyst 6500 Series WLSM to support up to 300 access points and 6000 users in any existing Catalyst 6500 Series switch that is equipped with a Supervisor Engine 720.
