Services Integration; Wireless Services Module 2 (Wism2) - Cisco Catalyst 6500-E Series Manual

The Cisco Catalyst 6500-E with Supervisor Engine 2T is capable of supporting up to 4 terabits per second of data
forwarding in a virtual switching system (VSS) configuration while maintaining a level of availability that can deliver
99.999 percent uptime to make sure of operational continuity. The Supervisor Engine 2T supports advanced
features that allow an organization to build a highly scalable, secure, converged wired and wireless campus
network. This paper focuses on five primary areas in which a Cisco Catalyst 6500-E with Supervisor Engine 2T
delivers unmatched feature functionality to enable a unified access campus architecture:

Services Integration

●
Smart Operations
●
Security
●
Application Visibility and Control
●
Resiliency
●
Services Integration
With the innovative Cisco integrated service modules, network managers can deploy a broad range of LAN
interfaces, security services, and content and network analysis services within the same platform. The modules
are designed to take full advantage of the functionality and intelligence of the Cisco Catalyst 6500-E with
Supervisor Engine 2T.
The integrated service module architecture simplifies infrastructure complexity through system and services
integration, network virtualization, and simplified management and high availability, which all lead to a lower TCO.
The current portfolio of services modules supported by the Supervisor Engine 2T includes, but is not limited to, the
WiSM2, Network Analysis Module 3 (NAM-3), and Adaptive Security Appliance Service Module (ASA-SM). These
three represent the newest generation of service modules in their respective areas of wireless, application
visibility/control, and security and provide primary capabilities to support a unified access campus architecture.

Wireless Services Module 2 (WiSM2)

The Cisco Wireless Services Module 2 (WiSM2) Controller for Cisco Catalyst 6500-E Series Switches is a highly
scalable and flexible platform that enables systemwide services for mission-critical wireless networking in medium-
sized to large enterprises and campus environments. Designed for
scalability, the Cisco WiSM2 controller supports a higher density of clients and delivers more efficient roaming,
with at least nine times the throughput of existing 802.11a/g networks. The WiSM2 controller has the ability to
simultaneously manage up to 1000 access points, providing up to 20 Gbps of bandwidth and subsecond stateful
failover of all access points from primary to standby controller.
The proliferation of wireless devices in enterprise campus networks as a result of BYOD is promoting the need for
a converged wired and wireless infrastructure to provide ease of management as well as high availability to
support delay-sensitive applications such as voice and video. The introduction of the Cisco Catalyst 3850 switch is
a prime example of the convergence of wired and wireless, but there will be use cases where the Cisco Catalyst
3850 does not apply. Take, for example, the different options in Figure 2.
