Application Security Appliance Service Module (Asa-Sm) - Cisco Catalyst 6500-E Series Manual

Figure 2. Campus Wireless Deployment Scenarios
In the hybrid deployment model, an organization will have a mix of Cisco Catalyst 3850 Series (shown as the two
switches on the left) in addition to Cisco Catalyst 4500-E (shown) or 3750-X Series in the access layer. This could
be in a network where there is a mix of highly mobile users, who will need some of the advanced capabilities of the
Cisco Catalyst 3850 Series, and back-office users, who will be more stationary and will not need those services. In
this case, the Cisco Catalyst 6500 Series with Supervisor Engine 2T and WiSM2 is used to terminate the sessions
of the back-office users, while the Cisco Catalyst 3850 Series will terminate the sessions for the mobile users. This
means that an organization that has already made an investment in WiSM2 can protect that investment while at
the same time enhancing its infrastructure with Cisco Catalyst 3850 technology.
In the traditional deployment, the organization has not yet deployed the Cisco Catalyst 3850 Series, or it might
have no plans to do so for whatever reason (budget, technology requirements, and so on). In this case, the Cisco
Catalyst 6500-E Series with Supervisor Engine 2T and WiSM2 is used to terminate all wireless sessions for the
organization, providing the most scalable and highly available wireless infrastructure to meet the organization's
BYOD, video, and collaboration needs.

Application Security Appliance Service Module (ASA-SM)

The Cisco Catalyst 6500-E Series ASA Services Module (ASA-SM) delivers advanced technology that
transparently integrates with the Cisco Catalyst 6500-E with Supervisor Engine 2T to provide sophisticated
security, virtualization, reliability, and performance. The ASA-SM supports up to 16 Gbps of multiprotocol
firewalling, up to 2 million access control entries(ACEs), and up to 250 virtual contexts, making it the perfect
firewall solution to support the scalability and network virtualization required in a unified campus architecture
supporting BYOD, video, and collaboration, as shown in Figure 3.
