Figure 5. Illustration of Large Branch Deployment Use Case
Main Campus Environment
This is typically a large environment with multiple buildings in one campus location. Scalability and the ability to
deploy timely services based on business needs become top priorities. Converged access for a main campus
environment can be implemented by multiple stacks of Cisco Catalyst 3850 switches to support wired and wireless
networking needs with separate 5760/5508/WiSM2 as dedicated WLCs. Each Cisco Catalyst 3850 stack serves as
a wireless mobility agent with multiple groups of access points. Notice that converged access can coexist with
other wireless deployment modes such as centralized, where existing wired and wireless infrastructure
components continue to use CAPWAP tunnels for wireless data traffic. With dedicated WLCs (5760/WiSM2/5508)
as mobility controllers, Cisco Unified Access supports the largest Layer 3 roaming domains, with up to 72,000
access points and up to 864,000 wireless endpoints.
Features: Scalable design; high performance; extensive mobility and roaming support; advanced QoS;
NetFlow; and other services for wireless and wired traffic, BYOD, and network intelligence.
Benefits: Highest scalability for large deployments (more than 250 access points), business agility with fast
service rollouts, simplified mobility deployment, and support for very large Layer 3 roaming domains.
