Multiple-Controller Deployments

Each controller can support lightweight access points across multiple floors and buildings simultaneously. However, full functionality of the Cisco Wireless LAN Solution is realized when it includes multiple controllers. A multiple-controller system has the following additional features:

•Autodetecting and autoconfiguring RF parameters as the controllers are added to the network.

•Same-Subnet (Layer 2) Roaming and Inter-Subnet (Layer 3) Roaming.

•Automatic access point failover to any redundant controller with a reduced access point load (refer to the “Cisco Wireless LAN Controller Failover Protection” section on page 1-20).

The following figure shows a typical multiple-controller deployment. The figure also shows an optional dedicated Management Network and the three physical connection types between the network and the controllers.
