Overview of the Cisco 8540 Wireless Controller

The Cisco 8540 Wireless Controller provides centralized control, management, and troubleshooting for
high-scale deployments in service provider and large campus deployments. It offers flexibility to support
multiple deployment modes in the same controller: for example, centralized mode for campus, Cisco
FlexConnect mode for lean branches managed over the WAN, and mesh (bridge) mode for deployments
where full Ethernet cabling is unavailable. As a component of the Cisco Unified Wireless Network, this
controller provides real-time communications between Cisco Aironet access points, the Cisco Prime
Infrastructure, and the Cisco Mobility Services Engine, and is inter-operable with other Cisco
controllers.
