Cisco AIR-CT5520-K9 Wireless LAN Controller

The Cisco 5520 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 FlexConnectâ„¢ 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 and Cisco Catalyst® access points, the Cisco Prime®
Infrastructure, and the Cisco Mobility Services Engine, and is interoperable with
other Cisco controllers.

The Cisco Digital Network Architecture (Cisco DNA) is an open and extensible,
software-driven architecture that accelerates and simplifies your enterprise
network operations. The programmable architecture frees your IT staff from time-
consuming, repetitive network configuration tasks so they can focus instead on
innovation that positively transforms your business. SD-Access, as part of Cisco
DNA, enables policy-based automation from edge to cloud with foundational
capabilities. Cisco DNA Assurance, also part of Cisco DNA, provides a single
source to monitor, modify, and manage your network and application data.
