Cisco 8540 Wireless Controller


Optimized for 802.11ac Wave2 performance, the Cisco® 8540 Wireless Controller is a highly scalable, service-rich, resilient, and flexible platform that enables next-generation wireless networks for medium-sized to large enterprise and campus deployments.

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 interoperable with other Cisco controllers.


  • Subsecond access point and client failover for uninterrupted application availability.
  • Extraordinary visibility into application traffic, using Cisco Application Visibility and Control (AVC), the technology that includes the Network Based Application Recognition 2 (NBAR2) engine, Cisco's Deep Packet Inspection (DPI) capability. This allows to mark, prioritize, and block to conserve network bandwidth and enhance security. Customers can optionally export the flows to Cisco Prime Infrastructure.
  • Embedded wireless bring-your-own-device (BYOD) policy classification engine that allows classification of client devices and application of user group based policies.
  • Deployment of guest access and Bonjour and Chromecast services in centralized deployments.
  • Software-defined segmentation with Cisco TrustSec® technology, reducing access control list (ACL) maintenance, complexity and overhead.
  • Integrated Cisco CleanAir® technology, providing the industry’s only self-healing and self-optimizing wireless network.
  • Wi-Fi Alliance Passpoint (Hotspot 2.0) for mobile data offload.
  • Network-based mobility management with Proxy Mobile IPv6 Mobility Access Gateway (MAG) and eGRE support for integration with cellular data networks
  • Simplified GUI wizard for quick setup and intuitive dashboards for monitoring and troubleshooting
