Optimized for 802.11ac Wave 2 performance, the intent-driven Cisco DNA ready Cisco® 5520 Wireless Controller is a highly scalable, service-rich, resilient, and flexible platform that enables next-generation wireless networks for medium-sized to large enterprise campus and branch deployments.

Product overview

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 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 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.

Features and benefits

The Cisco 5520 Wireless Controller, optimized for 802.11ac Wave 2 performance, high scale, and enhanced system uptime, supports:

     Intent-driven programmability and streaming telemetry.

     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 or a third-party NetFlow collector.

     Embedded wireless Bring-Your-Own-Device (BYOD) policy classification engine that allows classification of client devices and application of user group 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.

     Simplified GUI wizard for quick setup and intuitive dashboards for monitoring and troubleshooting.

     Cisco DNA and SD-Access Wireless, as well as Cisco DNA Assurance.

Cisco DNA SD-Access Wireless

SD-Access Wireless is Cisco’s next-generation architecture for enterprise networks. It is the industry’s first policy-based automation from the edge to the cloud. It enables network access in minutes for any user or device to any application without compromising on security. 

SD-Access Wireless enables policy-based automation for wired and wireless, automated provisioning of wired and wireless networks, group-based policy for users and connected devices, and a distributed wireless data plane for campus deployments. In addition, all clients roams are treated as Layer 2 roams across the network for distributed traffic.

Cisco DNA Analytics and Assurance

Cisco DNA Analytics and Assurance offers comprehensive network visibility. It collects data from users, devices, and applications to proactively identify problems. Network analytics and automation help IT quickly resolve issues, so you can increase availability and deliver a better user experience.

Environmentally responsible

  Organizations may choose to turn off access point radios to reduce power consumption during off-peak hours

Perpetual licensing

The Cisco 5520 Wireless Controller provides right-to-use (with End User License Agreement [EULA] acceptance) license enablement for faster time to deployment, with flexibility to add additional access points (up to 1500 access points) as business needs grow.

   Additional access point capacity licenses can be added over time.

   Right-to-use licensing (with EULA acceptance) for faster and easier license enablement.

Starting with the 8.2 release, the Cisco 5520 Wireless Controller also provides an option to enable licensing using Cisco Smart Software Licensing, designed for easy monitoring and consumption of licenses.

   Manage license deployments with real-time visibility to ownership and consumption.

   Pools license entitlements in a single account. Licenses can be moved freely through the network–wherever they are needed.

Cisco does not allow porting of non-Cisco ONE perpetual AP licenses (like former Base capacity or capacity upgrade “Adder” licenses) from any older Cisco Wireless Controllers (eg. Cisco 2504, 4400, 5508, 7510, 8510 Wireless controllers) to Cisco 3504, 5520, and 8540 Wireless controller.

Cisco does allow porting of perpetual AP licenses between Cisco 3504, 5520 and 8540 Wireless Controllers.

Term-based licensing

With the Cisco DNA architecture, we are also introducing term-based software packages: Cisco DNA Essentials, Cisco DNA Advantage, and Cisco DNA Premier. In addition to on-box capabilities, the Cisco DNA packages unlock additional functionality in Cisco DNA Center, enabling controller-based software-defined automation in your network.

License consumption is further simplified with the following three package combinations. Cisco Embedded Support is included in all the three packages.

Essentials: Term-based (3, 5, or 7 years per access point) Cisco DNA Essentials package, term-based access point license, and term-based Cisco Prime Lifecycle and Assurance infrastructure licenses.

Advantage: Term-based (3, 5, or 7 years per access point) Cisco DNA Advantage package. It also includes everything in the Cisco DNA Essentials package.

Cisco DNA Premier: Term-based (3, 5, or 7 years per access point) Cisco DNA Advantage package (includes Cisco DNA Essentials package), Cisco Identity Services Engine (ISE) Base, ISE Plus and Cisco Connected Mobile Experiences (CMX) Base.

You can continue to deploy your network using perpetual licensing or the new term-based packages. The term-based licensing provides you with the additional benefit of using the same Cisco DNA license on any Cisco WLAN controllers and with any Aironet access point.
