产品详情
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.
Product Overview
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 , this controller provides real-time communications between , the , and the , and is interoperable with other Cisco controllers.

Features and Benefits
The Cisco 8540 Wireless Controller, optimized for 802.11ac Wave2 performance, high scale, and enhanced system uptime, supports:
● 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 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 data offload.
● Network-based mobility management with Proxy *6 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

Licensing
The Cisco 8540 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 6000 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 8540 Wireless Controller also provides an option to enable licensing using , 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.
