Table 2-1 Cisco 5760 WLC Features
Feature	Benefits
Scalability	Supports up to 1000 APs and 12,000 wireless clients for business- critical wireless services. Unparalleled scalable wireless solution, which comprises multiple controllers, can support up to 72,000 APs and 864,000 wireless clients.
High Performance	Optimized for 802.11ac standard. Six 10G Cisco SFP+ (Small Form-Factor Pluggable) uplinks. Hardware assisted processing to provide up to 60 Gbps throughput with services such as a downloadable access control list (ACL), granular quality of service (QoS) queues, fairness algorithm, NetFlow v9 processing, and so on.
High Resiliency	Converged Access deployment mode provides hierarchical network design that constraints failure to smaller domains. Thereby it provides higher resiliency. Wireless clients recover quickly from switch failures within the Catalyst 3850 and the 5760 Controller stack automatically through stateful switchover (AP SSO). CT5760 in centralized deployment mode (also known as local mode) supports 1+1, N+1 resiliency, and AP SSO. Multiple link aggregation (LAG) support to protect against link failures, while optimal network connectivity is maintained.
Cisco IOS® Software-based Controller	Proven and security-hardened Cisco IOS® operating system. Well-known Cisco IOS® software CLI allows customers to leverage current management tools for operations. Cisco’s rich NetFlow eco-system enables customers to report on, monitor, analyze traffic on, and troubleshoot the wireless network.
ClientLink 2.0	Cisco ClientLink 2.0 technology improves downlink performance to all mobile devices including one, two, and three-spatial-stream devices on 802.11n and improves battery life on mobile devices such as smart phones and tablets.
CleanAir	Cisco CleanAir™ technology provides proactive, high-speed spectrum intelligence to combat performance problems due to wireless interference.
Radio Frequency (RF) Management	Provides both real-time and historical information about RF interference that impacts network performance across controllers via system-wide Cisco CleanAir™ technology integration.
Comprehensive End-to-End Security	Offers CAPWAP compliant Datagram Transport layer Security (DTLS) encryption to ensure encryption between access points and controllers or between controllers.
High Performance Video	Optimized video delivery via single stream for both wired and wireless clients. Supports Cisco VideoStream technology to optimize the delivery of business-critical multicast video applications across the WLAN.
End-to-end Voice	Supports Unified Communications for improved collaboration through messages, presence, and conferences. Supports all Cisco Unified Communications Wireless IP Phones for cost-effective, real-time voice services.
Advanced QoS	Consistent configuration CLI for both wired and wireless QoS through Modular QoS CLI. Granular QoS policies per access point (AP), service set identifier (SSID), radio, and client. Fair bandwidth allocation across wireless clients on an AP. Leverages Cisco’s proven Cisco IOS® software and ASIC technology to provide line-rate performance.
Advanced ACL	Simplifies and centralizes security policies through downloadable ACLs. ACLs are processed in hardware to provide line-rate performance.
Flexible Netflow v9	Network-wide visibility with Flexible Netflow for wireless clients.
Environmentally Responsible	Organizations may choose to turn off AP radios to reduce power consumption during off peak hours. Integrated WLC avoids the deployment of an additional device in the network.
Mobility and Security	Secure, reliable wireless connectivity and consistent end-user experience. Increased network availability through proactive blocking of known threats.
IPv6	Supports IPv6 addressing on interfaces with appropriate show commands for monitoring and troubleshooting. IPv6 ACLs are processed in hardware to provide line-rate performance.

Features

The 5760 Wireless Controller can operate in both converged access mode and centralized mode. Converged access mode provides a hierarchical network design that distributes the wireless data plane at the access layer on Cisco Catalyst^® switches for maximum performance and scale. Converged access mode provides maximum resiliency by constraining outages to smaller failure domains. Additionally, converged access mode delivers high availability with access point stateful failover (access point SSO), making sure SSIDs are highly available and have minimal effect on wireless clients. (See Tables 1 and 2)
