2. Full Product Overview

Cisco AIR-CT5760-50-K9 is a mid-high capacity model of the discontinued Cisco 5700 Series wireless LAN controller, the first enterprise WLC platform built on native Cisco IOS-XE OS and powered by Unified Access Data Plane (UADP) programmable ASIC hardware acceleration. It is designed for large enterprise remote headquarters, multi-building school campuses, multi-cloud internet perimeters, high-density Software-Defined Data Center (SDDC) east-west workload segmentation, and premium mid-tier MSSP multi-tenant wireless security nodes that demand high 10G uplink bandwidth and expandable AP capacity beyond the entry AIR-CT5760-25-K9 variant.

As a core component of Cisco Next-Generation Converged Access Wireless Architecture, it terminates DTLS encrypted CAPWAP tunnels from all joined Aironet lightweight access points to deliver centralized RF management, enterprise wireless security policy enforcement, seamless Layer 2/3 client mobility, VoWLAN voice QoS, VideoStream multicast optimization, embedded wireless intrusion prevention (wIPS), and native application-aware SD-WAN routing. This unit ships with a permanent built-in license supporting up to 50 APs; incremental right-to-use AP adder licenses can expand capacity all the way up to the hardware maximum of 1000 APs without hardware replacement, supporting long-term wireless network expansion.

The 5760 platform delivers hardware-accelerated 60 Gbps non-blocking switching throughput via UADP ASIC, equipped with six SFP+ 10-Gigabit uplink slots supporting copper, short-range SR and long-range LR fiber transceivers for flexible uplink media selection. It features hot-swappable redundant cooling fans and optional dual redundant power supplies to eliminate single points of hardware failure for mission-critical campus wireless networks. Key resiliency feature: AP Stateful Switchover (AP SSO) HA fully synchronizes AP registration data and CAPWAP tunnels between redundant controllers; client session state synchronization is not supported on this platform. It supports exclusive Intel QuickAssist (QAT) crypto offload on certified Cisco UCS servers to drastically reduce CPU overhead for massive TLS 1.2/1.3 decryption and high-volume IPsec VPN processing.

The entire Cisco 5760 Series reached Cisco End-of-Sale (EoS) April 14, 2017 and End-of-Support (EoL) April 30, 2022; all available inventory consists of surplus, used, or certified refurbished hardware. Administrators can configure standalone instances via lightweight Firepower Device Manager (FDM) local HTTPS web GUI, IOS-XE CLI over SSH/Telnet, or serial console; centralized multi-controller fleet orchestration is available through Cisco Prime Infrastructure. It fully interoperates with all Aironet 802.11n / 802.11ac Wave 1/2 lightweight access points.

Key Upgrade vs AIR-CT5760-25-K9: Larger native 50 AP base license footprint, enhanced CPU/memory resource allocation for larger client session tables and heavier bulk TLS decryption workloads, higher maximum concurrent AnyConnect remote access VPN sessions, and support for linear throughput scaling via multi-node mobility clustering.
