About the Cisco WLC 2504 AIR-CT2504-K9 Cisco wireless LAN controller
The Cisco WLC 2504 AIR-CT2504-K9 is an on-box controller designed for centralised wireless management without cloud dependency, operating under Cisco AireOS and supporting base licensing for 5 access points, expandable to 75 APs with full licensing. This mid-range wireless LAN controller delivers enterprise-grade network control through CLI, web GUI, and SNMP interfaces, with optional integration into Cisco Prime Infrastructure and Cisco DNA Center for enhanced visibility.
Network engineers and IT procurement teams deploying mid-sized wireless campuses choose the WLC 2504 for its proven ability to manage up to 500 concurrent client sessions across multiple IEEE 802.11a, 802.11b, 802.11g, and 802.11n access points via CAPWAP protocol. The unit provides four 1000BASE-T Gigabit Ethernet LAN ports plus dedicated out-of-band 10/100BASE-T service and RJ-45 serial console connectivity, enabling resilient network segregation and emergency access. Built-in security encompasses WPA2 encryption, 802.1X and RADIUS authentication, rogue AP detection and containment, access control lists, and guest WLAN segmentation—critical features for organisations requiring strict compliance and threat mitigation. QoS capabilities including 802.11e, WMM, and application-level policies ensure prioritised traffic handling across the wireless domain.
Available in desktop or 1U rack-mountable form factors with an external AC power adapter, the WLC 2504 operates reliably across standard enterprise environments (0°C to 40°C), holds FCC, CE, and UL regulatory approval, and integrates seamlessly into existing Cisco infrastructure. Whether you require a dedicated on-premises controller for regulatory isolation or a straightforward, licence-based AP management platform, the Cisco AIR-CT2504-K9 offers proven scalability and control.
