About the Cisco C9800-L-C-K9 Wireless Controller (C9800-L-C-K9)
The Cisco C9800-L-C-K9 Wireless Controller delivers enterprise-grade QoS, traffic shaping, and intelligent app-aware routing capabilities essential for high-density wireless deployments. As a 1RU fixed appliance within the Cisco Catalyst 9800 Series Wireless Controllers family, this platform manages up to 2,000 access points and 32,000 wireless clients simultaneously, delivering 10 Gbps system throughput. Connectivity is provided through 2 x 10G SFP+ fiber uplink ports for WAN redundancy, 4 x 1G RJ-45 copper Gigabit Ethernet ports for LAN services, plus a dedicated out-of-band management port and single RJ-45 console port. The controller runs Cisco IOS XE and supports stateful switchover (SSO) active/standby high availability with in-service software upgrades, ensuring zero-downtime operations in mission-critical environments.
Network engineers and IT procurement teams deploying enterprise campuses, healthcare facilities, and large distributed organizations choose the C9800-L-C-K9 for its comprehensive security and intelligence capabilities. The platform integrates MACsec encryption, encrypted traffic analytics (ETA), Cisco TrustSec, rogue access point detection, and wireless intrusion prevention system (WIPS) integration to protect against evolving wireless threats. Programmability via NETCONF, RESTCONF, and YANG data models with streaming telemetry enables deep automation and real-time visibility. Support for Cisco DNA Essentials, Advantage, and Premier subscription tiers, combined with SD-Access fabric WLC functionality featuring VXLAN and LISP integration, allows seamless extension into software-defined network architectures and zero-trust security models.
The C9800-L-C-K9 (manufacturer part number C9800-L-C-K9) is engineered for organizations requiring carrier-class reliability and scalability in wireless infrastructure. Whether managing 802.11a/b/g/n/ac/ax (Wi-Fi 6) environments or modernizing legacy deployments, this Cisco controller provides the density, performance, and policy enforcement that growing enterprises demand.
