Enterprise Wireless Network Management

The Cisco C9800-L-C-K9 is a fixed wireless LAN controller from the Cisco Catalyst 9800 Series, designed to provide centralized control and management for enterprise wireless networks. The C9800-L platform combines Cisco IOS XE with enterprise-grade wireless management, security and automation capabilities in a compact 1RU appliance.

The C9800-L-C-K9 is the copper-uplink variant of the Catalyst 9800-L and provides four 2.5/1-Gigabit ports plus two 10/5/2.5/1-Gigabit ports. This gives organizations flexible high-speed Ethernet connectivity for management, network integration and wireless infrastructure deployment.

Key Features

High-Performance Wireless Infrastructure

The Catalyst 9800-L provides centralized management of Cisco wireless access points and wireless clients. It is designed to simplify deployment and ongoing operation through centralized configuration, monitoring, policy enforcement and security controls.

The platform is suitable for organizations that require a dedicated wireless controller without deploying a larger chassis-based Catalyst 9800 controller. Its compact form factor makes it suitable for branch offices, midsize enterprise networks, education, healthcare, hospitality and commercial environments.\

Copper Uplink Configuration

The C9800-L-C-K9 differentiates itself from the C9800-L-F-K9 through its copper Ethernet interface configuration. Cisco documentation lists the C9800-L-C-K9 with four 2.5/1-Gigabit ports and two 10/5/2.5/1-Gigabit ports.

Wireless Capacity

The standard Catalyst 9800-L platform supports up to 250 access points and 5,000 clients. An optional Cisco Performance License increases the supported capacity to 500 access points and 10,000 clients.

Enterprise Wireless Management

Cisco Catalyst 9800 controllers are built around Cisco IOS XE and provide centralized wireless network management. Administrators can configure access points, wireless policies, client access, security parameters and operational settings from the controller platform.

The controller supports management through web-based HTTP/HTTPS interfaces, command-line access including SSH, and serial connectivity. Cisco documentation also identifies NETCONF/YANG-based management capabilities for network automation and configuration.

Security and Network Control

The Catalyst 9800 platform provides centralized policy and security functions for enterprise wireless networks. It is designed to help organizations maintain consistent wireless configurations and security policies across managed access points and connected clients.

• Centralized wireless policy management
• Enterprise access-point management
• Wireless client management
• Secure management through SSH and HTTPS
• Network automation through supported NETCONF/YANG capabilities
• Centralized configuration and monitoring

Hardware and Physical Design

The Cisco Catalyst 9800-L is designed as a compact 1RU appliance, making it suitable for standard network racks and space-constrained enterprise deployments. The controller measures approximately 21.59 × 22.86 × 4.394 cm and weighs approximately 2 kg.

Power and Environmental Specifications

The controller uses the Cisco C9800-AC-110W power adapter and supports an AC input range of 100–240 VAC at 50–60 Hz. Cisco documentation specifies an operating temperature range of 0°C to 40°C.

Ideal Applications

Why Choose Cisco C9800-L-C-K9?

The Cisco C9800-L-C-K9 provides a compact and scalable platform for centralized enterprise wireless management. Its copper Multigigabit Ethernet interfaces, 1RU form factor, Cisco IOS XE software and support for up to 250 access points and 5,000 clients make it suitable for small and midsize wireless deployments.

Organizations requiring additional wireless capacity can use the optional Performance License to increase supported access points to 500 and clients to 10,000, while also increasing non-IMIX throughput capability to 10 Gbps.
