How to install Cisco Catalyst 9800-L

• Plan your deployment by identifying coverage goals, AP density, and critical WLANs. Map coverage areas, select optimal mounting locations for the controller, and ensure your network switch fabric provides adequate uplink capacity for peak traffic.
• Power on and connect the Catalyst 9800-L to your management network and the APs it will control. Use a dedicated management VLAN and ensure proper physical security for the appliance in a data center, wiring closet, or protected rack.
• Access the controller’s management interface from a workstation on the same network. Use the initial credentials and follow the on‑screen setup wizard to configure basic network settings, admin accounts, and access restrictions.
• Apply initial software and license provisions. Keep the controller current with the latest IOS XE release to ensure compatibility with Wi‑Fi 6 features and security enhancements.
• Configure IP connectivity, DNS, NTP, and time zones to ensure accurate logs and synchronized monitoring across your WLAN environment.
• Define WLANs (SSIDs), security policies (encryption and authentication), and guest access rules. Map SSIDs to appropriate VLANs and apply appropriate QoS and firewall policies for different user groups.
• Enroll APs and associate them with the Catalyst 9800-L. Perform basic RF optimization, including channel assignment and power levels, then run a site survey to verify coverage and adjust as needed.
• Integrate with Cisco DNA Center or your preferred management platform to automate provisioning, apply templates, and monitor the health and performance of wireless clients in real time.
• Set up ongoing maintenance routines, including routine firmware updates, backup configurations, and proactive security monitoring to minimize downtime and protect against evolving threats.
