Catalyst 9400 Series Supervisor Engine 1XL
Product Description
The Cisco C9400-SUP-1XL is an enhanced supervisor engine for Cisco Catalyst 9400 Series switches, delivering higher scalability, larger forwarding tables, and improved performance compared to the standard SUP-1.
Designed for demanding enterprise campus and distribution networks, the SUP-1XL provides centralized switching intelligence, advanced routing capabilities, and secure network services through Cisco IOS-XE software. Its expanded hardware resources support larger deployments, more endpoints, and greater policy scale, making it ideal for growing campus infrastructures.
The supervisor supports redundant deployment for stateful switchover and nonstop forwarding, ensuring continuous network operation during upgrades or failures.
