Catalyst 9400 Series Supervisor Engine 1
Product Description
The Cisco C9400-SUP-1 is a modular supervisor engine designed for Cisco Catalyst 9400 Series switches, providing centralized control, system intelligence, and high-performance switching capabilities for enterprise campus networks.
Acting as the brain of the Catalyst 9400 chassis, the supervisor engine manages forwarding, routing, security, and system services while enabling advanced features through Cisco IOS-XE software. It supports scalable throughput, hardware-based forwarding, and high-availability options to ensure reliable network performance in mission-critical environments.
The module supports redundant supervisor configurations for nonstop forwarding and stateful switchover, helping enterprises maintain uptime while scaling campus or distribution-layer deployments.
