Cisco-Catalyst C9400-SUP-1
The Cisco Catalyst C9400-SUP-1 is a supervisor engine for the Cisco Catalyst 9400 Series modular enterprise switches, designed to provide centralized control, high-performance Layer 2/Layer 3 switching, routing, security, redundancy, and network management for campus and enterprise networks.
Description
The Cisco Catalyst C9400-SUP-1 is a Supervisor Engine 1 designed for Cisco Catalyst 9400 Series chassis. As the central control and management component of a modular Catalyst 9400 system, it provides the processing, switching intelligence, routing, and management functions required to operate the chassis and its installed line cards.
The supervisor is designed for enterprise campus networks, distribution layers, and high-availability access deployments where organizations require a modular switching platform capable of scaling to a large number of Ethernet interfaces.
The C9400-SUP-1 operates with Cisco IOS XE, providing enterprise-grade Layer 2 and Layer 3 capabilities. It supports technologies such as VLANs, Layer 3 routing, IPv4/IPv6, OSPF, EIGRP, BGP, VRF, multicast, QoS, and advanced network security.
The supervisor also provides centralized management and control of the Catalyst 9400 chassis, including installed line cards, power systems, and network interfaces. It supports Cisco’s software-defined networking and automation architecture, including integration with Cisco DNA Center.
For high-availability deployments, the Catalyst 9400 platform supports redundant supervisor configurations when compatible supervisor engines are installed. This helps minimize downtime and provides improved resilience for critical enterprise networks.
The C9400-SUP-1 is designed to work as part of the Catalyst 9400 modular chassis architecture and should not be treated as a standalone Ethernet switch. Its capabilities depend on the chassis, line cards, power supplies, software release, and licensing configuration.
