Product Brief
The Cisco C9400-SUP-1XL is a high-performance supervisor engine designed for the Cisco Catalyst 9400 Series modular switches. It offers enhanced scalability, programmability, and resiliency, making it ideal for large-scale enterprise core and aggregation networks. With up to 960 Gbps system bandwidth, it is built to support next-generation networking demands including Cisco SD-Access, DNA Center, and full-stack security.
Product Details
The C9400-SUP-1XL delivers twice the bandwidth of the standard C9400-SUP-1, supporting up to 480 Gbps per slot. It comes with a powerful 8-core x86 CPU, enhanced memory, and full support for encrypted traffic analytics, NetFlow, and telemetry. With Cisco IOS XE software, this supervisor enables advanced automation, policy enforcement, and Zero Trust security. Features like Stateful Switchover (SSO) and Nonstop Forwarding (NSF) ensure high availability in mission-critical networks.
