In a multinational corporation’s campus network, deploying dual C9400-SUP-1XL/2 Cisco Catalyst 9400 Series Redundant Supervisor 1XL Modules in active-standby mode ensures uninterrupted Layer 3 routing and policy enforcement during supervisor firmware upgrades or unexpected failures. Benefit: Achieve five-nines (99.999%) network availability and eliminate unplanned downtime, enabling continuous business operations and seamless user experience.
A financial services data center uses two C9400-SUP-1XL/2 supervisors in a stack of Catalyst 9400 switches to support latency-sensitive trading platforms and real-time analytics. The redundant supervisor architecture automatically fails over in milliseconds if the active module loses power or experiences hardware faults. Benefit: Maintain ultra-low latency and guaranteed packet forwarding, protecting SLA-driven applications and preserving revenue-critical performance.
An Internet service provider deploys Catalyst 9400 Series switches with paired C9400-SUP-1XL/2 supervisors at the network edge to host virtualized network functions for broadband subscribers. The redundant supervisors leverage Stateful Switchover (SSO) and Non-Stop Forwarding (NSF) to preserve BGP sessions and MPLS forwarding tables during maintenance. Benefit: Increase subscriber uptime, accelerate service provisioning, and reduce operational complexity through in-service software upgrades without traffic interruption.
