In a multi-building corporate campus supporting 20,000+ users, IT deploys the Cisco Catalyst 9400 Series Supervisor 1 (C9400-SUP-1) to enforce granular VLANs, dynamic access policies, and role-based segmentation. By leveraging its 40-Gbps fabric gains and advanced TrustSec integration, the organization isolates sensitive departments (finance, R&D) without compromising performance. Outcome: 50% faster policy provisioning, zero downtime during reconfiguration, and end-to-end security enforcement across 1,000+ access ports.
A global bank’s data center requires five-nines uptime and seamless failover at the access layer. Integrating C9400-SUP-1 modules in redundant Supervisor pairs delivers stateful switchover and nonstop forwarding for critical trading applications. The design supports 480 Gbps of distributed switching capacity and real-time synchronization of VXLAN and MPLS EVPN overlays. Outcome: Under-50 ms failover, guaranteed transaction continuity, and 99.999% availability for latency-sensitive financial workloads.
A Tier 1 automotive plant deploys thousands of IoT sensors and Wi-Fi 6 access points to monitor robotics, inventory, and environmental controls. The C9400-SUP-1 module provides 16-slot redundancy, embedded wireless controller support, and 10-Gbps uplinks to edge switches. With automated QoS, microsegmentation, and telemetry telemetry via Cisco DNA Center, operations gain real-time visibility and secure device onboarding. Outcome: 30% improvement in production throughput, 40% reduction in network MTTR, and future-proof capacity for 5G factory rollout.
