A multinational enterprise deploys the WS-SUP720-3B Supervisor 720 (MSFC3/PFC3B) in Catalyst 6500/Cisco 7600 chassis at its campus core to deliver redundant control-plane, hitless software upgrades, and sub-millisecond backplane failover. Outcome: 99.999% uptime, seamless scalability across thousands of VLANs, and optimized BGP/OSPF convergence for real-time business applications.
A cloud service provider leverages the Supervisor 720 Fabric (MSFC3/PFC3B) in Catalyst 6500 aggregation switches to consolidate multiple 10/40 GbE uplinks, enforce per-flow QoS and traffic policing at line rate, and integrate with Cisco TrustSec for micro-segmentation. Outcome: Deterministic latency, accelerated VM mobility, and consistent SLAs for mission-critical workloads.
An educational institution implements WS-SUP720-3B in its Cisco 7600 edge routers to enable VRF-lite segmentation, dynamic route redistribution via MSFC3, and scalable security policies using PFC3B. Outcome: Simplified multi-tenant isolation, automated compliance enforcement, and capacity to support thousands of connected devices with granular access controls.
