In a global cloud provider environment, the WS-SUP720-3BXL in Catalyst 6500/Cisco 7600 chassis delivers nonstop L3 forwarding via Fabric MSFC3 and PFC3BXL-based hitless supervisor switchover. This ensures 99.999% uptime, sub-millisecond routing convergence, and seamless stateful redundancy across dual supervisors. Outcome: maximized business continuity, predictable performance under peak loads, and simplified maintenance windows.
A large financial services campus uses the WS-SUP720-3BXL to enforce dynamic VLAN segmentation, advanced QoS policies, and Identity-Based Networking Services (IBNS) on Catalyst 6500 switches. Fabric-based forwarding offloads policy enforcement, while MSFC3 integration centralizes security policy and routing. Outcome: guaranteed application performance, granular access control, and reduced operational complexity for thousands of endpoints.
A Tier-1 service provider deploys the WS-SUP720-3BXL on Cisco 7600 to run high-scale MPLS VPN, multicast, and IPv6 peering services. PFC3BXL hardware forwarding scales to 720 Gbps, BGP Route Reflector and LDP/MPLS TE integrate with MSFC3 for optimal path selection. Outcome: multi-tenant isolation, consistent SLA delivery, and flexible expansion without forklift upgrades.
