WS-C6503-E Use Case
High-Performance Campus Core Aggregation with WS-C6503-E
Scenario: A large enterprise campus deploys the WS-C6503-E Catalyst 6500 Enhanced 3-slot chassis (4RU, no PS, no Fan Tray) with Supervisor Engine 2T and multi-rate line cards as the core aggregation switch. This modular platform delivers up to 720 Gbps of non-blocking throughput and hot-swappable expansion. Benefit: Simplified network scaling, high availability and reduced operational complexity in a compact chassis.
Carrier-Grade Service Provider Edge with MPLS and QoS
Scenario: A regional service provider uses the WS-C6503-E chassis for edge routing in a metro POP, pairing an MPLS-enabled Supervisor Engine SE2 with high-density line cards to aggregate up to 96 customer circuits. The 4RU chassis supports hot-swappable power and cooling modules for pay-as-you-grow deployment. Benefit: Scalable port density, carrier-grade QoS enforcement and seamless multi-tenant service roll-out on a single platform.
Data Center Virtualization Fabric via Virtual Switching System
Scenario: In a virtualized data center, two WS-C6503-E chassis operate in Virtual Switching System (VSS) mode to form one logical Catalyst 6500 Enhanced switch, enabling active-active redundancy and dynamic workload mobility. Benefit: Zero-loss failover, optimized bandwidth utilization and streamlined maintenance within a resilient, compact 4RU footprint.
