Cisco Catalyst 4500E Supervisor Engine 7L-E Control Processor

The Cisco WS-X45-SUP7L-E= is a supervisor engine that upgrades a Catalyst 4500E chassis with the performance headroom and visibility today’s enterprise networks require. It delivers a 520 Gbps switching fabric and supplies 48 Gbps of dedicated bandwidth to every slot, so each line card can operate without contention even when traffic surges.

Built-in Flexible NetFlow gives administrators deep insight into applications, users, and flows, which makes it easier to fine-tune security policies or shape traffic with QoS. The engine forwards up to 225 million IPv4 packets per second and 110 million IPv6 packets per second, providing the scale needed as more devices and dual-stack applications appear on the network.

The module includes 2 GB of SDRAM and 1 GB of flash to store large route tables and feature-rich IOS software. Non-Stop Forwarding and Stateful Switchover keep data moving during maintenance or unexpected failovers, while Cisco EnergyWise helps teams monitor and reduce power consumption across the campus.

Installation is straightforward: slide the supervisor into an available slot, power up, and bring the switch back online. Network teams in universities, hospitals, and enterprise campuses often choose this model when they want advanced services such as detailed flow analytics and robust Layer 3 routing without replacing their entire switching infrastructure.

Whether it runs alone in a cost-conscious wiring closet or works in a redundant pair at the core, the Cisco WS-X45-SUP7L-E= provides the balanced mix of throughput, resilience, and operational insight that modern networks need.
