Cisco Catalyst Core, Aggregation, and Controller Switches - Refurbished, Used, New

Cisco Catalyst Core, Aggregation, and Controller switches form the backbone of enterprise and campus networks, delivering the performance, resiliency, and scalability required for mission-critical environments. This section highlights platforms designed for data center fabrics, enterprise cores, and large-scale wireless control.

For high-speed distribution and backbone roles, the Cisco Catalyst 9500 Series delivers advanced core aggregation in a fixed form factor, while the Cisco Catalyst 9600 Series provides modular enterprise core capacity with multi-terabit throughput. The Cisco Catalyst 9800 Wireless Controllers unify policy, security, and automation for Wi-Fi 6 and Wi-Fi 6E deployments, extending visibility across wired and wireless networks.

Legacy and proven systems remain essential for many enterprises. The Cisco Catalyst 4500X provides compact fixed-core functionality, and the Catalyst 4900 offers server access in dense data center environments. Larger modular chassis like the Cisco Catalyst 6500 and Catalyst 6800 families continue to anchor campus core networks with flexibility, high availability, and advanced feature support.

Branch and edge connectivity is supported by the Cisco Catalyst 8200 Series Edge Platforms and Catalyst 8300 Series, which integrate routing, security, and SD-WAN for distributed enterprise deployments. Together, these platforms extend Cisco’s enterprise-class features from the core to the edge.
