From core to edge, Cisco network switches provide the performance, high availability, comprehensive security, delivery optimization, and enhanced manageability you need to optimize your network infrastructure.

Cisco offers two types of network switches

Modular Switches

Cisco Catalyst modular network switches provide operational simplicity, media flexibility, and expandability to extend deployment life and reduce total ownership costs. Cisco switch products offer high availability, integrated security, strong support for converged applications, and significant long-term investment protection.
