About Cisco enterprise LAN switches

The Cisco Catalyst and Nexus campus LAN switches are flexible in scale and port speed. Our fixed and modular, core and access LAN switches have been designed for an entirely new era of network architecture. Now your network can learn, adapt, and evolve.

An intuitive network recognizes your intent, mitigates threats through segmentation and encryption, and learns and changes over time. You can unlock opportunities, enhance security, improve business agility, and dramatically increase operational efficiencies.

Our Catalyst network switches are a core part of an integrated security architecture that works before, during, and after a threat occurs to reduce attack surface, detect malware and threats, and rapidly contain those threats.
