A fundamental component of a corporate network is the LAN switching infrastructure, which connects users, applications, and communication systems with one another. Since 1995, Cisco Systems has been a leader in LAN switching innovation, from the introduction of the Catalyst 5000 series to the development of today's intelligent switch platforms. Cisco Catalyst LAN switches provide intelligence and performance at the highest technological standards and support corporate goals through the protection, optimization, and scalability of the infrastructure.
