Cisco's Catalyst 5000 family switching solutions focused on the needs of high-performance wiring closets for large enterprises. Supervisor II engine ports on 10/100 ports on Fast EtherChannel-capable line cards enable high-speed connectivity between switches, switches and routers, and switches and servers. They can be grouped to provide even higher bandwidth for load-sharing, redundant, and point-to-point connections between the Catalyst 5000 family switches.
