Cisco CATALYST 5500 9 PORT GIGABIT ETHERNET SWITCH MODULE 规格指南

state-of-the-art features for network-wide discovery, mapping,

configuration, monitoring, and software distribution services. In

addition, this console is a complement to any Cisco switching or

routing product.

In summary, the Catalyst 5000 Family from Cisco

offers switching solutions that include distribution layer and

server switching for small to medium-sized enterprise networks, as

well as high-density wiring closet switching for large enterprise

networks. The Cisco Catalyst 5000 Family builds on the

award-winning architecture of the Catalyst 5000 while integrating

the Cisco IOS

®

 software-based routing technology. This

combination of best-of-breed technologies creates a powerful

solution for addressing the growing needs of high-performance

networks. The addition of Gigabit Ethernet technology allows

network managers to build wiring closet and distribution-layer

networks using a common and proven architecture.

The Catalyst 5000 supports industry-leading functionality, with

features for scalability, bandwidth management, security services,

network resiliency, and embedded manageability. Highlighted
