Описание
WS-X6816-10T-2T is 16-port 10 Gigabit Ethernet Copper Module for Cisco Catalyst 6500 E-series switch with exclusively supported by Supervisor Engine 2T. WS-X6816-10T-2T equipped WS-F6K-DFC4-E daughter card in order to deliver optimal performance up to a sustained 60 Mpps for L2, IPv4 and MPLS forwarding and 30 Mpps for IPv6 forwarding. WS-X6816-10T-2T is designed for data center access and switch-to-switch connectivity as well as high-spped server connectivity. Users can configure 4 port groups of 4 ports each, each port group in either oversubscription mode or performance mode, providing the flexibility to use some ports for connection to servers and other ports for interconnection of switches.
