WS-X6816-10G-2T-RF - Cisco 16-Port 10GbE Fiber Module with DFC4 Expansion Module

Cisco 16-Port 10 Gigabit Ethernet Fiber Module with DFC4 - Expansion module - 10 Gigabit X2 x 16 - refurbished - for P/N: WS-C6503-E-RF, WS-C6504-E=, WS-C6509-E-RF, WS-C6509-V-E, WS-C6509-V-E-RF, WS-C6513-E The 6800 series 16-port 10 Gigabit Ethernet Fiber Module supports IEEE 802.3ad link aggregation and Cisco distributed EtherChannel technology for fault-tolerant connectivity and bandwidth scalability of up to 80 Gbps per EtherChannel connection using any 8 ports in the same chassis. In addition, it supports hardware-based multicast replication, quality of service (QoS), access control lists (ACLs), jumbo frames, and low latency to enable secure and predictable performance for bandwidth-intensive applications. It consists of 4 port groups of 4 ports each. Users can operate 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.
