The WS-X6904-40G-2T is the Cisco Catalyst 6900 Series 4-Port 40 Gigabit Ethernet Fiber Module with DFC4. It offers four 40G ports or sixteen 10G ports, and the spare is WS-X6904-40G-2T=. The 40G optics are CFP-40G-SR4 (100 m over OM3 multimode) and CFP-40G-LR4 (10 km over single-mode).
A CVR-CFP-4SFP10G FourX converter turns each 40G port into four SFP+ ports. EtherChannel can bundle up to four 40G links, or up to eight 10G ports in 10G mode.
The module connects to the switch fabric at 80 Gbps full duplex. Oversubscription is 2:1 in the default mode and 1:1 in performance mode. Forwarding on the default DFC4-E reaches 60 mpps for IPv4 and up to 30 mpps for GRE, IPv6 and VPLS, with 256K forwarding entries, 64K ACL entries, a 128K MAC table and 512K NetFlow entries. A swap to a DFC4XL moves it to XL scale.
Layer 2 and Layer 3 Cisco TrustSec and IEEE 802.1ae MACsec encryption run in hardware. Jumbo frames go up to 9216 bytes, and VSL is supported on all ports with a maximum of four 40G ports.
It fits any Catalyst 6500 E-Series chassis, in any slot of a 6503-E, 6504-E, 6506-E, 6509-E or 6509-V-E and in slots 1-6 and 9-13 of a 6513-E. It weighs 12 lb without CFPs, draws 468 W and carries 2 GB of onboard memory. See the C6800-8P10G and other cards in the Cisco interface cards range.
