The WS-X6908-10G-2T is the DFC4 model of the Cisco Catalyst 6900 Series 8-port 10 Gigabit Ethernet module. Its DFC4 card carries 256K forwarding entries, 64K ACL entries and 512K NetFlow entries, and forwards IPv4 at 60 Mpps. The ports require X2 optics.
Each port is backed by 256 MB of buffer, and the card has an 80-Gbps full-duplex fabric connection with 1:1 oversubscription. Receive queues are 8q4t, transmit queues are 1p7q4t, and jumbo frames reach 9216 bytes. TrustSec and IEEE 802.1ae encryption in hardware are supported, and every port can be used to build a virtual switch link.
This card needs Supervisor Engine 2T or 2TXL and an E-Series chassis: 6503-E, 6504-E, 6506-E, 6509-E, 6509-V-E or 6513-E. A non-E chassis is not supported. In a 6513-E the usable slots are 1 to 6 and 9 to 13. Port density is 64 in a 6509-E and 88 in a 6513-E, or 128 and 176 per virtual switching system. Onboard memory is 2 GB.
Maximum power draw is 588 W. Cisco IOS software reports the card as WS-X6908-10GE carrying a WS-F6K-DFC4-E, and the front panel is labeled WS-X6908-10GE-2T.
For a 16-port 10 Gigabit option see the WS-X6816-10G-2T 16-port 10 Gigabit module; the Cisco switch category covers further Catalyst modules.
