WS-X6816-10T-2T Cisco Catalyst 6800 16-Port 10 Gigabit Ethernet Copper Module

The WS-X6816-10T-2T is a Cisco Catalyst 6800 Series 16-port 10 Gigabit Ethernet copper module with a DFC4 forwarding card. It carries 16 10GBASE-T ports on RJ-45 connectors for server access and for switch-to-switch links inside 100 m. Category 6 UTP runs up to 55 m; Category 6 STP, Category 6A UTP and STP, and Category 7 STP run up to 100 m.

The module connects to the switch fabric through two 20 Gbps full-duplex channels, 40 Gbps in total. In oversubscription mode the 16 ports share that capacity at 4:1. In performance mode, 4 ports run at 1:1, and those ports can form a virtual switch link of up to 4 ports.

The DFC4 on this 2T model holds 256K forwarding entries, 64K ACL entries and 512K NetFlow entries. The WS-X6816-10T-2TXL version steps those up to 1 million, 256K and 1024K. Both reach 60 Mpps for IPv4 and 30 Mpps for IPv6, with a 128K MAC address table, 16K bridge domains and jumbo frames up to 9216 bytes. Onboard memory is 1 GB.

The module fits Catalyst 6500 E-Series chassis only: 6503-E, 6504-E, 6506-E, 6509-E, 6509-V-E and 6513-E, with Supervisor Engine 2T or 2TXL. It takes any slot in the 6503-E through 6509-V-E, and slots 1 to 6 and 9 to 13 in the 6513-E. It is not supported in non-E chassis.

Other Catalyst 6800 line cards on the site include the WS-X6816-10G-2T 16-port X2 module and the C6800-8P10G 8-port module, and more modules are in Cisco switches.

Power draw is 514.96 W. The module occupies one slot and measures 1.2 x 14.4 x 16 in (3.0 x 35.6 x 40.6 cm), weighing 13.6 lb.
