The WS-X6848-TX-2T is a Cisco Catalyst 6800 Series 48-port copper Gigabit Ethernet module with a DFC4 distributed forwarding card. Its ports are RJ-45 for 10/100/1000 over Category 5 cable up to 100 m, and the DFC4 handles Layer 2, IPv4 and MPLS forwarding at a sustained 60 Mpps and IPv6 at 30 Mpps.
The module reaches the switch fabric over dual full-duplex 20-Gbps channels, 40 Gbps in total. It works only with Supervisor Engine 2T or 2TXL. Slots 1 to 6 and 9 to 13 are usable in a 6513-E, and any slot in a 6503-E, 6504-E, 6506-E, 6509-E or 6509-V-E, giving up to 384 ports in a 6509-E and 528 in a 6513-E.
Each port has Tx 1p3q8t and Rx 2q8t queues with DWRR scheduling, and buffering of 166 KB receive and 1.17 MB transmit. Jumbo frames go up to 9216 bytes, and 1 GB of onboard memory is fitted by default. Maximum power draw is 405 W.
Cisco IOS software reports this card as WS-X6848-TX together with a WS-F6K-DFC4-E, while the front panel carries the full WS-X6848-TX-2T label. Status and link LEDs indicate module and port status.
The XL-class twin is the WS-X6848-TX-2TXL 48-port copper module, and more of the family sits in the Cisco switch modules.
