WS-X6708-10G-3CXL Overview
Cisco 7600 Ethernet Module / Catalyst 6500 8 port 10 Gigabit Ethernet module with DFC3CXL (req. X2).
There are two versions of the Catalyst 6500 8-port 10 Gigabit Ethernet module:
• 8-port 10 Gigabit Ethernet module with Distributed Forwarding Card 3C (DFC3C)
• 8-port 10 Gigabit Ethernet module with Distributed Forwarding Card 3C (DFC3CXL)
Both modules contain the WS-X6708-10GE base board and a distributed forwarding card. The base module supports up to eight pluggable X2 optics and has a 40 Gbps connection to the fabric and is therefore 2:1 oversubscribed. The distributed forwarding card provides hardware-based MAC learning and forwards traffic at 48 Mpps. The 8-port 10 Gigabit Ethernet module can demonstrate 60 Gbps local switching. Besides increased port density, it also has increased port buffering and enhanced queuing and scheduling mechanisms for congestion management.
