Cisco Systems® announces a new 8-port 10 Gigabit Ethernet module for the Cisco® Catalyst® 6500 Series. The 8-port 10 Gigabit Ethernet module doubles the 10 Gigabit Ethernet density on the Catalyst 6500 Series, providing up to 64 ports of 10 Gigabit Ethernet in a single Catalyst 6500 chassis. It is ideal for deployment in the data center for aggregating bandwidth from servers and in the LAN distribution layer for consolidating uplinks from the LAN access layer. Cisco is also announcing a price drop of the LX4 and SR X2 modular optics. This reduces per port 10 Gigabit Ethernet pricing by 30 percent, bringing this to a new price/performance level of 10 times the bandwidth at just 5 times the price of Gigabit Ethernet. The new 8-port 10 Gigabit Ethernet module complements the existing integrated services on the Catalyst 6500 Series, enabling customers to build a scalable, resilient, and manageable data center to meet their growing business needs to consolidate and virtualize servers and storage to maximize resource utilization and drive down capital expenses.
Cisco data center switching delivers relentless velocity:
• Architecture scalability supports growth in any direction.
• Operational speed increases service velocity and IT staff productivity.
• Comprehensive resilience addresses many sources of downtime.
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 up to 64 Gbps local switching. Besides increased port density, it also has increased port buffering and enhanced queuing and scheduling mechanisms for congestion management. See Table 1 for new features and benefits provided by the 8-port 10 Gigabit Ethernet module and Table 2 for differences between the DFC3C and the DFC3CXL.

The 8-port 10 Gigabit Ethernet module is supported in the Catalyst 6500 Series chassis as well as Cisco 7600 Series Routers. When operating in an E-Series chassis (6503-E, 6504-E, 6506-E, 6509-E), the 6509-NEB-A chassis with dual fan tray, or 7604 chassis or 7609 chassis with dual fan tray, the configuration is NEBS 3 compliant (supports operating temperatures up to 55°C). When operating in a non-E-Series chassis (6506, 6509, 6513) or 6509-NEB-A with single fan tray, 7606/7613 chassis, or 7609 with single fan tray, fan tray 2 and 2500W or higher power supplies are required, and the configuration is not NEBS 3 compliant (supports operating temperatures up to 40°C only). The module can be deployed in all slots of a 3/4/6/9-slot chassis. When operating in a 13-slot chassis, it must be deployed in slots 9-13. It is not supported in the 6503 non-E Series chassis.
The 8-port 10 Gigabit Ethernet module is interoperable with all models of the Cisco Catalyst 6500 Series Supervisor Engine 720, including WS-Sup720, WS-Sup720-3B, and WS-Sup720-3BXL. When mixing DFCs in the same chassis, the chassis will operate in the mode of the lowest common denominator.
The following optics will be supported on the 8-port 10 Gigabit Ethernet module at FCS: X2-10GB-SR, X2-10GB-LR, X2-10GB-ER, X2-10GB-LX4, X2-10GB-CX4. Only the -02 version or later of these optics will be supported on this 8-port 10 Gigabit Ethernet module. The -01 version of the optics is not supported. The SR optics provide 26m over FDDI-grade multimode fiber and are ideal for deployment in data center for server aggregation. The LX4 optics provide 300m over multimode fiber and are ideal for deployment in campus LAN uplinks.
Both versions of the 8-port 10 Gigabit Ethernet module are supported today in both Cisco IOS
® Software and Cisco IOS Software Modularity.
