Product Review

The Cisco WS-X6708-10G-3C module offers eight 10GbE ports with X2 optics, providing high-density connectivity and a 40 Gbps switch fabric connection, aligning well with high-performance networking demands. The module supports a 1:1 oversubscription rate and comes equipped with a DFC3C for distributed forwarding, enabling efficient handling of up to 256,000 forwarding entries and advanced queuing mechanisms, which enhances network traffic management. However, its power requirement of 444.36 W and the need for a compatible Cisco Catalyst 6500 E-Series chassis may limit its deployment flexibility in environments not already using Cisco infrastructure or those sensitive to power consumption.

Overview

The Cisco WS-X6708-10G-3C is a high-performance module designed for the Cisco Catalyst 6500 E-Series chassis, offering advanced features tailored for demanding network environments. This module comes equipped with eight Gigabit Ethernet ports, utilizing X2 optics for superior data transmission capabilities. It is designed to facilitate a seamless 40 Gbps switch fabric connection, ensuring efficient handling of data across the network. Notably, this module operates with a 1:1 oversubscription rate, indicating a balanced approach between port density and throughput performance. At the heart of its operation, the WS-X6708-10G-3C features a Distributed Forwarding Card (DFC3C), enhancing its ability to process and forward data with precision. This card supports a substantial number of forwarding entries, up to 256,000, allowing for extensive network segmentation and efficient data routing. The module's sophisticated queuing mechanism is designed to prioritize data packets based on Class of Service (CoS) and Differentiated Services Code Point (DSCP), ensuring that critical information is delivered promptly and reliably. The scheduling capabilities of this module are robust, including Deficit Weighted Round Robin (DWRR), Weighted Random Early Detection (WRED), and Shaped Round Robin (SRR) at egress. These features work together to optimize the flow of data, preventing congestion and maintaining quality of service across the network. Additionally, each port on the WS-X6708-10G-3C is equipped with 200 MB of buffer space, and the module supports jumbo frames up to 9216 bytes, facilitating the efficient transmission of large data packets.
  • Maximum port density reaches 66 ports in a 9-slot chassis and doubles to 132 ports in a Virtual Switching System (VSS) configuration.
  • Compatible with Cisco Catalyst 6500 Series Virtual Switching Supervisor Engine 720, it offers flexibility in network design and scalability.
  • Equipped with 1 GB of onboard memory, enhancing its processing capabilities to handle extensive network demands.
The physical specifications include a height of 1.2 inches, width of 14.4 inches, and depth of 16 inches, weighing 13 lbs. This module operates efficiently within a temperature range of 0 °C to 55 °C and can be stored in temperatures ranging from -40 °C to 75 °C. It is designed to work reliably in environments with relative humidity ranging from 10% to 90% (non-condensing) and at altitudes from –500 to 10,000 feet. Powering the WS-X6708-10G-3C requires 444.36 W, ensuring that the module performs optimally while managing its energy consumption effectively. The module also includes indicators for status and link activity, providing immediate visual feedback on the operational state and connectivity of each port. In summary, the Cisco WS-X6708-10G-3C is a versatile and powerful module designed for high-density networking environments. It offers advanced features for data forwarding, queuing, and scheduling, supported by significant port densities and compatibility with a range of Cisco Catalyst 6500 Series chassis and Supervisor Engines. This makes it an ideal choice for organizations looking to enhance their network's performance, reliability, and scalability.
