WS-X6708-10G-3C Cisco Catalyst 6500 8-Port 10 GB Ethernet Module w/ DFC3C
Cisco WS-X6708-10G-3C Catalyst 6500 8-Port 10 Gigabit Ethernet Module with DFC3C
Enterprise Cisco Catalyst 6500 8-Port 10 Gigabit Ethernet Module with DFC3C for High-Performance Core and Data Center Networking
The Cisco WS-X6708-10G-3C 10 Gigabit Ethernet Interface Module is a high-performance line card designed for Cisco Catalyst 6500 Series switches and Cisco 7600 Series routers. Featuring 8 X2-based 10 Gigabit Ethernet ports and an integrated Distributed Forwarding Card 3C (DFC3C), it delivers wire-speed Layer 2 and Layer 3 forwarding for enterprise core, data center, campus backbone, and service provider networks.
Equipped with 8 high-speed X2 transceiver slots, the WS-X6708-10G-3C supports a wide range of Cisco 10 Gigabit Ethernet X2 optical transceivers, including SR, LR, ER, LRM, and CX4 modules. This flexibility enables organizations to deploy high-bandwidth fiber connectivity across short-, medium-, and long-distance network links.
The integrated DFC3C forwarding engine provides Distributed Cisco Express Forwarding (dCEF), allowing packet forwarding to be processed directly on the line card rather than relying solely on the supervisor engine. This distributed architecture enhances system scalability, reduces latency, and improves overall switching performance in high-density network environments.
The module supports wire-speed Layer 2 and Layer 3 switching and integrates seamlessly with compatible Cisco Catalyst 6500 and Cisco 7600 platforms. Advanced networking capabilities include IPv4, IPv6, IEEE 802.1Q VLANs, inter-VLAN routing, hardware-based Access Control Lists (ACLs), Quality of Service (QoS), multicast, EtherChannel, IEEE 802.3ad Link Aggregation (LACP), jumbo frames, and Distributed Cisco Express Forwarding, depending on the installed supervisor engine and Cisco IOS software.
Featuring a 40 Gbps switch fabric connection, the WS-X6708-10G-3C provides high-bandwidth communication with the host chassis while maintaining consistent low-latency performance. Its hot-swappable modular design enables installation, replacement, and maintenance with minimal impact on network availability.
Ideal for enterprise core networks, data center aggregation, campus backbone connectivity, service provider infrastructure, high-speed server connectivity, and network expansion projects, the Cisco WS-X6708-10G-3C 8-Port 10 Gigabit Ethernet X2 Interface Module delivers scalable performance, distributed hardware forwarding, and reliable high-speed connectivity for mission-critical networking environments.
