Cisco WS-X6748-GE-TX, Catalyst 6500 Series 48-Port 10/100/1000 RJ-45 Cisco Express Forwarding 720 Interface Module; field-upgradable to support distributed forwarding with the addition of the distributed forwarding daughter card (part number WS-F6700-DFC
Designed to complement the many roles that the Cisco Catalyst 6500 Series plays in a network, Cisco Catalyst 6500 Series mixed media Gigabit Ethernet modules offer the broadest selection of media, densities, performance, interoperability, and chassis deployments for enterprises and service providers. These modules are ideal for gigabit Ethernet over fiber to the desktop, gigabit uplinks, aggregation of high-density 10/100 interfaces, Metro Ethernet, backbone and high-speed server farm or data center connections as well as mixed media environments supporting both fiber and copper cable connections. The Cisco Catalyst 6500 Series Gigabit Ethernet modules offer:
Designed for high-performance enterprise and service provider distribution, core layers, data-center, and Web-hosting applications where voice capability is not required, Cisco Express Forwarding 720 twisted-pair interface modules provide line-rate 10/100/1000 Ethernet forwarding with the following operational advantages.
• Forwarding architecture: These modules use the central Cisco Express Forwarding engine located on the supervisor engine; optional field-upgradable Distributed Cisco Express Forwarding daughter cards are available.
• Forwarding performance: These modules forward packets up to 30 Mpps per system; they forward packets up to sustained 48 Mpps per slot for slots equipped with distributed forwarding cards (DFC or DFC3).
• Fabric connection: These modules connect to the switch-fabric channels using dual 20 Gbps switch-fabric channels (40 Gbps total).
• Supervisor engine: These modules work with Supervisor Engine 720.
• Distributed forwarding upgrade option: These modules help enable full locally distributed forwarding; they use an optional (part number WS-F6700-DFC3) upgrade to operate with the Supervisor Engine 720, and they provide optimal interface module performance.
• Slot and chassis requirements: These modules can occupy any slot in the Cisco Catalyst 6506, Catalyst 6509, Catalyst 6509-NEB, or Catalyst 6509-NEB-A; they require slots 9 through 13 when used in the Cisco Catalyst 6513. Cisco Catalyst 6503 support is under consideration for the future (refer to release notes for details).
• Maximum port density per chassis: These modules support up to 384 ports per Cisco Catalyst 6509, up to 240 Cisco Express Forwarding-based ports, and an additional 336 classic or Cisco Express Forwarding 256-based ports per Cisco Catalyst 6513.
Note: PoE is not supported on Cisco Express Forwarding 720 10/100/1000 interface modules.
