Cisco WS-F6700-DFC3C : Catalyst 6500 Dist Fwd Card for WS-X67xx modules

The PoE Cisco Express Forwarding 256 10/100/1000 interface modules provide flexible 10-, 100-, and 1000-Mbps access to the desktop through standard RJ-45 connectors. These interface modules feature PoE field-installable daughter cards for pay-as-you-grow investment protection and flexibility. Purposefully designed for the wiring closet with 8:1 oversubscription, these 10/100/1000 interface modules cannot be equipped with distributed forwarding cards.
Offered with a choice of RJ-45 and RJ-21 connectors, the data-only Cisco Express Forwarding 256 10/100 and 16-port 10/100/1000 Ethernet interface modules can be deployed where PoE capability is not required, and they can be equipped with distributed forwarding daughter cards for higher-performance local packet-forwarding environments.
The Cisco Catalyst 6500 Series Cisco Express Forwarding 256 10/100 and 10/100/1000 interface modules offer the following operational advantages and characteristics:

• Forwarding architecture: These modules use the central Cisco Express Forwarding engine located on the supervisor engine.

• Forwarding performance: These modules forward packets up to 30 Mpps per system and up to 15 Mpps per slot if upgraded to support distributed forwarding.

• Fabric connection: These modules connect to the switch fabric through one 8-Gbps connection and the 32-Gbps shared bus.

• Supervisor engine: These modules work with Supervisor Engine 1A, Supervisor Engine 2, or Supervisor Engine 720.

• Slot requirements: These modules can occupy any slot in any Cisco Catalyst 6500 Series chassis.

• Maximum port density per chassis (48-port modules): These modules support up to 576 ports per Cisco Catalyst 6513, and up to 384 ports per Cisco Catalyst 6509.

• Maximum port density per chassis (16-port modules): These modules support up to 192 ports per Cisco Catalyst 6513, and up to 128 ports per Cisco Catalyst 6509.
