Cisco Express Forwarding 720 10/100/1000 Interface Module (part number WS-X6748-GE-TX)
with Distributed Cisco Express Forwarding Daughter Card (part number WS-F6700-DFC3A)
Cisco Catalyst 6500 Series Cisco Express Forwarding 256 10/100 and 10/100/1000
Interface Modules
Designed for premier wiring closets, small campus backbone, and server farm applications,
Cisco Express Forwarding 256 10/100 and 10/100/1000 Ethernet-over-copper interface modules
provide line-rate 10/100 Ethernet forwarding and gigabit bandwidth options. (Refer to Table 4).
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.
