•
Base forwarding mode and performance—Uses the central CEF engine located on the supervisor engine to forward packets up to 30 Mpps per
system in its base configuration
•
Distributed forwarding upgrade option and performance—When equipped with the optional field-upgradeable WS-F6700-DFC3 dCEF
forwarding daughter cards, the interface module delivers optimal performance, up to a sustained 48 Mpps per slot (26 Mpps per slot for
WS-X6724-SFP)
•
Optics—Support hot-pluggable modular small form-factor pluggable (SFP)
Inline power support is not supported on mixed media Gigabit Ethernet interface modules.

CISCO CATALYST 6500 SERIES DCEF256 GIGABIT ETHERNET MIXED MEDIA INTERFACE MODULES
Designed for distribution and core layers and for data-center and Web-hosting applications, Cisco Catalyst 6500 series dCEF256 optical interface
modules provide line-rate Gigabit Ethernet forwarding with the following operational advantages:
•
Backplane connection—Uses dual 8-Gbps (16Gbps) full-duplex serial channel connections to the switch fabric on a Supervisor Engine 720 or
a SFM/SFM2 module
•
Slot requirements—Can occupy any slot in any Cisco Catalyst 6500 Series chassis except the 6513 chassis which requires installation in slots
9 through 13 (the only slots on the chassis with dual fabric connections)
•
Supervisor engine—Supports Supervisor Engine 2 with a SFM or all versions of Supervisor Engine 720
