Cisco Catalyst 6500 Series CEF720 Gigabit Ethernet Mixed Media Modules
Designed for high performance Enterprise and Service Provider distribution, core layers, data-
center, Web-hosting and Metro Ethernet applications, CEF720 mixed media interface modules
provide line-rate gigabit Ethernet forwarding using twisted pair or fiber optic cabling with the
following operational advantages:
●
Backplane connection: Connects to the switch fabric using dual full duplex 20 Gbps
switch fabric channels (40 Gbps total), a single 20 Gbps channel is supported by the WS-
X6724-SFP
●
Chassis/slot support: Can occupy any slot in Cisco Catalyst 6503E, 6504E, 6506,
6506E, 6509, 6509E, and 6509-NEB-A and slots 9 through 13 in Catalyst 6513; the WS
X6724-SFP module is supported in all slots of the Catalyst 6513
●
Supervisor engine: Supported by all versions of Supervisor Engine 720
●
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)
Note:
Inline power support is not supported on mixed media Gigabit Ethernet interface modules.
