Cisco Catalyst 6500 Series 10/100 and 10/100/1000 Modules

Cisco Catalyst 6500 Series 10/100 and 10/100/1000 Ethernet interface modules feature three classes of forwarding

architectures and switch fabric interconnections —Classic, CEF256 and CEF720—provide a choice of speeds and

forwarding rates. Table 3 highlights the key differences in the 3 classes of forwarding / switch fabric architectures.

The WS-X6548-GE-TX and WS-X6548V-GE-TX do not support distributed forwarding; a DFCx can not be

installed on these interface modules.
