Re: cat 6500

This performance difference you are talking about is the difference of fabric enabled/fabric-only or non-fabric enabled linecards (legacy) and the higher pps rates do require the SFM which provides the Crossbar function to the fabirc enabled line cards. Here is a very good link to help you out with this information gathering:

See Catalyst 6000 Family Packet Flow—A Day in the Life of a Packet." Section

Hope this helps,

Don
