Actually, both are "fabric-enabled." In the main 65xx box you have the 32Gb/s backplane (BUS) and now you can also take advantage of the "Switch Fabric" to bump your capacity up to 256Gb/s. Regarding the different 16-port GBIC cards you have three options:
6416 - BUS-only (32Gb/s) - SUP handles all packet forwarding 6516 - BUS and fabric (single fabric attachment) (up to 256Gb/s*) - SUP handles forwarding by default but an optional daughter card can be added to upgrade to dCEF. 6816 - fabric only (dual fabric attachments) (256Gb/s) - dCEF only; integrated daughter card. Here's a link that talks more about the different options: http://cco.cisco.com/warp/public/cc/pd/si/casi/ca6000/prodlit/c60ge_ds.htm Obviously, to take advantage of the switch fabric you need SFMs (Switch Fabric Modules) in the chassis (two to be redundant). * I seem to recall when these products were introduced to me by our local Cisco team someone said that the 6500-series cards (for the 6500-series chassis, it's a bit confusing - you'd think they could use another number) - e.g. 6516 listed above - were only capable of doing 128Gb/s because they were only attached to a single switch fabric and that to do the full 256Gb/s you'd need the fabric-only cards (the 6800-series modules). Just looking really quick, I don't see any docs on CCO that substantiate my memory so if it matters to you, you might want to ask Cisco - perhaps my memory is incorrect or I was given bum scoop from our Cisco reps.

The module has integrated distributed forwarding and has dual serial connections to the switch fabric module. The module requires GBICs. GBICs are available in three models (SX, LX/LH, and ZX) and have an SC-type connector for use with either MMF and SMF. What is mean by the " fabric-enable Gigabit Ethernet switching module " ??
