In the Cisco Nexus 7000 series switches there are several features that are bound to the hardware, meaning that your module selection restricts the features you can run on the switch ports. Thus, here is once again a summarization of the module-dependent features:
Update 20-Apr-2013: Added OTV and LISP, clarified M1 FEX support.
| M1 series | M2 series | F1 series | F2 series | F2e series | |
| L3 features | Yes | Yes | No | Yes | Yes |
| MPLS | Yes | Yes | No | No | No |
| OTV | Yes | Yes | No | No | No |
| LISP | Yes (on 32-port 10G module only) |
No | No | No | No |
| MACsec | Yes | Yes | No | No | Yes (last 8 ports only) |
| FEX support | Yes (on 32-port 10G module only) |
Yes (on 24-port 10G module only) |
No | Yes | Yes |
| FabricPath | No | No | Yes | Yes | Yes |
| FCoE | No | No | Yes | Yes | Yes (XP only) |
| MAC addresses | 128k | 128k | 16k/256k * | 16k/192k * | 16k/192k * |
| Slot bandwidth | 46G/80G | 240G/200G | 230G | 480G | 480G |
* 16k MAC addresses for each SoC (Switch on Chip), 256k/192k MAC addresses per module
Also remember that there are limitations or specific requirements regarding F2 and F2e series modules interoperability with other modules in the same VDC.
