whether you run an L2 'edge' port as FabricPath or classical ethernet (e.g. STP) does not change the features that can be enabled on that port.
yes, you can use any of what you suggest with FP.  its orthogonal.

generally speaking, feature availability depends on the capabilities of the forwarding engine operating the port (e.g. what the M1 I/O module forwarding engine supports or F1 I/O module forwarding engine), not whether a VLAN exists within the space of FabricPath or Classical Ethernet.

i don't know either.  i can't see why docs state vPC peer-switch is not recommended.


cheers,
