See the attached for the best practice for vPCs. Taken from the vPC Best Practicies guide (supplied to me by Reza). It is for N7Ks but as far as i am aware the same principles apply.

spanning-tree port type edge should apply to all access/trunk ports on the FEX. 


Basically, any port that connects to end devices should have it.

Sorry, it got chopped...... Should the vPCs on the Nexus have "spanning-tree port type edge" enabled?

If you mean on the N5Ks then if these are your aggregation layer switches then no, the port type should be normal and it is recommended to enable rootguard on these ports that face the access layer switches.


The uplinks from the FEX should also be normal ports but no rootguard configured.

They aren't conflicting. Reza was talking about end devices connecting to the FEX  and i was talking about the connections between the FEX and the N5Ks.


Apologies Reza if i have misrepresented what you were saying.
