I have a 2 N5Ks connected to a pair of UCS FIs. The 5Ks are running vPC to the FI

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.

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.

What is the question?

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.

hi jon/reza,
where did you get the nexus port drawings? can you give me a link?
my google search only points me to vPC best practice and not on nexus port types.
i'm going to configure N3K and saw a mix of port types in our environment. i want to do it right on this new build.
my questions:
1) do i configure 'normal' for both access switch trunk and for port-channel?
interface Ethernet1/1
description ### SW01 G1/0/23 ###
switchport mode trunk
spanning-tree port type normal
channel-group 1 mode active
interface port-channel1
switchport mode trunk
spanning-tree port type normal
vpc 1
2) do i configure 'edge' or 'edge trunk' for ASA FW inside trunk (FW inside sub-interfaces)?
interface Ethernet1/15
description ### FW01 G0/1 - INSIDE ###
switchport mode trunk
spanning-tree port type edge trunk
