Joined a pair of 92K switches in a VPC domain. I receive the following below. Anyone know what may be wrong as I checked both switches and everything looks the same?

Configuration inconsistency reason: vPC type-1 configuration incompatible - STP

 

 

vPC domain id : 10
Peer status : peer adjacency formed ok
vPC keep-alive status : peer is alive
Configuration consistency status : failed
Per-vlan consistency status : success
Configuration inconsistency reason: vPC type-1 configuration incompatible - STP
global port type inconsistent
Type-2 inconsistency reason : Consistency Check Not Performed
vPC role : secondary
Number of vPCs configured : 0
Peer Gateway : Enabled
Dual-active excluded VLANs : 252
Graceful Consistency Check : Enabled
Auto-recovery status : Enabled, timer is off.(timeout = 360s)
Delay-restore status : Timer is off.(timeout = 150s)
Delay-restore SVI status : Timer is off.(timeout = 10s)
Operational Layer3 Peer-router : Disabled

 

 

So I notice on show consistency vpc global... I got the following on one switch but I don't see what is different between them to change them both to normal. ANy help??

Looks like one of the vPC legs you have a port configured as port type network and edge.
make sure the spanning-tree port type is matching for all vPC interfaces

Check all your interfaces that are part of the vPC and make sure they are the same (spanning-tree port type, etc.)
