Viewing A Global Type-1 Inconsistency
When a global Type-1 inconsistency occurs, the vPCs on the secondary switch are brought down. The following
example shows this type of inconsistency when there is a spanning-tree mode mismatch.
The example shows how to display the status of the suspended vPC VLANs on the secondary switch:
switch(config)# show vpc
Legend:
(*) - local vPC is down, forwarding via vPC peer-link
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 consistency reason: vPC type-1 configuration incompatible - STP
Mode inconsistent
Type-2 consistency status : success
vPC role : secondary
Number of vPCs configured : 2
Peer Gateway : Disabled
Dual-active excluded VLANs : -
Graceful Consistency Check : Enabled
vPC Peer-link status

The example shows how to display the inconsistent status ( the VLANs on the primary vPC are not suspended)
on the primary switch:
switch(config)# show vpc
Legend:
(*) - local vPC is down, forwarding via vPC peer-link
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 consistency reason: vPC type-1 configuration incompatible - STP Mo

Type-2 consistency status : success
vPC role : primary
Number of vPCs configured : 2
Peer Gateway : Disabled
