Hi, as you can see from the

Hi, as you can see from the output of "show vpc" the Type-2 consistency check not performed. It is probably due to you have not configured any type-2 consistency check related features on your devices that would triggers the type-2 inconsistency check to perform.

You can read more about type-2 consistency parameters here:

Thank you !! : )

Hi,Please check if you have

Hi,

Please check if you have any SVI configured on both Peer devices. if there is no any SVI configured the type 2 consistency check will not perform. So this is expected behaviour if we don't have SVI configured on both switches.

To verify this , please give me below ouput 

show ip int brief | ex unas

or you can create SVI on both device and test it.

Hi,

Hi,

We faced similar issue in N9K.

We enabled feature interface-vlan after which we got type-2 consistency status : Success

Now i disabled feature interface-vlan and still we see type-2 consistency status : Success
