I did not take logs of those switches. Can you compare configuration and check any issue in configuration.

[MHM Cisco World]

You  use PO for keepalive and it config as router port and port member of this PO you dont use no switchport?

Are you sure you can ping via peer-keepalive interface??

Hello
you vpc cfg looks okay, however you do have inconsistencies of either switch ( see attached file)

Also you could try deleting vpc-peer-link PO2 and defaulting their related ports (eth1/53-54) and then recreate the PC but let it be created automatically.

uploaded configuration are in production environment. we are replacing with new switches due to end of life existing switch. i have configure same configuration as old devices configured. what will be issue 

[paul driver]

Hello
so you need to make sure you have consistency on the vpc 
Which you do not have at present -also you are saying the peer-link is down so my suggestion is to re-create is as stated in the file i sent you  and sort out the consistency also shown in that file

@amit.sharma The issue of the vPC being suspended when connecting the peer link cable is likely due to a mismatch in the configurations on the two Nexus switches. Check that both switches have consistent vPC domain IDs, the same port-channel numbers for the vPC peer link, identical interface settings (speed, duplex, MTU), and matching VLAN configurations. Additionally, ensure the peer-keepalive is properly configured and reachable. Fixing these mismatches should resolve the suspension.
