Hello Team,
I am trying to establish Port-Channel from 3850 to Cisco 9K having VPC configuration, but I am getting this error (Peer does not have corresponding vPC) on 9K :-

Hi,
Can you post the configs from the 3850 and the 9ks?

Couple of observation :
your VPC only allowed VLAN 1
1 Po200 up 1
What VLAN allowed in PO 33
is the PO 33 configured both the nexus? and put them VPC?
can you post the Port-channel 33 config from both the nexus also 3850 switches to review?

Hello All,
after design new VPC design, I am getting the same problem:-

There is difference information from the orginal post to new Post - the new post do not have PO30
This look like you are testing this on EVE-NG ( i do believe you have 3850 image available for simulation)
you have IOL or vIOS for testing - if this is EVE-NG
i need to look your show version from nexus device and switch side.
Quick fix is
1. change all from ACTIVE to ON
example :
channel-group 156 on
2. make sure you allowed only required VLAN Nexus vPC or the same will need to be match vPC down to switch.
