I'm trying to setup two Nexus 9300 series switches for a vPC but keep running into an issue. When I run "ping 10.1.1.2 vrf heartbeat it works on both switches with the IP of the other switch. When I do a show vpc brief it says I'm down.
vPC domain id : 200
Peer status : peer link is down
vPC keep-alive status : Suspended (Destination IP not reachable)
Configuration consistency status : failed
Per-vlan consistency status : success
Configuration inconsistency reason: Consistency Check Not Performed
Type-2 inconsistency reason : Consistency Check Not Performed
vPC role : none established
Number of vPCs configured : 0
Peer Gateway : Enabled
Dual-active excluded VLANs : -
Graceful Consistency Check : Disabled (due to peer configuration)
Auto-recovery status : Disabled
Delay-restore status : Timer is off.(timeout = 30s)
Delay-restore SVI status : Timer is off.(timeout = 10s)
Operational Layer3 Peer-router : Disabled
Virtual-peerlink mode : Disabled
vPC Peer-link status

Any suggestions?

peer-keepalive destination 10.1.1.2 source 10.1.1.1 vrf heartbeat <<- this need both side

read the guide lines of vpc keepalive and vpc peer-link
We recommend that you associate the vPC peer-keepalive link to a separate VRF mapped to a Layer 3 interface in each vPC peer device. If you do not configure a separate VRF, the system uses the management VRF and management ports by default. Do not use the vPC Peer-Link itself to send and receive vPC peer-keepalive messages.
example of vPC can be find below my Blog :
