Hi,
I have two Cisco nexus 7K connected with Cisco 3750 switch as Trunk port. A port channel vPC is configured on both switches
working fine on Nexus 1 but vPC is down at Nexus 2 and port status is suspended. The configuration consistency is formed and working fine.
What could be the issue?

Could you please share the below outputs from both the Nexus devices in separate files.:
- show version
- show vpc
- show vpc consistency-parameters int port-ch <po#>
- show run all
Most common reason for the suspended state is either failing of consistency parameters or MTU mismatch on both Nexus Devices.
Regards

Hello Rizwan
Thanks for the logs. i see that the po102 is in down state. Could you please share the below output from the problematic Nexus:
sh lacp internal event-history interface e1/10
Was the port-channel UP before you configured vpc or vpc peer-link?
Also, could you please share the show run all from both the Nexus devices
Thanks,
Vinit

Hello,
Problem seems to be the speed negotiation.
Try to set them manually on both sides to check.
speed 10000
