VPC Trunks - Limit VLANs at Port Channel Interface AND Ethernet Port?

[CiscoMedMed]

When creating a port channel on Nexus (part of a VPC pair), do you restrict VLANs
at both the Ethernet interface *and* the port channel interface? Or just one or the other? 
Thank you.

It all depends on order of operation.

Technically once you assign the interface to port-channel and Later configure port-channel configuration it will be sufficient.

But worth cross-checking is the interface got the right config what you configured on port-channel is the same on interface too.
