Information
You can assign physical port or port-channel interfaces to an uplink-state group.
You can assign an interface to only one uplink-state group. You must configure
each interface assigned to an uplink-state group as either an upstream or
downstream interface, but not both.

state group can contain either the member ports of a port channel or the port
channel itself, but not both.
