You can assign an interface to only one uplink-state group. Configure each
interface assigned to an uplink-state group as either an upstream or downstream
interface, but not both.
You can assign individual member ports of a port channel to the group. An uplink-
state group can contain either the member ports of a port channel or the port
channel itself, but not both.
