Usage 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. 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.
Example
DellEMC(conf-uplink-state-group-16)# upstream gigabitethernet 1/10-15
