This read-create DisplayString names or points to a Queue Profile defining how this interface's egress queues, their scheduling and weights, should be configured. An admin uses this to apply a standardized queue-scheduling configuration, such as strict priority plus weighted round robin, to an interface without manually configuring every queue parameter on that port. For example, an admin wanting all uplink ports to use the same 8-queue scheduling scheme would point this field on each uplink to the same predefined queue profile name.
