In Qumran devices, every physical port has default eight priority queues and subinterface has default 4 priority queues when service-queue profile1 is active and 8 queues (distributed between 4 priorities) when service-queue profile2 is active. Physical port queues are created during initialization while the subinterface queues will be created/deleted when encap is set/unset respectively on subinterface. Whenever QoS feature is enabled, all priority queues of the physical ports/subinterafce will be configured with certain default egress queuing parameters.

In order to customize the treatment on the priority queues, queuing policy-map infrastructure need to be used.
