Queue mode shall be set to control the sequence of outputting a packet to the
transmission queue in the interface. The queue mode includes the following five
catergories: output priority control, minimum band assurance, uniformity
assurance, minimum uniformity band assurance, and minimum band assurance
(kbps designation). The definition method defines a queue list to be set in the
transmission queue of the interface by using the QoS attribute (qos-queue-list)
and further sets a queue list to be used on each interface by using the QoS
interface information (qos-interface).

The queue control is a function that discards a packet to be stacked on the
transmission queue according to the queuing priority if the packet is stagnating
in the transmission queue. The function sets the pattern of queue length
permitting the queuing on each queuing priority by using the QoS discard mode
(qos-discard-mode).
