3.Queue control

When there is a backlog on the output queue, packets remaining on the queue are transmitted or discarded depending on priority. The QoS discard mode command (qos-discard-mode) sets queue size and enables queuing by priority class.

For the configuration definition flow qos, please refer to Subsection 1.1.7 "flow qos". The configuration definitions qos-ip-list, qos-list-group, and qos-ip are described below.

The QoS IP list (qos-ip-list) command generates lists defining flow detection conditions and the various types of flow control active in flow detection. The QoS IP list group (qos-ip-list-group) command assigns a decision order to lists, allowing
