QOS configuration of the S9300 port of the Huawei S9300 switch the queue scheduling mechanism. Each physical port has eight sending queues. The queue 7 has the highest priority, and the queue 0 has the lowest priority. The sending port supports PQ, WRR, and DRR scheduling methods, and hybrid scheduling of PQ + WRR and PQ + DRR. When www.2cto.com is used for hybrid scheduling, packets in the PQ queue are fir

queues, the DSCP-to-CoS Map and Cos-to-Queue Map ing tables configured on the vswitch are used to convert the DSCP values of packets into output Queue numbers, in order to determine the output queue to which the message should be sent. Scheduling The last step of the QoS process during Scheduling. After the packets are sent to different output queues on the port, the switch uses WRR or SP Rotation Algorithm to send the packets in the eight queues. Yo
