华为S9300 交换机QOS配置（Huawei S9300 switch QOS configuration） Huawei S9300 switch QOS configuration The queue scheduling mechanism for the port of S9300 Each physical port has 8 send queues, queue 7 has the highest priority, and the queue 0 priority is the lowest. The sending port supports queue scheduling with PQ, WRR, and DRR, and supports mixed scheduling of PQ + WRR and PQ + DRR. When mixing scheduling, the PQ queue is dispatched first, and the highest priority queue is first dispatched when PQ dispatching, and the post-dispatch priority is lower. The WRR or DRR queues are scheduled after the PQ queue is scheduled. For WRR and DRR queues, the queue guarantees the bandwidth first and then the WRR and DRR are dispatched according to the weight. How to support port speed limit The speed limit for the incoming port is configured with QOS CAR under the port, and in addition the flow strategy can be configured to configure the ACL rule convection in the classifier to speed the speed limit. QOS CAR does not support the port speed limit of the direction, but the port speed limit and flow speed of the outlet can be limited by the flow strategy or port flow in the direction of the port. S9300 supports access control, redirection, rate limit, port image Support for direction and incoming access control. The flow redirection of support is not supported in the direction of redirection. The speed limit for direction and orientation is supported. Supports the orientation and direction of the mirror image. How to do flow configuration Flow shaping is to control the rate of the output message, so that the message can be sent out at a uniform rate. The speed limit of the port can be realized through the flow shaping function. Flow shaping can be done on ports or priority queues. Enter the port view, and then the flow of the flow: [Quidway] interface gigabitethernet 3/0/1 [Quidway - gigabitethernet3/0/1] qos lr cir 100,000 [quidway-gigabitethernet3/0/1] qos queue 0 shaping cir 50000 pir
