This field is enabled only for queues in WRR queue mode. If a queue is set to 0 weight, the queue is not operational and is effectively closed. Each queue has a weight range, queues 0-3 have the range 0-15 When mixing Strict and WRR mode, Strict mode should be configured at higher class.(Class 3 and Class 2) Weight Assigns the specific WRR value to the Queue. The weight value range is 0-15. 2. Select the Class IDs in the Mechanism field. 3. Click . The QoS Scheduling Mechanism is configured, and the device is updated. 125
