queues and scheduling algorithms you set. On this switch, the priority levels are labeled as TC0, TC1, TC2, TC3, TC4, TC5,TC6 and TC7. Syntax qos queue weight { tc-id } { weight-value } Parameter tc-id -- The ID of the TC queue, ranging from 0 to 7. weight-value -- Configure the weight value of the specified TC queue. When the schedule mode is specified as WRR, the weight value ranges from 1 to 127. The 8 queues will take up the bandwidth according to their ratio. The default values of TC0, TC1, TC2, TC3, TC4, TC5,TC6 and TC7 are 1, 2, 4, 8, 16, 32, 64 and 127 respectively. When the schedule mode is specified as SP+WRR, the weight value ranges from 0 to 127. TC7 and the queue with its weight value set as 0 are in the SP group; other queues, with none-zero weight value, belong to the WRR group. In this SP+WRR scheduling mode, the queues in the SP group is scheduled preferentially (TC6>TC5>TC4>TC3>TC2>TC1>TC0 in strict priority). When there is no packets to be sent in the SP group, the queues in the WRR group will be scheduled according to the weight value of each queue. The default weight values of TC0, TC1, TC2, TC3, TC4, TC5 and TC6 are 1, 2, 4, 8, 16, 32 and 64 respectively, while the value of TC7 is 0 and non-configurable. Command Mode Global Configuration Mode Privilege Requirement Only Admin, Operator and Power User level users have access to these commands. Example Specify the Schedule Mode as Weight Round Robin Mode, with the weight values of TC0, TC1, TC2 and TC3 as 4, 7, 15 and 24: T1700G-28TQ(config)# qos queue mode wrr T1700G-28TQ(config)# qos queue weight 0 4 T1700G-28TQ(config)# qos queue weight 1 7 T1700G-28TQ(config)# qos queue weight 2 15 T1700G-28TQ(config)# qos queue weight 3 24 167
