z 

Adopts WRR for queue scheduling, setting the weights of the output queues to 2, 2, 3, 

3, 4, 4, 5, and 5 (in the order queue 0 through queue 7). 

z 

Verify the configuration.  

Configuration procedure: 

<Sysname> system-view 

[Sysname] queue-scheduler wrr 2 2 3 3 4 4 5 5 

[Sysname] display queue-scheduler 

 Queue scheduling mode: weighted round robin 

 weight of queue 0: 2 

 weight of queue 1: 2 

 weight of queue 2: 3 

 weight of queue 3: 3 

 weight of queue 4: 4 

 weight of queue 5: 4 

 weight of queue 6: 5 

 weight of queue 7: 5  

Refer to section 

 for information about WRED.  

z 

The indexes of queues to be dropped at random, the queue length that starts the drop 

action, and the drop probability have been determined. 

z 

The ports that need this configuration have been determined. 

Follow these steps to configure WRED: 

Enter system view 

— 

Enter Ethernet port view

Required 

By default, WRED is not 
configured.  

 

Configure WRED for queue 2 of Ethernet 1/0/1 to drop the packets in queue 2 randomly 

when the number of packets in queue 2 exceeds 64, setting the dropping probability being 

20%.
