Use the qos wfq command to enable weighted fair queuing (WFQ) on a port or port group.  

Use the undo qos wfq command to restore the default.  

By default, the switch adopts the SP queue-scheduling algorithm. 

Related commands: display qos wrr interface.

queue-id: ID of the queue, in the range of 0 to 7. 

weight  schedule-value: Specifies the scheduling weight of a queue. The range for the scheduling 

weight depends on the LPU type of your S7900E series switch: 

z 

For EA LPUs, the scheduling weight of each queue is 1, that is, all queues share the allocable 

bandwidth (allocable bandwidth = total bandwidth – the sum of the minimum guaranteed bandwidth 

for each queue). 

z 

For non-EA LPUs, the scheduling weight ranges from 0 to 15, and each queue is allocated with part 

of the allocable bandwidth based on its scheduling weight.  

Use the qos wfq command to enable weighted fair queuing (WFQ) on a port or port group and 

configure a scheduling weight for the specified queue.  

Use the undo qos wfq command to restore the default. 

On a WFQ-enable port/port group, the scheduling weight of a queue is 1 by default.  

Related commands: display qos wfq interface, qos bandwidth queue. 

# Enable WFQ on GigabitEthernet 2/0/1 on a non-EA LPU and assign weight values 1, 2, 4, 6, 8, 10, 12, 

and 14 to queues 0 through 7.
