Configuring Queue-based Congestion Management

Procedure

1. Run system-view

   The system view is displayed.

2. Run qos queue-profile queue-profile-name

   A queue profile is created and the queue profile view is displayed.

3. Run the following commands as required.

   • On a WAN interface, run schedule { pq start-queue-index [ to end-queue-index ] | wfq start-queue-index [ to end-queue-index ] }^*

     A scheduling mode is configured for each queue on the WAN interface.

   • On a layer 2 VE interface, run schedule { pq start-queue-index [ to end-queue-index ] | wfq start-queue-index [ to end-queue-index ] }^*

     A scheduling mode is configured for each queue on the layer 2 VE interface.

   • On a LAN interface, run schedule { pq start-queue-index [ to end-queue-index ] | drr start-queue-index [ to end-queue-index ] | wrr start-queue-index [ to end-queue-index ] }^*

     A scheduling mode is configured for each queue on the LAN interface.

     By default, all the queues on LAN-side interfaces (except Layer 2 VE interfaces) use WRR, and all the queues on WAN-side interfaces and Layer 2 VE interfaces use WFQ.

4. (Optional) Run queue { start-queue-index [ to end-queue-index ] } &<1-10> length { bytes bytes-value | packets packets-value }^*

   The length of each queue is set on the interface.

5. (Optional) Run queue { start-queue-index [ to end-queue-index ] } &<1-10> weight weight-value

   The weight of each queue is set on the interface.

   By default, the weight of a queue is 10.

6. Run quit

   Exit from the queue profile view.

7. Run interface interface-type interface-number[.subinterface-number ]

   The interface view or sub-interface view is displayed.

8. Run qos queue-profile queue-profile-name

   The queue profile is applied to the interface or sub-interface.
