FAQ-How Do I Enable Packets with a Specific DSCP to Enter High-Priority Queues

Publication Date:  2015-05-06 Views:  366 Downloads:  0
Issue Description
How Do I Enable Packets with a Specific DSCP to Enter High-Priority Queues?
Solution

Use traffic classifiers to enable packets with high differentiated services code point (DSCP) values to enter expedited forwarding (EF) queues, and to ensure that the packets are transmitted preferentially. For example, to enable packets with a DSCP of 22 to enter EF queues, configure the following:

<Huawei> system-view
[Huawei] traffic classifier c1
[Huawei-classifier-c1] if-match dscp 22
[Huawei-classifier-c1] quit
[Huawei] traffic behavior b1
[Huawei-behavior-b1] queue ef bandwidth 100 cbs 2500
[Huawei-behavior-b1] quit
[Huawei] traffic policy p1
[Huawei-trafficpolicy-p1] classifier c1 behavior b1
