Configuration procedure

Configure Router A:

# Define three classes to match the IP packets with the DSCP values AF11, AF21, and EF, respectively.

<RouterA> system-view

[RouterA] traffic classifier af11_class

[RouterA-classifier-af11_class] if-match dscp af11

[RouterA-classifier-af11_class] quit

[RouterA]traffic classifier af21_class

[RouterA-classifier-af21_class] if-match dscp af21

[RouterA-classifier-af21_class] quit

[RouterA] traffic classifier ef_class

[RouterA-classifier-ef_class] if-match dscp ef

[RouterA-classifier-ef_class] quit

# Define two traffic behaviors, and enable AF and set a minimum guaranteed bandwidth percentage of

5% in each traffic behavior.

[RouterA] traffic behavior af11_behav

[RouterA-behavior-af11_behav] queue af bandwidth pct 5

[RouterA-behavior-af11_behav] quit

[RouterA] traffic behavior af21_behav

[RouterA-behavior-af21_behav] queue af bandwidth pct 5

[RouterA-behavior-af21_behav] quit

# Define a traffic behavior, and enable EF and set a maximum bandwidth percentage of 30% (both

bandwidth and delay are guaranteed for EF traffic) in the traffic behavior.

[RouterA] traffic behavior ef_behav

[RouterA-behavior-ef_behav] queue ef bandwidth pct 30

[RouterA-behavior-ef_behav] quit

# Define a QoS policy and associate the configured traffic behaviors with classes in the QoS policy.

[RouterA] qos policy dscp

[RouterA-qospolicy-dscp] classifier af11_class behavior af11_behav

[RouterA-qospolicy-dscp] classifier af21_class behavior af21_behav

[RouterA-qospolicy-dscp] classifier ef_class behavior ef_behav

[RouterA-qospolicy-dscp] quit
