R3303-HP 6600/HSR6600 Routers ACL and QoS Configuration Guide

• Perform AF for packets with DSCP AF11 or AF21, and set the minimum guaranteed bandwidth to

500 kbps for the packets.

• Perform EF for packets with DSCP EF, and set the maximum bandwidth to 2000 kbps for the

packets.

Configuration procedure

Before performing the configuration, make sure that:

• Router C and Router D can reach each other through Router A and Router B.

• The DSCP field of the traffic has been set before it enters Router A.

Configure Router A:

# Define three classes to match the IP packets with DSCP 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. Enable AF and set the minimum guaranteed bandwidth to 500 kbps in

each traffic behavior.

[RouterA] traffic behavior af11_behav

[RouterA-behavior-af11_behav] queue af bandwidth 500

[RouterA-behavior-af11_behav] quit

[RouterA] traffic behavior af21_behav

[RouterA-behavior-af21_behav] queue af bandwidth 500

[RouterA-behavior-af21_behav] quit

# Define a traffic behavior. Enable EF and set the maximum bandwidth to 2000 kbps in the traffic

behavior.

[RouterA] traffic behavior ef_behav

[RouterA-behavior-ef_behav] queue ef bandwidth 2000
