CBQ configuration example
Network requirements
As shown in Figure 17, configure a QoS policy to meet the following requirements:
• Traffic from Router C is classified into three classes based on DSCP values. Perform AF for traffic with
the DSCP values being AF11 and AF21, and set a minimum guaranteed bandwidth percentage of
5% for the traffic.
• Perform EF for traffic with the DSCP value being EF and set the maximum bandwidth percentage for
the traffic to 30%.
Before performing the configuration, make sure:
• The route from Router C to Router D through Router A and Router B is reachable.
• The DSCP fields have been set for the traffic before the traffic enters Router A.
