CBQ configuration example

Network requirements
As shown in Figure
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 of AF1 1 and AF21 and set a minimum guaranteed bandwidth percentage of 5% for the
traffic.
Perform EF for traffic with the DSCP value of EF and set the maximum bandwidth percentage for the

traffic to 30%.
Before performing the configuration, ensure the following:
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.

in each traffic behavior.
