CBQ Configuration Example
Network requirements
As shown in Figure 40 , traffic travels from Router C to Router D through Device A and Device D. Traffic
from Router C is classified into three classes based on DSCP. Configure a QoS policy to:
• Perform AF for traffic with the DSCP value being AF11 or 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 configuration, make sure that:
• Router C and Router D are reachable to each other across Device A and Device B.
• The DSCP fields have been set for the traffic before the traffic enters Router A.
