# Create QoS policy QUEUE, and associate the behaviors with the classes to meet the
following requirements: guarantee 10% of the bandwidth for traffic with an EXP value of 1,
guarantee 20% of the bandwidth for traffic with an EXP value of 2, guarantee 30% of the
bandwidth for traffic with an EXP value of 3, and guarantee a low delay and 40% of the
bandwidth for traffic with an EXP value of 4.

After the configuration, when congestion occurs in VPN 1, the bandwidth proportion between
flows with the DSCP value being af11, af21, af31, and ef is 1:2:3:4, and the delay for the flow
with the DSCP value being ef is smaller than the other traffic flows.
