3. Apply a policy to the
interface or PVC.
qos apply policy policy-name
{ inbound | outbound }
On some cards, QoS policies can
be applied but cannot take effect
due to limited system resources. In
this case, you can adjust related
parameters (for example, reducing
the number of queues) according
to system prompt and then apply a
QoS policy again.

CBQ configuration example
Network requirements
As shown in Figure 28, configure a QoS policy to do the following:
• Classify traffic from Router C into three classes based on DSCP values.
• 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.
