inbound: Inbound direction.

outbound: Outbound direction.

policy-name: Policy name, a string of characters in the range 1 to 31.

dynamic: If this argument is applied when CBQ is applied on an interface, the 
CBQ bandwidth will be dynamically changed with the change of the interface 
bandwidth.

Use the qos apply policy command to apply associated policy to the interface.

Use the undo qos apply policy command to delete the associated policy from 
the interface.

To successfully apply the policy to the interface, you must make sure that the sum 
of bandwidth specified for the AF and EF classes in the policy is smaller than the 
available bandwidth of the interface. You can modify the available bandwidth of 
the current interface. If the sum of their bandwidth still exceeds that modified 
value, the policy will be deleted.

For a policy to be applied in the inbound direction, it cannot contain classes 
associated with traffic behaviors specified using queue af, queue ef, queue 
wfq, or gts.

Applying the policy on interface following these rules:

■

The VT interface referenced by common physical port and MP can apply the 
policy configured with various features, including remark, car, gts, queue af, 
queue ef, queue wfq, wred, etc.

■

The policy configured with TS (e.g. gts) and queue (e.g. queue ef, queue af, 
queue wfq) features cannot be applied on the inbound interface as the input 
direction policy.

■

Only the outbound direction policy configured with queue (e.g. queue ef, 
queue af, queue wfq) features can be applied on ATM PVC.

■

The subinterface does not support queue (e.g. queue ef, queue af, queue 
wfq) features but support TS (e.g. gts) and TP (e.g. car). Therefore, the policy 
configured with TS and TP can be applied on the sub-interface.
