Defining a Policy A policy associates a class with a traffic behavior. Each traffic behavior is comprised
of a group of QoS actions. A device executes these QoS actions in the order they
are defined.
Follow these steps to associate a traffic behavior with a class:
n
In a QoS policy with multiple class-to-traffic-behavior associations, if the action of
creating an outer VLAN tag, the action of setting customer network VLAN ID, or
the action of setting service provider network VLAN ID is configured in a traffic
behavior, we recommend you not to configure any other action in this traffic
behavior. Otherwise, the QoS policy may not function as expected after it is
applied.
Applying a Policy Configuration procedure
Follow these steps to apply a policy on a port:
Note that, when you apply a policy by using the qos apply policy command,
whether or not the inbound / outbound keyword can take effect depends on the
actions defined in the traffic behavior, as described in Table 70.
