Defining A Policy; Applying The Qos Policy - HP 4800G Series Configuration Manual

Defining a Policy

In a policy, you can define multiple class-behavior associations. A behavior is performed for the
associated class of packets. In this way, various QoS features can be implemented.
Follow these steps to associate a class with a behavior in a policy:
To do...
Enter system view
Create a policy and enter policy
view
Associate a class with a
behavior in the policy
If an ACL is referenced by a QoS policy for defining traffic match criteria, packets matching the ACL
are organized as a class and the behavior defined in the QoS policy applies to the class regardless
of whether the match mode of the if-match clause is deny or permit.
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.
The do1q-tag-manipulation keyword is applicable to only many-to-one VLAN mapping
configuration. For information about many-to-one VLAN mapping, refer to VLAN Mapping
Configuration in the Access Volume.

Applying the QoS Policy

You can apply a QoS policy to different occasions:
Applied to an interface, the policy takes effect on the traffic sent or received on the interface.
Applied to a user profile, the policy takes effect on the traffic sent or received by the online users of
the user profile.
Applied to a VLAN, the policy takes effect on the traffic sent or received on all ports in the VLAN.
Applied globally, the policy takes effect on the traffic sent or received on all ports.
Use the command...

association is defined for VLAN
