Defining a policy

You associate a behavior with a class in a QoS policy to perform the actions defined in the behavior for
the class of packets.

Configuration restrictions and guidelines

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 action in the rule is deny or permit.
• In a QoS policy with multiple class-to-traffic-behavior associations, if the action of creating an outer
VLAN tag, setting customer network VLAN ID, or setting service provider network VLAN ID is
configured in a traffic behavior, do not configure any other action in this traffic behavior; otherwise,
the QoS policy may not function as expected after it is applied. For more information about the
action of setting customer network VLAN ID or service provider network VLAN ID, see Layer
2—LAN Switching Configuration Guide.

Configuration procedure

To associate a class with a behavior in a policy:
Step
1. Enter system view.
2. Create a policy and enter
policy view.
3. Associate a class with a
behavior in the policy.
The dot1q-tag-manipulation keyword is only for VLAN mapping purposes. For more information about
VLAN mapping, see Layer 2—LAN Switching Configuration Guide.

Applying the QoS policy

You can apply a QoS policy to the following occasions:
An interface—The policy takes effect on the traffic sent or received on the interface.
•
A user profile—The policy takes effect on the traffic sent or received by the online users of the user
•
profile.
A VLAN—The policy takes effect on the traffic sent or received on all ports in the VLAN.
•
• Globally—The policy takes effect on the traffic sent or received on all ports.
The QoS policies applied to ports, to VLANs, and globally are in the descending priority order. If the
system finds a matching QoS policy for the incoming/outgoing traffic, the system stops matching the
traffic against QoS policies.
You can modify classes, behaviors, and class-behavior associations in a QoS policy applied to an
interface, VLAN, or inactive user profile, or globally. If a class references an ACL for traffic classification,
you can delete or modify the ACL (such as add rules to, delete rules from, and modify rules of the ACL).
