Required
Specify the
dot1q-tag-manipulation
keyword
if the class-behavior association is
defined for VLAN mapping.
z 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.
z 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.
z The do1q-tag-manipulation keyword is applicable to only many-to-one VLAN mapping
configuration. For information about many-to-one VLAN mapping, see VLAN Mapping
Configuration in the Layer 2 - LAN Switching Configuration Guide.
Applying the QoS Policy
You can apply a QoS policy to different occasions:
z Applied to an interface, the policy takes effect on the traffic sent or received on the interface.
z Applied to a user profile, the policy takes effect on the traffic sent or received by the online users
of the user profile.
z Applied to a VLAN, the policy takes effect on the traffic sent or received on all ports in the VLAN.
z Applied globally, the policy takes effect on the traffic sent or received on all ports.
z Applied to the control plane, the policy takes effect on the traffic sent or received on the control
plane.
