or—The device considers a packet belongs to a class as long as the packet matches one of the
criteria in the class.
A traffic behavior, identified by a name, defines a set of QoS actions for packets.
You can apply a QoS policy to a VLAN or a port.
VLAN Policy—Applies a QoS policy to a VLAN to regulate all traffic of the VLAN. QoS policies
cannot be applied to dynamic VLANs, such as VLANs generated by GVRP.
Port Policy—Applies a QoS policy to a port to regulate the inbound or outbound traffic of the
port. A QoS policy can be applied to multiple ports. Only one policy can be applied in one
direction (inbound or outbound) of a port.

Applying a policy to a port
Queue scheduling configuration procedure
Configuring queue scheduling on a port
to configure a QoS policy:
Add a class and specify the logical relationship
between the match criteria in the class.
Configure match criteria for the class.
Add a traffic behavior.
Use either approach.
Configure various actions for the traffic behavior.
Add a policy.
Associate the traffic behavior with the class in the
A class can be associated with only one traffic
behavior in a QoS policy. Associating a class
already associated with a traffic behavior will
overwrite the old association.
Configure the queue scheduling mode for a port.
