QoS polices support the following application modes:
Port-based application: QoS policies are effective for inbound packets on a
■
port.
VLAN-based application: QoS policies are effective for inbound traffic on a
■
VLAN.
A QoS policy is not effective on dynamic VLANs, for example, VLANs created by
GVRP.
The QoS policy to be applied is defined. Refer to "Configuring a QoS Policy" on
■
page 870 for policy defining.
VLANs where the QoS policy is to be applied are determined.
