8.1 Overview
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.
VLAN-based QoS policies are also known as VLAN policies for short. VLAN policies
can facilitate the application and management of QoS policies on the switch.
VLAN policies are not effective on dynamic VLANs. VLAN policies will not be applied to
dynamic VLANs. For example, the device may create VLANs dynamically when GVRP
protocol is running. In this case, the corresponding VLAN policies are not effective on
dynamic VLANs.
Note:
For S5510 series Ethernet switches, if you apply traffic policing configured in a QoS
policy to a VLAN containing any of the first 12 ports and any of the last 16 ports on a
switch at the same time, the actual traffic limit may be twice the configured traffic limit.
8.2 Applying VLAN Policy
8.2.1 Configuration Prerequisites
The VLAN policy to be applied is defined. Refer to
policy defining.
VLANs where the VLAN policy is to be applied are determined.
