Configuration Guidelines
 ■ Before configuring voice VLAN, you need to create a 802.1Q VLAN for voice traffic. For 
details about 802.1Q VLAN Configuration, please refer to Configuring 802.1Q VLAN.
 ■ VLAN 1 is a default VLAN and cannot be configured as the voice VLAN.
 ■ Only one VLAN can be set as the voice VLAN on the switch.
4.1  Using the GUI
4.1.1  Configuring OUI Addresses
The OUI address is assigned as a unique identifier by IEEE (Institute of Electrical and 
Electronics Engineers) to a device vendor. It is used by the switch to determine whether a 
packet is a voice packet.
If the OUI address of your voice device is not in the OUI table, you need to add the OUI 
address to the table.
Choose the menu QoS > Voice VLAN > OUI Config to load the following page.
