57.11 Voice VLAN
Voice VLAN is a VLAN that is specifically allocated for voice traffic. It ensures that the sound quality of an
IP phone is preserved from deteriorating when the data traffic on the Switch ports is high. It groups the
voice traffic with defined priority into an assigned VLAN which enables the separation of voice and
data traffic coming onto the Switch port.
The Switch can determine whether a received packet is
• an untagged voice packet when the incoming port is a fixed port for voice VLAN.
• a tagged voice packet when the incoming port and VLAN tag belongs to a voice VLAN.
It then checks the source packet’s MAC address against an OUI list. If a match is found, the packet is
considered as a voice packet.
You can set priority level to the Voice VLAN and add MAC address of IP phones from specific
manufacturers by using its ID from the Organizationally Unique Identifiers (OUI).
Click SWITCHING > VLAN > Voice VLAN Setup to display the configuration screen as shown.
