Voice VLAN is specially configured for the user voice data traffic. By setting a Voice
VLAN and adding the ports of the connected voice equipments to the Voice VLAN, the
user will be able to configure QoS (Quality of service) service for voice data, and improve
the voice data traffic transmission priority to ensure the calling quality
The switch can judge if the data traffic is the voice data traffic from specified
equipment according to the source MAC address field of the data packet entering the port.
The packet with the source MAC address complying with the system defined voice
equipment OUI (Organizationally Unique Identifier) will be considered the voice data
traffic and transmitted to the Voice VLAN.
The configuration is based on MAC address, acquiring a mechanism in which
every voice equipment transmitting information through the network has got its unique
MAC address. VLAN will trace the address belongs to specified MAC. By This means,
VLAN allows the voice equipment always belong to Voice VLAN when relocated
physically. The greatest advantage of the VLAN is the equipment can be automatically
placed into Voice VLAN according to its voice traffic which will be transmitted at specified
priority. Meanwhile, when voice equipment is physically relocated, it still belongs to the
Voice VLAN without any further configuration modification, which is because it is based
on voice equipment other than switch port.
