two equipments may not go through. The solution will be letting the two equipments

positively send data packet to the switch (such as ping), to let the switch learn their

source MAC, then the two equipments will be able to communicate freely within the

dynamic VLAN.

Voice VLAN

2.18.1

Introduction to Voice VLAN

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.
