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.

22.6 Voice VLAN Configuration
22.6.1
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. 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.
Notice: Voice VLAN needs to associate with Hybrid attribute of the ports to work, so the
