12.3 Voice VLAN

Voice VLANs are configured specially for voice data stream. By configuring Voice VLANs and
adding the ports with voice devices attached to voice VLANs, you can perform QoS-related
configuration for voice data, ensuring the transmission priority of voice data stream and voice
quality.
OUI Address (Organizationally unique identifier address)

The switch can determine whether a received packet is a voice packet by checking its source MAC
address. If the source MAC address of a packet complies with the OUI addresses configured by
the system, the packet is determined as voice packet and transmitted in voice VLAN.
An OUI address is a unique identifier assigned by IEEE (Institute of Electrical and Electronics
Engineers) to a device vendor. It comprises the first 24 bits of a MAC address. You can recognize
which vendor a device belongs to according to the OUI address. The following table shows the
OUI addresses of several manufacturers. The following OUI addresses are preset of the switch by
default. The OUI Address entries below can be modified manually.
Port Voice VLAN Mode

A voice VLAN can operate in two modes: automatic mode and manual mode.
Automatic Mode: In this mode, the switch automatically adds a port which receives voice packets
to voice VLAN and determines the priority of the packets through learning the source MAC of the
UNTAG packets sent from IP phone when it is powered on. The aging time of voice VLAN can be
configured on the switch. If the switch does not receive any voice packet on the ingress port within
Select the bandwidth for receiving UL-Frame on the port. The
packet traffic exceeding the bandwidth will be discarded. Select
Disable to disable the UL-Frame control function for the port.
