9.3 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 packets comply with the OUI addresses configured by the
system, the packets are determined as voice packets 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.
