3.1 Introduction to Voice VLAN
Voice VLANs are configured specially for voice traffic. By adding the ports that connect
voice devices to voice VLANs, you can configure quality of service (QOS for short)
attributes for the voice traffic, increasing transmission priority and ensuring voice quality.
A device determines whether a received packet is a voice packet by checking its source
MAC address. Packets containing source MAC addresses that comply with the voice
device Organizationally Unique Identifier (OUI for short) addresses are regarded as
voice traffic, and are forwarded in the voice VLANs.
You can configure the OUI addresses in advance or use the default OUI addresses,
which are listed as follows.
