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
as listed in Table
