Voice VLAN configuration

Overview

A voice VLAN is configured for voice traffic. After assigning the ports that connect to voice devices to a
voice VLAN, the system automatically configures quality of service (QoS) parameters for voice traffic, to
improve the transmission priority of voice traffic and ensure voice quality.
NOTE:
Common voice devices include IP phones and integrated access devices (IADs). Only IP phones are
used in the voice VLAN configuration examples in this document.

OUI addresses

A device determines whether a received packet is a voice packet by evaluating its source MAC address.
A packet whose source MAC address complies with the Organizationally Unique Identifier (OUI) address
of the voice device is regarded as voice traffic.
You can configure the OUI addresses of a device in advance or use the default OUI addresses.

NOTE:

In general, as the first 24 bits of a MAC address (in binary format), an OUI address is a globally unique
identifier that IEEE assigns to a vendor. In this document, however, OUI addresses are addresses that the system
uses to determine whether a received packet is a voice packet. They are the results of the AND operation of the
arguments

You can remove the default OUI address of a device manually and then add new ones manually.

Voice VLAN assignment modes

A port can be assigned to a voice VLAN in one of the following modes:
OUI address
0001-e300-0000
0003-6b00-0000
0004-0d00-0000
