In a LAN, voice devices, such as IP phones, VoIP endpoints, and voice systems are
placed into the same VLAN. This VLAN is referred as the voice VLAN. The voice
VLAN is used when traffic from VoIP equipment or phones is assigned to a
specific VLAN. The switch can automatically detect and add port members to the
voice VLAN, and assign the configured quality of service (QoS) to packets from
the voice VLAN.
Dynamic Voice VLAN Modes
The switch supports two dynamic voice VLAN modes. They are Telephony OUI
(Organization Unique Identifier) mode and Auto Voice VLAN mode. The two
modes affect how voice VLAN and/or voice VLAN port memberships are
configured. The two modes are mutually exclusive to each other.
• Telephony OUI—In Telephony OUI mode, the voice VLAN must be a
manually configured VLAN, and cannot be the default VLAN.
When the switch is in Telephony OUI mode and a port is manually
configured as a candidate to join the voice VLAN, the switch dynamically
adds the port to the voice VLAN if it receives a packet with a source MAC
address matching to one of the configured telephony OUIs. An OUI is the
first three bytes of an Ethernet MAC address. For more information about
Telephony OUI, see the
• Auto Voice VLAN—In Auto Voice VLAN mode, the voice VLAN can be
either the default voice VLAN or manually configured.
