VOICE VLAN
Using Voice VLAN the switch is able to distinguish whether data is voice data or not according to the
source MAC fields of the ingress packets. If the source MAC address conforms to the voice device’s
OUI (Organizationally Unique Identifier) address, the packets will be regarded as voice data flow and
the port which has received the voice data flow will automatically join the voice VLAN. Thus, the
voice-VLAN-tagged voice traffic of voice devices connected to this port can be transmitted and enjoys
higher transmission priority. You can preset OUI address or use the default OUI address as the criteria.
An Organizationally Unique Identifier (OUI) is a 24-bit number that uniquely identifies a vendor,
manufacturer, or other organization globally or worldwide. This device supports OUI mask. You can
adjust MAC address’ matching depth by setting different masks.
