• The voice-VLAN function is globally enabled.
• The voice-VLAN function is enabled on the port.

Configure an OUI Address

Organizationally Unique Identifiers (OUIs) are used to identify voice packets that are sent by voice devices of manufacturers. After a port that works in voice-VLAN automatic mode receives an Untag packet, it takes out the MAC address of the packet and performs the AND operation with the OUI mask. If the obtained address range is the same as the OUI address, it indicates that matching the OUI address succeeds, and the packet is recognized as a voice packet.
