Configuring an OUI for a Voice VLAN

Configuring an OUI for a Voice VLAN


An Organizationally Unique Identifier (OUI) is the first 24 bits of a MAC address, and is a unique identifier assigned to a device vendor.

An OUI represents a MAC address segment that is obtained by performing the AND operation between a 48-bit MAC address and a mask. If the first 24 bits of the MAC address of a device are the same as an OUI, a voice VLAN-enabled port considers the device as a voice device and data from the device as voice data.


  1. Run system-view

    The system view is displayed.

  2. Run voice-vlan mac-address mac-address mask oui-mask [ description text ]

    An OUI is configured.

    When configuring an OUI for a voice VLAN, note the following:
    • The mac-address value cannot be all 0s or a multicast or broadcast address.

    • A device can be configured with a maximum of 16 OUIs. When the device is configured with 16 OUIs, subsequent configurations will not take effect.

    • When using the undo voice-vlan mac-address mac-address command to delete an OUI, specify the mac-address value in this command as the result of the AND operation by using the configured MAC address and mask.
