The set vlans voice-vlan mac-address mask command configures the OUI address for the voice VLAN.
set vlans voice-vlan mac-address <mac-address> mask <oui-mask>
Specifies the OUI address for voice VLAN.
The value is in H:H:H:H:H:H format. An H contains 2 hexadecimal numbers. The address cannot be all 0s, multicast address, or broadcast address.
Specifies the mask for the OUI address.
OUI refers to the first 24 bits (binary) of the MAC address that can be used to represent a MAC address segment, which is a globally unique identifier assigned by the IEEE to different device vendors, each device vendor then allocates 24 bit to form a 48-bit MAC address.
In voice VLAN, the OUI is not necessarily 24 bits long which depends on the mask value. The OUI is the result of the AND operation between the MAC address and the mask in the set vlans voice-vlan mac-address mask command.
The switch identifies packets as voice data when the source MAC address matches the system pre-configured Organizationally Unique Identifier (OUI).
The system supports a maximum of 10 OUIs, including the default 7 OUIs. In PICOS 2.11.4 and the later version , there is no default OUI, the user is allowed to configure a maximum of 10 OUIs.
