Change the OUI table for the voice VLAN
For the voice VLAN, the switch supports default Organizationally Unique Identifiers
(OUIs), which are associated with VoIP phones of specific manufacturers. All traffic
received on voice VLAN ports from VoIP phones with a listed OUI is forwarded on the
voice VLAN.
You can add, change, and remove OUIs, including the default OUIs. The maximum
number of OUI entries in the table is 15. The first 3 bytes of the MAC address contain
a manufacturer identifier, and the last 3 bytes contain a unique station ID. You must add
an OUI prefix in the format AA:BB:CC.
You can add a new OUI, change an existing OUI, and delete an OUI that you no longer
need.
To change the OUI table for the voice VLAN:

switch, or connected directly to the switch through an Ethernet cable.
