Description
Use the voice vlan mac-address command to add an OUI entry to the OUI list for the specified MAC

considered as a voice packet only when its source MAC address can match an entry in the OUI list.
Use the undo voice vlan mac-address command to remove an OUI entry from the OUI list.
By default, the OUI list contains the five pre-defined OUI addresses in
Table 1-2. You can modify them
with the voice vlan mac-address command.
