OUI Settings

The switch determines whether a received packet is a voice packet by checking its source MAC address. VoIP traffic has a preconfigured Organizationally Unique Identifiers (OUI) prefix in the source MAC address. You can manually add specific manufacturer’s MAC addresses and description to the OUI table. All traffic received on the Voice VLAN ports from the specific IP phone with a listed OUI is forwarded on the voice VLAN.

To configure the OUI settings, click the Edit button to re-configure the specific entry. Click the Delete button to remove the specific entry or click the Add button to create a new OUI entry.
