Defining OUIs
The Voice VLAN OUI page lists the Organizationally Unique Identifiers (OUIs) associated with the
Voice VLAN. The first three bytes of the MAC Address contain a manufacturer identifier. While the last
three bytes contain a unique station ID. Using the OUI, network managers can add specific
manufacturer’s MAC addresses to the OUI table. Once the OUIs are added, all traffic received on the
Voice VLAN ports from the specific IP phone with a listed OUI, is forwarded on the voice VLAN.
To open the Voice VLAN OUI page, click Switch Voice VLAN OUI in the tree view.
