Defining OUIs
The
OUI Setting 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.
