Modifying OUI The Voice VLAN OUI Modify Page allows network administrators to add Definitions new OUIs or to remove previously defined OUIs from the Voice VLAN. The
OUI is the first half (three most significant bytes) of the MAC address and is manufacturer specific, while the last three bytes contain a unique station ID. The packet priority derives from the source/destination MAC prefix. The packet gets higher priority when there is a match with the OUI list. Using the OUI, network managers can add a 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.
Monitor users have no access to this page.
