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 on the MAC address and is manufacture 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 specific manufacture'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.

1 Click Device > QoS > VoIP Traffic Setting > OUI Modify. The Voice
