Voice VLAN OUI

A switch checks whether an incoming flow is a voice data flow according to the source MAC address of the data flow. If the source MAC address of the data flow matches the organizationally unique identifier (OUI) address set in the system, the switch considers the data flow as a voice data flow. When an interface receives a voice data flow, the interface is added to the voice VLAN automatically. The voice flows with the voice VLAN tag sent from the voice device connected to the interface can be forwarded by the interface.

Context

You can set an OUI address. The OUI is the first 24 bits of a MAC address. The institute of Electrical and Electronics Engineers (IEEE) assigns an OUI to each vendor and you can identify the vendor of a device according to the OUI. You can set the mask of the OUI on the switch to adjust the length of the MAC address that the switch matches with the OUI.
