Voice VLAN

A voice VLAN is assigned to voice data flows. You can create a voice VLAN and add the interface connected to a voice device to the voice VLAN. Then voice data flows can be transmitted in the voice VLAN.

By configuring a voice VLAN, you can set quality of service (QoS) parameters for voice data flows to increase the priority of the voice service and improve the quality of calls.

• Voice VLAN
  You can set parameters of a voice VLAN.
• 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.
