Voice VLAN
Voice VLAN Global
Voice VLAN is a VLAN used to carry voice traffic from IP phone. Because the sound quality of an IP
phone call will be deteriorated if the data is unevenly sent, the quality of service (QoS) for voice traffic
shall be configured to ensure the transmission priority of voice packet is higher than normal traffic.
The switches determine whether a received packet is a voice packet by checking its source MAC
address. If the source MAC addresses of packets comply with the organizationally unique identifier (OUI)
addresses configured by the system, the packets are determined as voice packets and transmitted in
voice VLAN.

out, the voice VLAN aging timer will be started. The port will be
removed from the voice VLAN after expiration of voice VLAN aging
timer. If the voice traffic resumes during the aging time, the aging
timer will be reset and stop.
