Voice VLAN
Voice VLAN Global Settings
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.
To view the following window, click L2 Features > VLAN > Voice VLAN > Voice VLAN Global Settings, as

Aging Time (1-65535)
The aging time to set, the range is 1 – 65535 minutes. The default value is 720
minutes. The aging time is used to remove a port from voice VLAN if the port is an
automatic VLAN member. When the last voice device stops sending traffic and the
MAC address of this voice device is aged 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
