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.
