Voice Vlan - D-Link DGS-1100-16 Reference Manual

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.

Enter the aging time of surveillance VLAN. The range is
from 1 to 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 reset
and stop.
