Aging Time: Enter a period of time (in hours) to remove a port from the 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 start. The port will be removed from the voice VLAN
after the expiration of the voice VLAN aging timer. Selectable range is from 1 to 120 hours, and default is 1
hour.
From Port / To Port: A consecutive group of ports may be configured starting with the selected port.
Auto Detection: Switch will add ports to the voice VLAN automatically if it detects the device OUI matches
the Telephony OUI configured in the Voice VLAN OUI Setting page. Use the drop-down menu to enable or
disable the OUI auto detection function. The default is Disabled
Click Apply to implement changes made.
Note: Voice VLAN has higher priority than any
other features (including QoS). Therefore the
voice traffic will be operated according to the
Voice VLAN setting and not impacted by the QoS
feature.
Note: It is recommended setting the highest
priority for Voice VLAN to guarantee the quality of
VoIP traffic.
