Configuration > Voice VLAN > Voice VLAN Settings
Voice VLAN is a feature that allows you to automatically place the voice traffic from IP phone to an assigned
VLAN to enhance the VoIP service. With a higher priority and individual VLAN, the quality and the security of
VoIP traffic are guaranteed. The Voice VLAN function will only insert the Voice VLAN tag to untagged
packets under corresponding ports. If a VoIP packet comes with a VLAN tag, the Voice VLAN function won't
replace the original VLAN tag.
Voice VLAN State: Select to enable or disable Voice VLAN. The default is Disabled. After you enabled
Voice VLAN, you can configure the Voice VLAN Global Settings.
VLAN ID: The ID of VLAN that you want to assign voice traffic to. You must first create a VLAN from the
802.1Q VLAN page before you can assign a dedicated Voice VLAN. The member port you configured in
802.1Q VLAN setting page will be the static member port of voice VLAN. To dynamically add ports into the
voice VLAN, please enable the Auto Detection function
Priority: The 802.1p priority levels of the traffic in the Voice VLAN.
Aging Time: Enter a period of time in hours 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. 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 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 and Refresh to refresh the voice vlan table.
