4 Configuration
By default, the Management VLAN is disabled. You can select any existing VLAN as the management VLAN
when this function is enabled. There can only be one management VLAN at a time.
VLAN > Voice VLAN > Voice VLAN Global 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. If a VoIP packet comes with a VLAN tag, the Voice VLAN function won't replace
the original VLAN tag.
Voice VLAN: 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 (1-120): 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.

Voice VLAN OUI Settings: This allows the user to configure the user-defined voice traffic's OUI. An
Organizationally Unique Identifier (OUI) is the first three bytes of the MAC address. This identifier uniquely
identifies a vendor, manufacturer, or other organization.
There are some pre-defined OUIs and when the user configures personal OUI, these pre-defined OUIs must
be avoided. Below are the pre-defined voice traffic's OUI:
