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.

Click Apply to implement changes made.

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:

OUI Vendor Mnemonic Name

00:E0:BB 3Com 3com

00:03:6B Cisco cisco

00:E0:75 Veritel veritel

00:D0:1E Pingtel pingtel

00:01:E3 Siemens siemens

00:60:B9 NEC/ Philips nec&philips

00:0F:E2 Huawei-3COM huawei&3com

00:09:6E Avaya avaya

Default OUI: Pre-defined OUI values, including brand names of 3COM, Cisco, Veritel, Pingtel, Siemens,

NEC/Philips, Huawei3COM, and Avaya.

User defined OUI: You can manually create a Telephony OUI with a description. The maximum number of

user defined OUIs is 10. It will occupy one ACL rule when selecting a user defined OUI by default, and to

configure one user-defined OUI will take extra one ACL rule. System will auto generate an ACL profile

(Profile ID: 51) for all the Voice VLAN rules.

Select the OUI and press Add to the lower table to complete the Auto Voice VLAN setting.

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.
