GVRP:
The Group VLAN Registration Protocol (GVRP) enables the port to dynamically become a member
of a VLAN. GVRP is Disabled by default.
Ingress Checking:
This field can be toggled using the space bar between Enabled and Disabled. Enabled
enables the port to compare the VID tag of an incoming packet with the PVID number assigned to the port. If
the two are different, the port filters (drops) the packet. Disabled disables ingress filtering. Ingress Checking
is
Disabled
by default.
Acceptable Frame Type:
This field denotes the type of frame that will be accepted by the port. The user
may choose between
Tagged Only
, which means only VLAN tagged frames will be accepted, and Admit_All,
which mean both tagged and untagged frames will be accepted.
Admit_All
is enabled by default.

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. 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.
Figure 5.32 – VLAN > Voice VLAN > Voice VLAN Global Settings
Voice VLAN State:
Select to Enable or Disable Voice VLAN. The default is
Disabled.
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
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.
Priority:
The 802.1p priority levels of the traffic in the Voice VLAN. The default priority is highest.
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.
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 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.
