The following table describes the labels in this screen.
9.6 Voice VLAN Setup
Voice VLAN ensures that the sound quality of an IP phone is preserved from deteriorating when the data
traffic on the Switch ports is high. It groups the voice traffic with defined priority into an assigned VLAN
which enables the separation of voice and data traffic coming onto the Switch port.
You can set priority level to the Voice VLAN and add MAC address of IP phones from specific
manufacturers by using its ID from the Organizationally Unique Identifiers (OUI).

Voice VLAN Setup

DESCRIPTION
GVRP
GVRP (GARP VLAN Registration Protocol) is a registration protocol that defines a way for
switches to register necessary VLAN members on ports across the network.
Select this check box to permit VLAN groups beyond the local Switch.
Port
This field displays the port number.
*
Settings in this row apply to all ports.
Use this row only if you want to make some settings the same for all ports. Use this row first to set
the common settings and then make adjustments on a port-by-port basis.
Note: Changes in this row are copied to all the ports as soon as you make them.
Ingress Check
If this check box is selected, the Switch discards incoming frames on a port for VLANs that do
not include this port in its member set.
Clear this check box to disable ingress filtering.
PVID
A PVID (Port VLAN ID) is a tag that adds to incoming untagged frames received on a port so
that the frames are forwarded to the VLAN group that the tag defines.
Enter a number between 1and 4094 as the port VLAN ID.
GVRP
Select this check box to allow GVRP on this port.
Acceptable
Frame Type
Specify the type of frames allowed on a port. Choices are
All
,
Tag Only
and
Untag Only
.
Select
All
from the drop-down list box to accept all untagged or tagged frames on this port.
This is the default setting.
Select
Tag Only
to accept only tagged frames on this port. All untagged frames will be
dropped.
Select
Untag Only
to accept only untagged frames on this port. All tagged frames will be
dropped.
VLAN Trunking
Enable
VLAN Trunking
on ports connected to other switches or routers (but not ports directly
connected to end users) to allow frames belonging to unknown VLAN groups to pass through
the Switch.
Isolation
Select this to allows this port to communicate only with the CPU management port and the
ports on which the isolation feature is not enabled.
Apply
Click
Apply
to save your changes to the Switch’s run-time memory. The Switch loses these
changes if it is turned off or loses power, so use the
Save
link on the top navigation panel to
save your changes to the non-volatile memory when you are done configuring.
