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).
Click the Voice VLAN Setup link in the VLAN Configuration screen to display the configuration screen as
shown.
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.
