Configuring Voice VLAN Properties
Use the Properties page to globally configure the voice VLAN parameters.
To configure the voice VLAN properties:
STEP 1 Click VLAN Management > Voice VLAN > Properties.
STEP 2 Enter the following information:
• Voice VLAN ID—Select the VLAN as the voice VLAN.
• CoS/802.1p—Select the CoS/802.1p value that will be used by LLDP MED
as a voice network policy. The possible values are 0 to 7, where 7 is the
highest priority. 0 is used as a best effort, and is invoked automatically when
no other value has been set (default).
• DSCP—Select the DSCP value that will be used by LLDP MED as a voice
network policy.
• Dynamic Voice VLAN—Select one of the following voice VLAN modes:
-
Enable Auto Voice VLAN
—Select this option to enable the Auto Voice
VLAN mode.
-
Enable Telephony OUI
—Select this option to enable the Telephony OUI
mode.
-
Disable
—Select this option to disable the Voice VLAN.
STEP 3 Click Apply. The VLAN properties are defined, and the Running Configuration is
updated.
Configuring Telephony OUI
Organizationally Unique Identifiers (OUIs) are assigned by the Institute of Electrical
and Electronics Engineers, Incorporated (IEEE) Registration Authority. Since the
number of IP phone manufacturers is limited and well-known, the known OUI
values cause the relevant frames, and the port on which they are seen, to be
automatically assigned to a voice VLAN.
The OUI Global table can hold up to 16 OUIs.
