This section describes how to configure voice VLAN. It covers the following topics:

Voice VLAN Properties
Use the Voice VLAN Properties page for the following:
• View how voice VLAN is currently configured.
• Configure the VLAN ID of the Voice VLAN.
• Configure voice VLAN QoS settings.
• Configure the voice VLAN mode (Telephony OUI or Auto Voice VLAN).
• Configure how Auto Voice VLAN is triggered.
To view and configure Voice VLAN properties:
STEP 1 Click VLAN Management > Voice VLAN > Properties.
• The voice VLAN settings configured on the device are displayed in the Voice VLAN 
Settings (Administrative Status) block. 
• The voice VLAN settings that are actually being applied to the voice VLAN 
deployment are displayed in the Voice VLAN Settings (Operational Status) block. 
STEP  2 Enter values for the following Administrative Status fields:
• Voice VLAN ID—Enter the VLAN that is to be the Voice VLAN.
NOTE Changes in the voice VLAN ID, CoS/802.1p, and/or DSCP cause the device to 
advertise the administrative voice VLAN as a static voice VLAN. If the option Auto 
Voice VLAN Activation triggered by external Voice VLAN is selected, then the default 
values need to be maintained.
