9.8 Voice VLAN
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.
