9.8 Vo ic e 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).
