Voice VLAN
The voice VLAN feature enables switch ports to carry voice traffic with defined settings so
that voice and data traffic are separated when coming onto the port. A voice VLAN ensures
that the sound quality of an IP phone is safeguarded from deterioration when data traffic on the
port is high.
The inherent isolation provided by VLANs ensures that inter-VLAN traffic is under
management control and that network-attached clients cannot initiate a direct attack on voice
components. A QoS protocol based on the IEEE 802.1P class-of-service (CoS) protocol uses
classification and scheduling to send network traffic from the switch in a predictable manner.
The system uses the source MAC of the traffic traveling through the port to identify the IP
phone data flow.
Voice VLAN is enabled per-port basis. A port can participate only in one voice VLAN at a
time. The Voice VLAN feature is disabled by default.
