Managing Voice VLANs

Voice VLAN Configuration

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.

Voice VLAN Interface Summary

Use this page to configure the per-port settings for the Voice VLAN feature. When Voice VLAN is configured
on a port that receives both voice and data traffic, it can help ensure that the voice traffic has priority.

Description
The administrative mode of the Voice VLAN feature. Click Enable or Disable (default) to administratively
turn the Voice VLAN feature on or off for all ports. When Voice VLAN is enabled globally and
configured on interfaces that carry voice traffic, this feature can help ensure that the sound quality of
an IP phone does not deteriorate when data traffic on the port is high.
