Voice VLAN Commands
This section describes the commands you use for Voice VLAN. Voice VLAN enables switch
ports to carry voice traffic with defined priority so as to enable separation of voice and data
traffic coming onto the port. The benefits of using Voice VLAN is to ensure that the sound
quality of an IP phone could be safeguarded from deteriorating when the data traffic on the
port is high.

traffic coming onto the port. The benefits of using Voice VLAN is to ensure that the sound
quality of an IP phone could be safeguarded from deteriorating when the data traffic on the
port is high.
Also 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. QoS-based on IEEE 802.1P class of service (CoS) uses classification and
scheduling to sent 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.

The switch can be configured to support voice VLAN on a port connecting to the VoIP phone.
When a VLAN is associated with the voice VLAN port, then the VLAN id info is passed onto
the VoIP phone using the LLDP-MED mechanism. The voice data coming from the VoIP
phone is tagged with the exchanged VLAN ID; thus, regular data arriving on the switch is
given the default PVID of the port, and the voice traffic is received on a predefined VLAN. The
two types of traffic are therefore segregated so that better service can be provided to the
voice traffic.
