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.
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.
