Voice VLANs

The voice VLAN feature enables switch ports to carry voice traffic with defined priority to
enable separation of voice and data traffic coming onto port. Voice VLAN ensures that the
sound quality of an IP phone does not deteriorate 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 clients attached to the network cannot initiate a direct attack on
voice components.
