Introduction to Voice VLAN
Introduction to Voice VLAN
Definition
Voice VLAN is a technology that
transmits voice data.
Purpose
Data, voice, and video services
are often transmitted simultaneously over a network. Voice services,
in particular, require a higher forwarding priority than data or video
services. When bandwidth is limited, voice data must have transmission
preference over other types of data. This can be ensured by configuring
a voice VLAN on the switch to transmit voice data and setting QoS
parameters in the voice VLAN so that voice data is given preference
when congestion occurs.
