Voice VLAN
A Voice VLAN is VLAN configured specially for voice traffic. By adding the ports with voice devices attached to
voice VLAN, you can perform QoS-related configuration for voice data, ensuring the transmission priority of
voice traffic and voice quality.
Configuration
The Voice VLAN feature enables voice traffic forwarding on the Voice VLAN, then the switch can classify and
schedule network traffic. It is recommended that there be two VLANs on a port - one for voice, one for data.
Before connecting the IP device to the switch, the IP phone should configure the voice VLAN ID correctly. It
should be configured through its own GUI.
