2-16 VOICE VLAN
Voice VLAN is VLAN configured specially for voice traffic. By adding the ports with voice
devices attached to voice VLAN, we can perform QoS-related configuration for voice data,
ensuring the transmission priority of voice traffic and voice quality.
2-16.1 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.

1. Select “Enabled” in the Voice VLAN Configuration.
2. Specify VLAN ID Aging Time Traffic Class.
3. Specify (Port Mode,Security,Discovery Protocol)
