Security Mode of Voice VLAN
On the WX3000 devices, a voice VLAN can operate in the security mode. Voice VLANs operating in this
mode only permit voice data, enabling you to perform voice traffic-specific priority configuration. With
the security mode disabled, both voice data and service data can be transmitted in a voice VLAN.
Voice VLAN Configuration
Configuration Prerequisites
z
Create the corresponding VLAN before configuring a voice VLAN.
z
VLAN 1 (the default VLAN) cannot be configured as a voice VLAN.
