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.
