Voice VLAN configuration  
The Voice VLAN Configuration page contains the Voice VLAN feature. This enables 
voice traffic forwarding on the Voice VLAN, permitting the switch to classify and 
schedule network traffic. We recommended that there be two VLANs on a port – one 
for voice and 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.
