The system uses the source MAC of the traffic traveling through the port to identify the 
IP Phone data flow. You can either preset an OUI address or adopt the default OUI 
address as the standard. Here the OUI address refers to that of a vendor. 
Voice VLAN can be configured either manually or automatically. In auto mode, the 
system learns the source MAC address and automatically adds the ports to a Voice 
VLAN using the untagged packets sent out when IP Phone is powered on; in manual 
mode, however, you need to add ports to a Voice VLAN manually. Both of the modes 
forward the tagged packets sent by IP Phone without learning the address.  
Since there are multiple types of IP Phones, you must ensure that the mode on a port 
matches the IP Phone. Please see the following table:
