Table 9-1 OUI addresses on the switch 

¾

A voice VLAN can operate in two modes: automatic mode and manual mode.   

Automatic Mode: In this mode, the switch automatically adds a port which receives voice packets 

to voice VLAN and determines the priority of the packets through learning the source MAC of the 

UNTAG packets sent from IP phone when it is powered on. The aging time of voice VLAN can be 

configured on the switch. If the switch does not receive any voice packet on the ingress port within 

the aging time, the switch will remove this port from voice VLAN. Voice ports are automatically 

added into or removed from voice VLAN. 

Manual Mode: You need to manually add the port of IP phone to voice VLAN, and then the switch 

will assign ACL rules and configure the priority of the packets through learning the source MAC 

address of packets and matching OUI address. 

In practice, the port voice VLAN mode is configured according to the type of packets sent out from 

voice device and the link type of the port. The following table shows the detailed information.
