Port Voice VLAN Mode
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.
