There are two voice VLAN modes on a port: automatic and manual. You can configure
the voice VLAN mode of a port according to data stream passing through the port.
In automatic voice VLAN mode: In automatic voice VLAN mode, the system
identifies the source MAC address contained in the untagged packet sent when
the IP phone is powered on and matches it against the OUI addresses. If a match
is found, the system will automatically add the port into the voice VLAN. An aging
time can be configured for the voice VLAN. The system will remove a port from the
voice VLAN if no voice packet is received from it after the aging time. The adding
and deleting of ports are automatically realized by the system.
In manual voice VLAN mode: administrators need to execute related commands
to add an IP phone access port to the voice VLAN or remove an IP phone access
port from the voice VLAN.
For the tagged packets sent by IP voice devices, they are processed in the same way in
either of the above two modes: forwarded within corresponding VLAN according to
their VLAN ID in the tags.
Voice VLAN packets can be forwarded by trunk ports and hybrid ports in voice VLAN.
You can enable a trunk port or a hybrid port belonging to other VLANs to forward voice
and service packets simultaneously by enabling the voice VLAN function for it.
As multiple types of IP voice devices exist, you need to match the voice VLAN mode of
a port with the type of voice stream sent by IP voice devices, as listed in
