Security Mode of Voice VLAN
When voice VLAN is enabled for a port, you can configure its security mode to filter data stream. If
security mode is enabled, the port just forwards voice packets, and discards other packets whose
source MAC addresses do not match OUI addresses. If security mode is not enabled, the port
forwards all the packets.

When the source MAC address of the packet is the
OUI address that can be identified, the packet can be
transmitted in the voice VLAN. Otherwise, the packet
will be discarded.
Enable
Packet with other VLAN
TAG
The processing mode for the device to deal with the
packet is determined by whether the port permits
the VLAN or not, independent of voice VLAN security
mode.
UNTAG packet
Packet with voice VLAN
TAG
Do not check the source MAC address of the packet
and all the packets can be transmitted in the voice
VLAN.
Disable
Packet with other VLAN
TAG
The processing mode for the device to deal with the
packet is determined by whether the port permits
the VLAN or not, independent of voice VLAN security
mode.

Note:
Don’t transmit voice stream together with other business packets in the voice VLAN except for
some special requirements.
The Voice VLAN function can be implemented on
Global Config, Port Config
and
OUI Config
pages.

On this page, you can configure the global parameters of the voice VLAN, including VLAN ID,
aging time, the transmission priority of the voice packets and so on.
