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.

Mode
Packet Type
Processing Mode
UNTAG packet
Packet with voice VLAN TAG
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.
