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.

Processing Mode
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.
The processing mode for the device to deal with the packet
is determined by whether the port permits
not, independent of voice VLAN security mode.
Do not check the source MAC address of the packet and all
the packets can be transmitted in the voice VLAN.
The processing mode for the device to deal with the packet
