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.   
Security 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.
