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.   

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.   

Table 9-3 Security mode and packets processing mode 

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 and 

aging time.
