¾Security 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.

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.
