Security Mode of Voice VLAN
When voice VLAN is enabled for a port, it 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.
