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.
