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.

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.

The processing mode for the device to deal with the

Do not check the source MAC address of the packet and
all the packets can be transmitted in the voice VLAN.
