Parameter Description
Net Mode
Multi-address : Two Ethernet ports work separately through either

of which you can request the Device to provide the services such
as HTTP and RTSP. You need to configure a default Ethernet port
(usually the Ethernet port 1 by default) to request the services from
the device end such as DHCP, Email and FTP. If one of the two
Ethernet ports is disconnected as detected by networking testing,
the system network status is regarded as offline.
Fault Tolerance : Two Ethernet ports share one IP address.

Normally only one Ethernet port is working and when this port fails,
the other port will start working automatically to ensure the network
connection.
When testing the network status, the network is regarded as offline
only when both of the two Ethernet ports are disconnected. The
two Ethernet ports are used under the same LAN.
Load Balance : Two network cards share one IP address and they

are working at the same time to share the network load averagely.
If one of them fails, the other can continue working normally.
When testing the network status, the network is regarded as offline
only when both of the two Ethernet ports are disconnected. The
two Ethernet ports are used under the same LAN.
The Device with single Ethernet port does not support this function.
