Table 4-5 Network parameters (1)
Parameter Description
Network 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.
