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.
Default Ethernet Port
In the Ethernet Card list, select an Ethernet port as a default
port.
This setting is available only when the
Multi-address
is selected
in the Net Mode list.
IP Version
In the IP Version list, you can select IPv4 or IPv6 . Both versions
are supported for access.
MAC Address Displays the MAC address of the Device.
