Working Mode
There are two 10M/100M/1000M NIC cards provided by the 9600NI-ST/RT/XT series device, and it allows the
device to work in the Multi-address, Load Balance and Net-fault Tolerance modes.
Multi-address Mode: The parameters of the two NIC cards can be configured independently. You can select
LAN1 or LAN2 in the NIC type field for parameter settings.
You can select one NIC card as default route. And then the system is connecting with the extranet the data will be
forwarded through the default route.
Net-fault Tolerance Mode: The two NIC cards use the same IP address, and you can select the Main NIC to
LAN1 or LAN2. By this way, in case of one NIC card failure, the device will automatically enable the other
standby NIC card so as to ensure the normal running of the whole system.
Load Balance Mode: By using the same IP address and two NIC cards share the load of the total bandwidth,
which enables the system to provide two Gigabit network capacity.
