Figure 11-2 Net Fault-tolerance Working Mode

Working Mode: Two 10M/100M/1000M NIC cards are provided and it allows the

device to work in the Multi-address 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 the default route. When the system is
connecting with the extranet the data is forwarded through the default route.
Net-fault Tolerance Mode: The two NIC cards use the same IP address. You can

set the Main NIC to LAN1 or LAN2. By doing this, the device automatically enables
the standby NIC card ensuring the system runs normally in the event of a NIC card
failure.
