Web Manager Wizard > Configuring Network Interfaces—Wizard > Configuring Failover

Configuring Failover
If failover is enabled on the “Network Interfaces” screen, clicking the “Next” button brings up a screen for configuring the failover device. The following figure shows the fields that appear on the screen for configuring the failover device if the DHCP option is not checked. If the DHCP option is not checked, no further configuration is needed. Clicking the “Next” button brings up the subnet configuration screen.
“Configure Failover Device” Screen
With failover enabled, the secondary Ethernet interface becomes bonded to the primary Ethernet interface, and the secondary Ethernet interface becomes active only if the primary Ethernet port is not available. As a result, the values entered in the fields on the screen shown in “Configure Failover Device” Screen apply to the single bond0 interface.
