When an administrative user clicks the Network-
Host settings menu option, the following screen appears.
An administrative user can use this screen to configure the OnBoard appliance’s network interfaces. The administrative user also can configure DNS for the OnBoard appliance by entering the DNS server and domain name information at the bottom of the screen.
Configuring the network interfaces sets up a default route for the OnBoard appliance. When the DHCP checkbox is checked on any of the network interface screens, the DHCP server assigns the OnBoard appliance a default route. If the DHCP checkbox is not checked, the gateway IP specified by the administrative user in the Gateway IP field is used to create a default route for the interface. If a host or network route is required, the administrative user use the Network-Static routes screen.
Figure 6.66 shows the fields that appear on the Network-Host Settings screen when the
enabled option is selected from the Failover menu and the DHCP option is not checked. If the DHCP option is checked, no further configuration is needed.
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
Figure 6.66 apply to the single bond0 interface.
The example in Figure 6.67 shows the fields that appear on the Network-Host Settings screen when both the primary and secondary Ethernet ports are enabled and DHCP is disabled.
