Using the Web Manager : Web Manager Wizard : Configuring network interfaces

Configuring network interfaces
Figure 6.6 shows the first of a series of related screens that appears when the Network interfaces option is selected from the Wizard menu.
Network Interfaces Screen
The screen shown in Figure 6.6 allows the administrative user to set or change the parameters in the following table.
Selecting enabled from the pull-down menu configures failover from the primary to the secondary Ethernet port if the primary port goes down. For background information, see Ethernet Ports on the OnBoard Appliance.
Clicking the Next button on the Network Interfaces screen brings up one of two screens, depending on whether failover is enabled or disabled. See Configuring failover and Configuring primary and secondary Ethernet ports.
Table 6.2 describes the parameters that can be set on the failover configuration screen and on the primary and secondary Ethernet configuration screens.
DHCP is enabled by default on the OnBoard appliance’s interfaces. If DHCP is enabled, the OnBoard appliance looks for a DHCP server on the same network. If a DHCP server cannot be located, the OnBoard appliance falls back to using the default IP address described below. The additional fields in the table rows below appear only if DHCP is not checked, because they are needed only when configuring a static IP address for the interface.
Configuring routes
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 should go to the Network-Static routes screen.
Configuring failover
If failover is enabled on the Network Interfaces screen, clicking the Next button brings up a screen for configuring the failover device. Figure 6.7 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 Figure 6.7 apply to the single bond0 interface.
Configuring primary and secondary Ethernet ports
If failover is disabled, the administrative user can configure each Ethernet port separately in the following ways:
When failover is disabled on the Network Interfaces screen, clicking the Next button brings up the first of two screens for configuring the primary and secondary Ethernet ports. The screen for configuring the secondary Ethernet port is identical to the screen for the primary Ethernet port except for the screen’s heading.
Figure 6.8 shows the screen for configuring the primary Ethernet connection with the additional fields that appear when the DHCP button is not checked. The administrative user enters the required information on this screen for configuring the OnBoard appliance to use a static IP address.
Configure Primary Ethernet Connection Screen: Static IP
Clicking the Next button on the primary Ethernet configuration screen brings up a screen for configuring the secondary Ethernet connection. Clicking the Next button on the secondary Ethernet configuration screen brings up the next Wizard screen for configuring subnets.

If failover is disabled, clicking the Next button brings up the first of two screens for configuring the primary and secondary Ethernet ports.
NOTE: Connecting the secondary Ethernet port to a separate network and assigning a separate IP address is optional, so you can skip the screen for configuring the secondary Ethernet port, if desired.
If failover is enabled, clicking the Next button brings up a screen for configuring the failover device.
