Using the Web Manager : Web Manager Network Menu Options : Configuring network interfaces

Configuring network interfaces
When an administrative user clicks the Network-Host settings menu option, the following screen appears.
Network-Host Settings Screen
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.
The screen shown above allows an 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.
When configuring public Ethernet ports, be aware of the following:
When an interface is configured for DHCP and the DHCP server cannot be reached for any reason, the interface IP address falls back to the preconfigured default static IP address (192.168.160.10) unless an OnBoard appliance administrator has assigned an IP address to the interface.
When both interfaces are active and assigned two different IP addresses, both interfaces are reachable through either IP address even if the cable is disconnected from one of the interfaces.
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 use the Network-Static routes screen.
Configuring failover
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.
Network-Host Settings Screen With Failover Enabled
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.
Configuring primary and secondary Ethernet ports
If failover is disabled, the administrative user can configure each Ethernet port separately in the following ways:
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.
