Network Failover General Settings




Enable IP Network Failover: Enable the Network Failover feature in the Digi device.
Click the checkbox to turn failover on or off.
Enable fallback to the non-failover default gateway priority method: The fallback
option is used if a default gateway cannot be configured by Network Failover. Failure to
configure a default gateway could occur if one or more interfaces are not enabled (On)
for Network Failover use, or if the enabled interfaces are not Up or do not have a
gateway associated with them. Click the checkbox to turn fallback on or off.
Failover Interface Priority: The list of available network interfaces in priority order,
used by failover to determine the default gateway. The default gateway is used to route
IP packets to an outside network, unless controlled by another route.
A network interface may have a static gateway configured for it, or it may obtain a
gateway from DHCP or other means when the interface is configured. The first interface
in this list that supplies a gateway will be used as the default gateway. The default
gateway may change as interfaces connect and disconnect, and as failover link tests
determine that an interface is providing the desired IP packet routing to a remote
network destination.
To change the interface priority order, select an item from the list and click the up or
down arrow.
Link Test Settings for each of the network interfaces: The options that follow are
used to configure the link tests for the network interfaces. Each network interface has its
own set of options. Failover can support the use of Ethernet, Wi-Fi and Mobile (cellular)
network interfaces. The available interfaces vary among different Digi products.

destination must be a valid IPv4 address. If the destination is left empty, no Primary
Destination link test will be attempted.
The destination must be a valid IPv4 address. If the destination is left empty, no
Secondary Destination link test will be attempted.
link test. When a reply is received, the ping test ends successfully and does not
continue to send ping requests. If no ping reply is received after Send Count ping
requests have been sent, the link test ends in failure.
Enable IP Network Failover for the XXX Interface: Enable use of the XXX interface
for failover, where XXX is Ethernet, Wi-Fi, or Mobile. Click the checkbox to turn
failover on or off. If a network interface is not enabled for use by failover, it will not be
considered by failover for use in selecting the default gateway.
No Test: Click on the radio button to select no link tests will be used for this interface.
Since no link tests are run, failover will only be aware of the Up or Down status of the
interface.
Ping Test: Click on the radio button to select the Ping Test as the link test to use for this
interface. The Ping Test sends ICMP Echo Request packets to the configured
destination IP address. If an ICMP Echo Reply is received (ping reply), the link test has
successfully demonstrated that the network interface can be used to communicate with
the specified destination.
Primary Destination (Ping Test): The primary, or first, destination to ping. The
Secondary Destination (Ping Test): The secondary, or second, destination to ping.
Send Count (Ping Test): The maximum number of ping requests to send for a ping
