Enter the custom command to test the connection in the Test Command field. An example script
is as follows:
myscript 5 10 ping -c 1 -I
$if_netdev
15.1.2.3
Replace
$if_netdev
with the name of the network interface on which you are running the test, such
as
ppp0
.
b
Click Finish. If the Test Command exits with a return code of zero (0), the connection passed the
test and is considered up; otherwise, the connection is considered down.
The next step is to modify the failover levels. See To modify failover levels .
To modify failover levels
The next step of configuring Internet failover is associating Internet connections with primary, secondary,
and optionally tertiary connection levels. Recall that a connection level is one or more connections. These
connections must be marked as Required or Enabled. Internet connections that are marked Disabled
are not part of this connection level. The initial defaults on the modify levels page for a connection are:
• Load balancing — Disabled
• Primary — Enabled
• Secondary — Enabled
• Tertiary — Enabled
A connection level is deemed to be up when all connections marked Required at that level are up, and at
least one connection marked Required or Enabled at that level is also up.

From the Network Setup menu, click Network Setup, select the Failover & H/A tab and click the
Modify Levels button. A table is displayed listing each of the connections alongside a list for each
connection level (
Figure 73 ).

First, configure the Primary connection level by selecting an option from the Primary list. If you only have
a single Internet connection, setting the level to Enabled or Required has the same effect.

For failover to succeed, you must then configure at least the Secondary connection level for another port
or ports. Select Enabled or Required from the Secondary list.
