Configuration from the Web interface
51
 Repeat the selected link integrity test every N seconds: Specifies the interval, in
seconds, at which the selected test is initiated (repeated). A new test will be started every
N seconds while the mobile connection is established. This value must be between 10
and 65535. The default is 240. This setting is used by Ping, TCP Connection, and DNS
Lookup tests only, not iDigi Connection.
If the configured interval is less time than it takes a test to complete, the next test will
not be initiated until the previous (current) test has completed.
 Test only when idle if no data is received for the above period of time: Specifies that
the test repeat interval (above) is to be used as an idle period interval. That is, initiate the
selected link integrity test only after no data has been received for the specified interval
of time. This changes the behavior of the test in that the test interval varies according to
the presence of other data received from the mobile connection. This setting is used by
Ping, TCP Connection, and DNS Lookup tests only, not iDigi Connection.
Although using this idle option may result in less data being exchanged over the mobile
connection, it also prevents the link integrity tests from running as often to verify the
true bi-directional state of that connection.
 Reset or Reconnect the link after the following number of consecutive link integrity
test failures: Specifies that after the configured number of consecutive link integrity test
failures, the mobile connection should be either reset or reconnected:
– Reset: The cellular modem is reset.
– Reconnect: The mobile interface is reconnected.
This value must be between 1 and 255. The default is 3. When the mobile connection is
reestablished, the “consecutive failures” counter is reset to zero.
If the mobile connection is disconnected for any reason (including not as a result of a
link integrity test failure), the consecutive failures count is reset to zero when the mobile
connection is reestablished.
 Primary Test Hostname:
Secondary Test Hostname:
These settings apply to Ping, TCP Connection, and DNS Lookup tests only. Two
hostnames may be configured for the link integrity monitoring test. Hostnames can be
specified in the form of domain names or IP addresses. If the first hostname fails to get a
reply, the same test is attempted for the second hostname. If no reply is received for
either hostname, the test fails. The primary and secondary DNS names should be fully
qualified domain names. Note that the reverse lookup of an IP address is possible, but
that is usually unlikely to succeed in returning a name. Still, such a reverse lookup can
be used to demonstrate the integrity of the mobile connection.
– Primary Test Hostname: The first hostname to look up.
– Secondary Test Hostname: The second hostname to look up (if the first hostname
fails).
Status and statistical information for mobile connections
Once the mobile settings have been configured, you can monitor the status of mobile connections
by going to Administration > Mobile Status. See "Mobile Status" on page 67.
