Link integrity monitoring settings
Enable Link Integrity Monitoring using the test method selected below:
Enables or disables the link integrity monitoring tests. If this setting is enabled,
the other Link Integrity Monitoring settings may be configured and are used to
verify the functional integrity of the mobile connection. The default is off
(disabled).
There are three tests available:
– Ping Test
– TCP Connection Test
– DNS Lookup Test
You can use these tests to demonstrate that two-way communication is working
over the mobile connection. Several tests are provided because different mobile
networks or firewalls may allow or block Internet packets for various services.
Select the appropriate test may be selected according to mobile network
constraints and your preferences.
The link integrity tests are performed only while the mobile connection is
established. If the mobile connection is disconnected, the link integrity tests are
suspended until the connection is established again.
For the link integrity tests to provide meaningful results, the remote or target
hosts must be accessible over the mobile connection and not through the LAN
interface of the device (if it has one). That is, the settings should be configured
to guarantee that the mobile connection is actually being tested.
The link integrity test settings may be modified at any time. The changes are
used at the start of the next test interval.
