Device Cloud Connection 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 according to the mobile
network constraints and your preferences.
The link integrity tests are only performed 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, you should configure the settings to guarantee that the mobile connection is actually being
tested.
You can modify the link integrity test settings at any time. These changes go into effect at the start of
the next test interval.
Ping Test
Enables or disables the use of “ping” (ICMP) as a test to verify the integrity of the mobile connection.
The test is successful if a valid ping reply is received in response to the ping request sent. The ping
test sends 1 ping request and waits up to 30 pings for a reply. When a valid reply is received, the test
completes successfully and immediately.
You can configure destination hosts for this test. If the first host fails to reply to the ping request, the
same test is attempted to the second host. If neither host replies to any of the ping requests sent, the
test fails. The primary and secondary addresses may be either IP addresses or fully qualified domain
names.
n
Primary Address
: First host to test.
n
Secondary Address
: Second host to test if the first host fails.
TCP Connection Test
Enables or disables the creation of a new TCP connection as a test to verify the integrity of the mobile
connection. A successful test establishes a TCP connection to a specified remote host and port
number. If the remote host actively refuses the connection request, the test fails. The TCP connection
test waits up to 30 seconds for the connection to be established or refused. When the TCP connection
is established, the test completes successfully, and the TCP connection is closed immediately.
You can configure two destination hosts for this test. If the first host fails to establish (or refuse) the
TCP connection, the same test is attempted to the second host. If neither host successfully
