establishes (or refuses) the TCP connection, the test fails. The primary and secondary addresses may
be either IP addresses or fully qualified domain names.
n
TCP Port : The TCP port number to connect to on the remote host. The default is 80.
DNS Lookup Test
nables or disables the use of a Domain Name Server (DNS) lookup as a test to verify the integrity of
the mobile connection. The test is successful if the DNS server sends valid reply. Typically, this means
the hostname is successfully “resolved” to an IP address by a DNS server. But even a reply such as
“not found” or “name does not exist” is acceptable as a successful test result, because that
demonstrates successful two-way communication over the mobile connection. When a valid reply is
received, the test completes successfully and immediately.
This test uses the primary and secondary DNS server obtained from the mobile network when the
PPP connection is first established. You can view these addresses on the
Administration > Mobile
Status page.
Note The LTE modem does not use a PPP connection.
Device Cloud Connection Test
Enables or disables verification of the Remote Manager connection. The test is successful if you can
establish a connection to the configured Remote Manager server, and if you can exchange keep-alive
messages with the server. The test fails if you cannot establish a connection or if keep-alive messages
stop. You can configure the Remote Manager server on the
Advanced Configuration > Device Cloud
Connectivity page.

Domain Name Server (DNS) Configuration page
In this page you can configure the Domain Name System servers to be used as static servers when
dynamic mechanisms do not supply enough DNS servers. The IP addresses of Domain Name Servers
(DNS) used to resolve computer host names to IP addresses. Static DNS servers are specified
independently of any network interface and its connection state. An IP address of 0.0.0.0 indicates no
server is specified.

Primary DNS : The name of the primary DNS server.
