Devices	This command is supported in Digi Cellular Family products only.
supported
Purpose	Configures Digi SureLink™ settings for a Digi Cellular Family device. Digi
	SureLink™ provides an “always-on” mobile network connection to ensure
	that a Digi Cellular Family device is in a state where it can connect to the
	network. It does this through hardware reset thresholds and periodic tests
	of the connection.
	There are several groups of command options for “set surelink:”
	• Hardware reset thresholds: these settings can be configured to clear
	any error states that were resident in the device's cellular module, so
	the device can once again connect to the network, if the connection is
	lost. SureLink does this by first resetting the cellular module after a
	default or specified number of consecutive failed connection attempts,
	and then resetting the Digi Cellular device after a default or specified
	number of failed consecutive connection attempts. Each of these
	connection-failure settings can be disabled as well.
	• Link Integrity Monitoring Tests: Digi SureLink can be configured to run
	tests, known as Link Integrity Monitoring tests, that are run over the
	established PPP connection to ensure that end-to-end communication
	is possible. There are command options that apply to all link testing,
	and options for the three available Link Integrity Monitoring tests:
	•	Ping Test
	•	TCP Connection Test
	•	DNS Lookup Test

Syntax	Set Hardware reset thresholds
	set surelink [module_reset_connect_failures={1-2550=off}]
	[system_reset_connect_failures={1-2550=off}]
	Configure Link Integrity Monitoring Tests:
	Set general link test options
	set surelink [state={onoff}]
	[test={pingtcpdns}]
	[trigger={intervalidle}]
	[max_consecutive_failures={1-2550=off}] (probe failures before
	link reset)
	[interval=10-65535]
	Set ICMP ping link test options
	set surelink [pingaddr1={ipv4 addressfqdn}]
	[pingaddr2={ipv4 addressfqdn}]
	Set DNS lookup link test parameters:
	set surelink [dnsfqdn1=dns fqdn]
	[dnsfqdn2=dns fqdn]
