Interfaces
If the type of probe test is:
n
Ping: Configure the number of bytes in the ping packet.
l
Interface status: Configure the amount of time that the interface is down before it is
l
considered to have failed, and the amount of time it takes to make an initial connection
before it is considered down.
Additional test targets.
n
If more than one test target is configured, determine whether the interface should fail over
n
based on the failure of one of the test targets, or all of the test targets.
Order of precedence for SureLink actions
If multiple SureLink actions, such as restarting the interface and rebooting the device, are enabled,
the following order of precedence is used:
1. Restart interface
2. Switch to the alternate SIM (for WWANs)
3. Reset the modem (for WWANs)
4. Reboot the device
For example, if SureLink is configured as follows:
Restart interface:
n
Enabled
l
Restart fail count: 2
l
Reset modem:
n
Enabled
l
Reset mode fail count: 3
l
Switch SIM:
n
Enabled
l
Switch SIM fail count: 5
l
Reboot device:
n
Enabled
l
Reboot fail count: 7
l
SureLink will: The device will:
1. First SureLink failure: Nothing will happen.
2. Second SureLink failure: The interface will restart.
3. Third SureLink failure: The modem will reset.
4. Fourth SureLink failure: The interface will restart again.
5. Fifth SureLink failure: The device will switch to the alternate SIM.
Note The Switch SIM behavior only applies if the modem is connected, but SureLink tests are
failing. If the modem is not connected, SIM failover applies. See
Area Network (WWAN)
IX30 User Guide
for details about SIM failover.
