Interfaces
5. After creating or selecting the WAN or WWAN, click IPv4 (or IPv6) > SureLink.
6. Enable SureLink.
SureLink can be enabled for both IPv4 and IPv6 configurations. By default, SureLink is enabled
for IPv4 for the preconfigured WAN (ETH1) and WWAN (Modem). It is disabled for IPv6.
When SureLink is configured for Wireless WANs, SureLink tests are only run if the cellular
modem is connected and has an IP address. Use the SIM failover options to configure the IX30
device to automatically recover the modem in the event that it cannot obtain an IP address.
See Configure a Wireless Wide Area Network (WWAN)
7. Restart interface is enabled by default.
(Optional) For Restart fail count, type or select the number of times that the Surelink
n
test must fail before the interface is restarted. The default is 1.
8. (Optional) If the interface is a WWAN, Reset modem is enabled by default. To disable, toggle
off Enable.
(Optional) For Reset modem fail count, type or select the number of times that the
n
Surelink test must fail before the modem is reset. The default is 3.
9. If the interface is a WWAN, Switch SIM is enabled by default. Click to disable.
If Switch SIM is enabled, for Switch SIM fail count, type or select the number of times
n
that the Surelink test must fail before the modem switches to the alternate SIM. The
default is 5.
Note The SureLink Switch SIM option differs from the SIM failover option, which is set during
WWAN configuration. SIM failover applies when the modem is unable to connect to a cellular
network, whereas Switch SIM applies when the WWAN interface is failing SureLink tests even
though the modem is connected. See
details about SIM failover.
10. (Optional) Enable Reboot device.
If Reboot device is enabled at the same time as either Restart interface or Reset modem,
Reboot device takes precedence.
For Reboot fail count, type or select the number of times that the Surelink test must
n
fail before the device is rebooted. The default is 1.
11. Click to expand Test targets.
