5. After creating or selecting the 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 WWAN (Modem). It is disabled for IPv6.

7. Restart interface is enabled by default.

(Optional) For Restart fail count, type or select the number of times that the Surelink

test must fail before the interface is restarted. The default is 1.

8. (Optional) Enable Reset modem.

(Optional) For Reset modem fail count, type or select the number of times that the

Surelink test must fail before the modem is reset. The default is 1.

9. 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

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 Configure a Wireless Wide Area Network (WWAN) for

more information about the SIM failover option.

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

fail before the device is rebooted. The default is 1.

11. Click to expand Test targets.
