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
n
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.

network, whereas Switch SIM applies when the WWAN interface is failing SureLink tests even
though the modem is connected. See
more information about the SIM failover option.
