SureLink can be enabled for both IPv4 and IPv6 configurations. By default, SureLink is enabled
for IPv4 for the preconfigured WAN (
WAN1
) and WWANs (
WWAN1
and, for dual-cellular models,
WWAN2
). 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
TX54 device to automatically recover the modem in the event that it cannot obtain an IP
address. See
