Interfaces
2. At the command line, type config to enter configuration mode:
> config
(config)>
3. Create a new interface, or edit an existing one:
To create a new interface, see
n
or Configure a Wide Area Network (WAN)
(WWAN).
To edit an existing interface, change to the interface's node in the configuration
n
schema. For example, for a interface named my_wan, change to the my_wan node in
the configuration schema:
(config)> network interface my_wan
(config network interface my_wan)>
4. Enable SureLink.
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
(config network interface my_wan> ipv4 surelink enable true
(config network interface my_wan)>
5. By default, the device is configured to restart the interface when its connection is considered
to have failed.
To disable:
(config network interface my_wan ipv4 surelink)> restart false
(config network interface my_wan ipv4 surelink>
(Optional) Set the number of times that the Surelink test must fail before the interface
n
is restarted:
(config network interface my_wan ipv4 surelink)> restart_attempts
int
(config network interface my_wan ipv4 surelink>
where int is any number greater than 0. The default is 1.
6. Set the device to reboot when the interface is considered to have failed:
(config network interface my_wan ipv4 surelink)> reboot true
(config network interface my_wan ipv4 surelink>
