4. 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 (modemwwan2). 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)
(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>
Note If the reboot parameter is enabled at the same time as the restart parameter, the reboot
parameter takes precedence.
(Optional) Set the number of times that the Surelink test must fail before the device is
n
rebooted:
(config network interface my_wan ipv4 surelink)> reboot_attempts int
(config network interface my_wan ipv4 surelink>
where int is any number greater than 0. The default is 1.
7. Add a test target:
(config network interface my_wan)> add ipv4 surelink target end
(config network interface my_wan ipv4 surelink target 0)>
