2. At the command line, type config to enter configuration mode:
> config
(config)>
3. Change to the WAN or WWAN's node in the configuration schema. For example, to disable
SureLink for the Modem interface:
(config)> network interface modem
(config network interface modem)>
4. Determine the index number of the target:
(config network interface modem)> show ipv4 surelink target
0
interface_down_time 600s
interface_timeout 120s
test interface_up
1
test dns_configured
(config network interface modem)>
5. Delete the target:
(config network interface modem> del ipv4 surelink target 1
(config network interface modem)>
6. Save the configuration and apply the change:
(config network interface my_wwan ipv4 surelink)> save
Configuration saved.

7. Type exit to exit the Admin CLI.
Depending on your device configuration, you may be presented with an Access selection

Example: Use a ping test for WAN failover from Ethernet to cellular

In this example configuration, the ETH interface serves as the primary WAN, while the cellular Modem
interface serves as the backup WAN.
In this example configuration, SureLink is used over for the ETH interface to send a probe packet of
size 256 bytes to the IP host 43.66.93.111 every 10 seconds. If there are three consecutive failed
responses, the Connect IT Mini device brings the ETH interface down and starts using the Modem
interface. It continues to regularly test the connection to ETH, and when tests on ETH succeed, the
device falls back to ETH1.
To achieve this WAN failover from the ETH to the Modem interface, the WAN failover configuration is:
