1. Log into the AnywhereUSB Plus command line as a user with full Admin access rights.
Depending on your device configuration, you may be presented with an Access selection
menu. Type admin to access the Admin CLI.
2. At the command line, type config to enter configuration mode:
> config
(config)>
3. Change to WAN or WWAN's node in the configuration schema. For example, to disable SureLink
for an interface named my_wan:
(config)> network interface my_wan
(config network interface my_wan)>
4. Determine the index number of the target:
(config network interface my_wan)> show ipv4 surelink target
0
interface_down_time 600s
interface_timeout 120s
test interface_up
1
test dns_configured
(config network interface my_wan)>
5. Delete the target:
(config network interface my_wan> del ipv4 surelink target 1
(config network interface my_wan)>
6. Save the configuration and apply the change:
(config network interface my_wan 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
menu. Type quit to disconnect from the device.
Example: Use a ping test for WAN failover from Ethernet to cellular
In this example configuration, the ETH1 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 ETH1 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 AnywhereUSB Plus device brings the ETH1 interface down and starts using the Modem
interface. It continues to regularly test the connection to ETH1, and when tests on ETH1 succeed, the
device falls back to ETH1.
To achieve this WAN failover from the ETH1 to the Modem interface, the WANfailover configuration is:
