Interfaces
In this example configuration, SureLink is used over for the WAN1 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 TX54 device brings the WAN1 interface down and starts using the WWAN1 interface.
If the TX54 device cannot get a connection on the WWAN1 interface, it attempts to use the WWAN2
interface. It continues to regularly test the connection to WAN1 and WWAN1, and when tests on one
of those WANs succeeds, the device falls back to the successful highest priority WAN.
To achieve this WAN failover from the WAN1 to the WWAN1 and WWAN2 interfaces, the WAN failover
configuration is:
WebUI
1. Log into the TX54 WebUI as a user with full Admin access rights.
2. On the menu, click System. Under Configuration, click Device Configuration.
The Configuration window is displayed.
