Interfaces
2. At the command line, type config to enter configuration mode:
> config
(config)>
3. Create a new interface, or edit an existing one:
n
To create a new interface, see
Area Network
Wide Area Network
n
To edit an existing interface, change to the interface's node in the configuration
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.
By default, SureLink is enabled for the preconfigured WAN (wan1) and WWAN (wwan1wwan2).
The default configuration tests the DNS servers configured for the interface.
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
TX40 device to automatically recover the modem in the event that it cannot obtain an IP
address. See
(config network interface my_wan)> surelink enable true
(config network interface my_wan)>
5. By default, the Test DNS servers configured for this interface test is automatically
configured and enabled. This tests communication with DNS servers that are either provided
by DHCP, or statically configured for this interface.
To add additional tests:
a. Add a test:
(config network interface my_wan)> add surelink tests end
(config network interface my_wan surelink tests 1)>
b. New tests are enabled by default. To disable:
(config network interface my_wan surelink tests 1)> enable false
(config network interface my_wan surelink tests 1)>
c. Create a label for the test:
(config network interface my_wan surelink tests 1)> label string
(config network interface my_wan surelink tests 1)>
d. if the test should apply to both IPv6 rather than IPv4, enable IPv6:
(config network interface my_wan surelink tests 1)> ipv6 true
(config network interface my_wan surelink tests 1)>
