3. Create a new interface, or edit an existing one:
n
To create a new interface, see Configure a Local Area Network (LAN), Configure a Wide
Area Network (WAN), or Configure a Wide Area Network (WAN) or Configure a Wireless
Wide Area Network (WWAN).
n
To edit an existing interface, change to the interface'snode 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 isenabled for the preconfigured WAN (eth1) and WWAN (modemwwan2).
The default configuration tests the DNSservers configured for the interface.
When SureLink is configured for Wireless WANs, SureLink tests are only run if the cellular
modem is connected and hasan IPaddress. Use the SIM failover optionsto configure the IX20
device to automatically recover the modem in the event that it cannot obtain an IPaddress.
See Configure a Wireless Wide Area Network (WWAN) for details about SIM failover.
(config network interface my_wan)> surelink enable true
(config network interface my_wan)>
5. By default, the Test DNS serversconfigured for thisinterface test isautomatically
configured and enabled. Thistests communication with DNSservers 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)>
e. Set the test type:
(config network interface my_wan surelink tests 1)> test value
(config network interface my_wan surelink tests 1)>
