a Wireless Wide Area Network
To edit an existing WAN or WWAN, change to the WAN or WWAN's node in the
n
configuration schema. For example, for a WAN or WWAN 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 (eth1) and WWAN (modemwwan2).
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 IX20
device to automatically recover the modem in the event that it cannot obtain an IP address.
See Configure a Wireless Wide Area Network (WWAN)
(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.
