Interfaces
1. Log into the Connect EZ 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. Create a new WAN or WWAN, or edit an existing one:
To create a new WAN or WWAN, see
n
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.
SureLink can be enabled for both IPv4 and IPv6 configurations. By default, SureLink is enabled
for IPv4 for the preconfigured WAN (eth1) and WWAN (modemwwan2). It is disabled for IPv6.
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
Connect EZ device to automatically recover the modem in the event that it cannot obtain an IP
address. See
(config network interface my_wan> ipv4 surelink enable true
(config network interface my_wan)>
5. By default, the device is configured to restart the interface when its connection is considered
to have failed.
To disable:
(config network interface my_wan ipv4 surelink)> restart false
(config network interface my_wan ipv4 surelink>
(Optional) Set the number of times that the Surelink test must fail before the interface
n
is restarted:
(config network interface my_wan ipv4 surelink)> restart_attempts
int
(config network interface my_wan ipv4 surelink>
where int is any number greater than 0. The default is 1.
6. (Optional) If the interface is a WWAN, set the device to reset the modem:
(config network interface my_wan ipv4 surelink)> reset_modem true
(config network interface my_wan ipv4 surelink>
