Command line
Active recovery can be configured for both IPv4 and IPv6. These instructions are for IPv4; to configure
IPv6 active recovery, replace ipv4 in the command line with ipv6.
1. Select the device in Remote Manager and click Actions > Open Console, or log into the LR54
local 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 interface, or edit an existing one:
To create a new interface, see
n
Area Network
Wide Area Network
To edit an existing interface, change to the interface's node in the configuration
n
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.
SureLink can be enabled for both IPv4 and IPv6 configurations. By default, SureLink is enabled
for IPv4 for the preconfigured WAN (wan1) and WWAN (wwanwwan2). 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
LR54 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:
