Use multiple configuration files to test the configuration on remote devices
You can use multiple configuration files, along with the autorun on page 141 command, to test a new
configuration on a remote device that might result in the remote device going offline, in which case
the device cannot be remotely accessed.
To test the configuration on a remote device, create a new configuration file with desired
configuration changes to test. In addition to the desired configuration changes, the file should
contain two
autorun on page 141 commands:
n
The first autorun on page 141 command automatically reverts the device to use the original
configuration file.
n
The second autorun on page 141 command schedules a reboot after a period of time.
Example test configuration file
For example, suppose you creates a new test configuration file named test.cfg
This test.cfg file changes the cellular 1 apn parameter, and executes two autorun on page 141
commands to automatically revert the device back to use the config.da0 configuration file and to
reboot in 5 minutes. It then saves the configuration to test.cfg and reboots the device.
update config test.cfg
cellular 1 apn new-apn-to-test
autorun 1 command “update config config.da0”
autorun 2 command “reboot in 5”
save config
reboot
If the TransPort LR device does not come back online, the device automatically reverts to the old
(working) configuration file,
config.da0 , and reboots after 5 minutes.
If the device comes back online after being rebooted with the configuration (that is, the device
connected with the new cellular APN), you can cancel the scheduled reboot using the
reboot cancel
command.
reboot cancel
Using the copy on page 147 and update on page 211 commands, you can then copy the configuration
file to the final configuration file, and change the configuration file name.
copy test.cfg config.da0
update config config.da0
