Rollback Operations
You can roll back system configurations. This is a safety measure to prevent unwanted
system changes in the event that a loss of communication occurs while perfo rming
configuration activities. The Rollback timeout function reloads the saved startup
configuration in the event that no command is entered within a predefined timeout
period.
A Rollback timeout is especially recommended when configuring remote elements that
are being managed over the link.
To specify the Rollback timeout period, use the following command:
set rollback timeout <duration-in-seconds>
When Rollback is used, a timer will run (and will restart) whenever a CLI command is
entered. In the event that no CLI command is entered within the timeout period, the
system automatically resets and wakes up with the saved startup configuration.
Note that the rollback timer resets to zero after each new CLI command. The rollback
timer expires when it reaches the value specified by
<duration-in-seconds>
.
To cancel a rollback, use the
clear rollback
command. This command cancels the
Rollback function. This means that the System will not automatically roll back to any
previous configuration.
You can enter the
clear rollback
command any time before the end of a Rollback
timeout period in order to cancel a rollback timeout.
Rollback can also be controlled from the Web-EMS main screen.
