6.2 Rollback Operations

The FibeAir 70 system supports rolling back of network configurations.

A rollback is a safety measure to prevent unwanted System changes in the event that a loss

of communication occurs while performing 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.

6.2.1 Rollback Commands

6.2.1.1 Setting Rollback Timeout

o specify the System 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 (i.e., the

timeout duration is reached), 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.

6.2.1.2 Clearing Rollback Timeout

To remove the System rollback timeout period, use the following command:

clear rollback

Issuing this command cancels the rollback function. This means that the System will not

automatically roll back to any previous configuration.

The clear rollback command may be entered at any time before the end of a rollback

timeout period in order to cancel a rollback timeout.

6.2.1.3 Showing Rollback Timeout

Display the System rollback timeout period using the Show command:

show rollback [{info | timeout}]
