Clicking the Edit button in the Configuration section of the tab displays the

When should you use the Save System Configuration command?
Whenever you want to permanently save the changes you’ve made to the
parameter settings on the management card. You aren’t, however,
required to enter the command after every change. That’s because the
command copies all of the management card’s settings to permanent
storage, not just your last change. Instead, you might make it a practice to
enter the command at the end of your management sessions, just before
logging off.
Saving the
Configurations of
the Local AT-CM
Line Cards
How do you save your changes to the parameter settings on the AT-CM
Line Cards? Actually, you don’t have to because the line cards do it for
you, automatically. Each line card maintains in its flash memory a
configuration file that it updates whenever you enter a new value for a
parameter setting. Since the file is in flash memory, the contents are
retained even when the line card is reset or is not operating. For example,
if you were to disable a port on a line card or change a port’s speed, and
immediately afterwards were to remove the line card or power off the
chassis, the card would still retain your new setting.
You can, however, save the configuration settings of the AT-CM Line
Cards in the master configuration file on the AT-CV5M02 Management
Card, from where they can be restored to the line cards, should that ever
prove necessary. For example, if you replaced a line card, you could
restore the previous configuration stored on the management card to the
new card, thereby giving the new line card the same configuration at its
predecessor. This relieves you from having to adjust the settings
manually.
There are several commands for saving a line card’s configuration in the
master configuration file. You can save the changes to each card
individually, or you can save the changes to all of the line cards at the
same time. If you’re configuring just one card, the former might be easier.
