Basic Configuration
5.10. Save User Selected Parameters
It is strongly recommended to save all user-defined parameters to a file as described
in Section 15. This will allow quick recovery in the event of accidental deletion or
reconfiguration of port parameters.
When changing configuration parameters via the Text Interface, make certain that the
VMR/NPS has saved the newly defined parameters before exiting from command mode.
To save parameters, press the [Esc] key several times until you have exited from all
configuration menus and the VMR/NPS displays the "Saving Configuration" menu and
the cursor returns to the command prompt. If newly defined configuration parameters
are not saved prior to exiting from command mode, then the VMR/NPS will revert to the
previously saved configuration after you exit from command mode.
5.10.1. Restore Configuration
If you make a mistake while configuring the VMR/NPS unit, and wish to return to the
previously saved parameters, the Text Interface's "Reboot System" command (/I) offers
the option to reinitialize the unit using previously backed up parameters. This allows
you to reset the unit to previously saved parameters, even after you have changed
parameters and saved them.
Notes:
• The VMR/NPS will automatically backup saved parameters once a day,
shortly after Midnight. This configuration backup file will contain only the
most recently saved VMR/NPS parameters, and will be overwritten by the next
night's daily backup.
• When the /I command is invoked, a submenu will be displayed which offers
several Reboot options. Option 5 is used to restore the configuration backup
file. The date shown next to option 5 indicates the date that you last changed
and saved unit parameters.
• If the daily automatic configuration backup has been triggered since the
configuration error was made, and the previously saved configuration has
been overwritten by newer, incorrect parameters, then this function will not
be able to restore the previously saved (correct) parameters.
To restore the previously saved configuration, proceed as follows:
1. Access command move via the Text Interface, using a username/password that
permits access to Administrator level commands (see Section 5.1.1.)
2. At the VMR/NPS command prompt, type /I and press [Enter]. The VMR/NPS will
display a submenu that offers several different reboot options.
3. At the submenu, choose Item 5 (Reboot & Restore Last Known Working
Configuration. Key in the number for the desired option, and then press [Enter].
4. The VMR/NPS will reboot and previously saved parameters will be restored.
