Saving The Current Configuration - Juniper SYSTEM BASICS - CONFIGURATION GUIDE V 11.1.X Configuration Manual

NOTE: The autocfg.scr script is bypassed if you arm the system to load from a script
(not autocfg.scr) through the boot config command or boot backup command.

Saving the Current Configuration

By default, the system automatically saves any change to the system configuration
to nonvolatile storage (NVS). This feature is known as Automatic Commit mode, but
has no effect on the CLI prompt. For more information about displaying the current
configuration of the system while in Automatic Commit mode, see "show
configuration" on page 268 on "show configuration" on page 268.
You can disable this feature by issuing the service manual-commit command. In
Manual Commit mode (again with no effect on the CLI prompt), any configuration
change affects only the current system configuration (the running configuration). For
more information about displaying the running configuration of the system while in
Manual Commit mode, see "show running-configuration" on page 270 on "show
running-configuration" on page 270.
If you are in Manual Commit mode and want to save the configuration changes to
NVS, you must issue either the write memory command or the copy
running-configuration startup-configuration command.
If you change the configuration while in Manual Commit mode and issue the reload
command without saving the changes to the startup configuration, the system
provides a warning, allowing you to save the changes before reloading.
You can use the include-text-config keyword with the copy running-configuration
command to add the text configuration to the system configuration file in compressed
format. Storing the text configuration in compressed format reduces the size of the
system configuration file and the amount of space that the file occupies on the local
flash card or network host. If you change from commit mode to manual-commit
mode, the configuration that is available at that point in time is written into the .cnf
file. A Perl script is provided in the Tools folder of the software image bundle that
you can download from the Juniper Networks website, depending on whether you
want to install the software on an ERX model or an E120 and E320 model, shipped
with your router that enables you to view the text configuration in a configuration
file that contains both binary and text configuration. The Perl script supports multiple
platforms. The "Usage and Troubleshooting document for desktop tool" file in PDF
format provides an explanation of how to extract the system configuration file, using
the extractScrFromCnf.pl script. For more information about using the Perl script,
see "Using the Desktop Tool for Viewing Uncompressed Text Configuration" on
page 280.
NOTE: To avoid any discrepancies between the text-generated file and the system
configuration file, do not change the configuration when the copy
running-configuration command is running.
