Saving Configurations
Whenever configuration changes are made, the modified configuration must be saved so the
changes will not be lost when the system is rebooted. The system uses the configuration and image
files, as well as other operational parameters necessary for system initialization, according to the
locations specified in the boot option file (BOF) parameters. For more information about boot
option files, refer to the
Boot Option Files section of this manual.
Configuration files are saved by executing implicit or explicit command syntax.
• An explicit save writes the configuration to the location specified in the
save
command
syntax (the file-url option).
• An implicit save writes the configuration to the file specified in the primary configuration
location.
If the file-url option is not specified in the
save
command syntax, the system attempts to
save the current configuration to the current BOF primary configuration source. If the
primary configuration source (path and/or filename) changed since the last boot, the new
configuration source is used.
The
save
command includes an option to save both default and non-default configuration
parameters (the detail option).
The index option specifies that the system preserves system indexes when a save command is
executed, regardless of the persistent status in the BOF file. During a subsequent boot, the index
file is read along with the configuration file. As a result, a number of system indexes are preserved
between reboots, including the interface index, LSP IDs, path IDs, etc. This reduces
resynchronizations of the Network Management System (NMS) with the affected network
element.
If the save attempt fails at the destination, an error occurs and is logged. The system does not try to
save the file to the secondary or tertiary configuration sources unless the path and filename are
explicitly named with the
save
command.
