This mode saves the file morequickly but is likely to lose the existing configuration file if the device reboots or the power failsduring the process. The fast saving mode is suitable for environments where the power supply isstable.• Safe saving: Executing the save command with the safely keyword. The mode saves the file moreslowly but can retain the configuration file in the device even if the device reboots or the power failsduring the process. The safe saving mode is preferred in environments where a stable power supplyis unavailable or remote maintenance is involved.Follow these steps to save the current configuration of the router:To do… Use the command… RemarksSave the current configuration to thespecified file, but the configuration file willnot be set as the file for the next startupsave file-urlSave the current configuration to the rootdirectory of the storage medium andspecify the file as the startup configurationfile that will be used at the next systemstartupsave [ safely ]Use either commandAvailable in any viewNOTE:• The configuration file must be with extension .cfg.• During the execution of the save command, the startup configuration file to be used at the next systemstartup may be lost if the device reboots or the power supply fails.
