Using Autoconfigure and Autoexecute Files
Two features allow you automatically execute scripts that can manage the switch configuration.
Configuration commands placed in the default.xsf file are executed by the switch as it comes up and is unable to find its usual configuration file or if the switch is unconfigured or if the configuration file cannot be determined due to a corrupt NVRAM.
This returns the switch to some basic configuration. When default.xsf is executed, the show switch command shows default.xsf as the booted configuration file.
The default.xsf file can have any CLI commands as long as they are all executed within 500 seconds.
The script is aborted when the commands are not executed within that time. When the file is loaded, the results can be seen by executing the show script output default command.
Configuration commands placed in the autoexec.xsf file are executed after a switch loads its configuration.
The file is not executed when a default.xsf file has been executed. Use the file to execute commands after a switch is up and running and also to revert changes made to the configuration by UPM scripts that run persistent commands. The commands must be executed within 500 seconds or the script execution is aborted.
When an autoexec.xsf file is executed. the results can be seen by executing the show script output autoexec command.
