DELL N3000 User Manual

Managing Images and Files

Each configuration file contains a list of executable CLI commands. The 

commands must be complete and in a logical order, as if you were entering 

them by using the switch CLI.
When you download a startup-config or backup-config file to the switch, the 

new file replaces the previous version. To change the running-config file, you 

execute CLI commands either by typing them into the CLI or by applying a 

configuration script with the script apply command. The startup-config and 

backup-config files can also be applied to the running-config by using the 

script apply command.

When you use configuration scripting, keep the following considerations and 

rules in mind:

• The application of scripts is partial if the script fails. For example, if the 

script executes four of ten commands and the script fails, the script stops 

at four, and the final six commands are not executed.

• Scripts cannot be modified or deleted while being applied.
• Validation of scripts checks for syntax errors only. It does not validate that 

the script will run.

• The file extension must be .scr.
• A maximum of seven scripts are allowed on the switch.
• The combined size of all script files on the switch cannot exceed 2 MB.
• The maximum number of configuration file command lines is 2000.

You can type single-line annotations in the configuration file to improve 

script readability. The exclamation point (!) character flags the beginning of a 

comment. The comment flag character can begin anywhere within a single 

line, and all input following this character to the end of the line is ignored. 

Any line in the file that begins with the “!” character is recognized as a 

comment line and ignored by the parser. 
The following example shows annotations within a file (commands are bold):
