Configuration Scripting Commands

Configuration Scripting allows you to generate text-formatted script files representing the current configuration of a system. You can upload these configuration script files to a PC or UNIX system and edit them. Then, you can download the edited files to the system and apply the new configuration. You can apply configuration scripts to one or more switches with no or minor modifications.

Use the show running-config command to capture the running configuration into a script. Use thecopy command to transfer the configuration script to or from the switch.

Use the showcommand to view the configuration stored in the startup-config, backup-config, or factory-defaults file.

You should use scripts on systems with default configuration; however, you are not prevented from applying scripts on systems with non-default configurations.

Scripts must conform to the following rules:

• Script files are not distributed across the stack, and only live in the unit that is the master unit at the time of the file download.
• The file extension must be “.scr”.
• A maximum of ten scripts are allowed on the switch.
• The combined size of all script files on the switch cannot exceed 2048 KB.
• The maximum number of configuration file command lines is 2000.

You can type single-line annotations at the command prompt to use when you write test or configuration scripts to improve script readability. The exclamation point (!) character flags the beginning of a comment, and can begin a word anywhere on the command line, and all input following this character is ignored. Any command line that begins with the “!” character is recognized as a comment line and ignored by the parser.

The following lines show an example of a script:

! Script file for displaying management access
show telnet !Displays the information about remote connections
! Display information about direct connections
show serial
! End of the script file!

Note

To specify a blank password for a user in the configuration script, you must specify it as a space within quotes. For example, to change the password for user jane from a blank password to hello, the script entry is as follows:

users passwd jane
" "
hello 
hello
