Junos OS configuration commit scripts "Stylesheet language alternative syntax (SLAX)"

This feature enables you to use scripts that run at commit time to enforce custom configuration rules. If a configuration breaks the custom rules, the script can generate actions that the operating system software performs. Configuration commit scripts also enable you to create macros, which expand simplified custom aliases for frequently used configuration statements into standard configuration statements used by the device. Commit scripts are written inStylesheet Language Alternative syntaX (SLAX).
