Systems and methods are provided for dynamic grammar augmentation for editing multiple network switch configuration files as a single file. The method includes identifying a first base grammar of a first network switch; identifying a second base grammar of a second network switch; identifying first and second patch grammars for the first and second network switches; generating an augmented grammar based on the first and second patch grammars and the first and second base grammars; identifying a first configuration file for the first network switch; identifying a second configuration file for the second network switch; generating a base merged configuration file, the base merged configuration file representing the first and second configuration files modified according to the augmented grammar.
