Systems and methods are provided for generating an Internetworking Operating System (IOS) Command Line Interface (CLI) configuration model and a logical topology from an IOS CLI configuration base. The method includes representing structure and cross-CLI dependencies in a formal specification format, such as Extended Backus-Naur Form (EBNF), and translating the representation into a machine-processable structure and code referred to as the IOS CLI Dependency Tree (ICDT). The ICDT is the configuration model. The ICDT optionally may be manipulated to generate configuration models in other formats, such as Java classes or XSD (eXtensible markup language Schema Definition). The method further includes generating the logical topology from the ICDT.
