Abstract

A CLI command script template management system, tool, and human machine interface for script-based configuration management, service provisioning, operations and maintenance is provided. The system includes a CLI command dictionary repository, and means for loading a CLI command dictionary at run-time. Methods provide for obtaining a CLI command specification compatible with the CLI command set version currently deployed on the managed entity. The managed entity'"'"'s help functionality is invoked and the output is captured and parsed to discover the CLI commands set currently deployed on the managed entity. Advantages are derived from enabling operations management personnel to create CLI script templates easily for any active managed entity deployed in a managed communications network, based on the vendor and model specific network node CLI command set software release currently installed thereon.
