API Reference

ncdiff module

ncdiff module defines a set of classes that calculate diff of two configs, and predict config when a diff is applied on a config. A config is the payload of a Netconf get-config reply, and a diff is the payload of a edit-config message.

• ncdiff.RunningConfigDiff class
• ncdiff.ModelDownloader class
• ncdiff.ModelCompiler class
