Networking requires knowledge of the necessary configurations of the network devices belonging to them. The search for these configurations turns out to be a tedious and repetitive task due to the large number of existing configurations. Model-driven engineering (MDE) allows you to create solutions to this problem, automating these tasks. This document presents the development of two specific domain languages (DSL) based on MDE, one graphic: CNPGraph, and one textual: CNPText as a solution to the problem.
