## Overview

This repository is a Cisco networking reference, not an executable application: its principal workflow is a reader consulting the cheat sheet for configuration and troubleshooting guidance. The README documents switching, routing, network services, device management, CLI usage, and packet structures. The tree contains only README.md, so all documented capabilities point to that file; no runtime calls or data transfers can be inferred.

Main entry points: [`README.md`](https://github.com/ronjaponja/ccna-cheat-sheet/blob/master/README.md) (CCNA Cheat Sheet)
