Network Automation Scripts

This repository contains a collection of Python scripts for network automation tasks. These scripts utilize the scrapli library for SSH connections, networkx for network topology visualization, and various other libraries for parsing and processing data from network devices.

Input hosts file template is added to the repository.

Prerequisites

Make sure you have Python 3 installed. You can install the required libraries using the provided requirements.txt file:

pip install -r requirements.txt

Script Descriptions

1. GetDevices.py

This script fetches CDP/LLDP neighbor information from network devices specified in a CSV file and builds a network topology. It then visualizes the topology using networkx and matplotlib.

Usage:

1. Modify the CSV file hosts.csv to include the details of network devices.
2. Run the script:

   python GetDevices.py
   

2. GetHostnames.py

This script connects to network devices, retrieves the hostname, and updates the hostname in the input CSV file.

Usage:

1. Modify the CSV file hosts.csv to include the details of network devices.
2. Run the script:

   python GetHostnames.py
   

3. MacLookup.py

This script parses MAC address table information from network devices' show commands and saves the results in a CSV file.

Usage:

1. Place show command output files in the output directory.
2. Run the script:

   python MacLookup.py
   

4. RemoveFiles.py

This script iterates over directories and deletes files with "_diff.txt" in their names.

Usage:

1. Modify the directory_path variable in the script if needed.
2. Run the script:

   python RemoveFiles.py
   

5. RunDiff.py

This script compares two directories containing files and generates diff files for differences.

Usage:

1. Modify the main_directory1 and main_directory2 variables in the script.
2. Run the script:

   python RunnDiff.py
   

6. SaveInfo.py

This script connects to network devices, executes commands, and saves the command output in files.

Usage:

1. Modify the CSV file hosts.csv to include the details of network devices.
2. Place the commands to be executed in the commands.csv file.
3. Run the script:

   python SaveInfo.py
   

7. SaveVersion.py

This script parses version information from network devices' show version commands and saves the results in a CSV file.

Usage:

1. Modify the directory_path variable in the script
2. Place show command output files in the directory_path directory
3. Run the script:

   python SaveVersion.py
