Please forgive organizational or formatting errors – this is my first Github repository. Please let me know if you have any tips or suggestions for improvement.
Please be aware that the code is UNFINISHED and still needs thorough testing and troubleshooting. USE AT YOUR OWN RISK. Always test code in a proper testbed and away from production devices. Follow proper change control procedures before deploying to production networks. I take no responsibility for any use of this code or any of its alterations.
Start this script by saving ‘main.py’ and ‘cdp_parse_functions.py’ into the same directory, then running ‘main.py.’
Enter SSH credentials, enter a ‘seed’ device to start CDP crawling from, and wait. There is also an SSH ‘test’ device you must enter – this simply tests your SSH credentials before kicking off the rest of the script.
‘main.py’ will reference functions from ‘cdp_parse_functions.py’ throughout the script
