Example code for various NetDevOps demos

We'll explain all the details as the demo goes on, but let's get setup to run these demos.

1. You'll need a workstation with Python 3.6 or 3.7 installed and functional along with Git.

2. Clone down the code from GitHub and change into the directory for this demo.

   git clone https://github.com/EricThiel/netdevops_samples
   cd netdevops_samples

3. Create a Python 3 virtual environment, and install the requirements (pyATS and Genie)

   python3 -m venv venv
   source venv/bin/activate
   pip install -r requirements.txt 
   

4. Create the "normal" profile for the network. This command can take up to 4 minutes to complete. You'll get a progress bar showing status as it runs.

   genie learn config routing --testbed-file lab1.yaml --output tests/normal

   • What this command is doing is giving Genie a baseline from which you can look for differences when something goes wrong.

5. After a failure, re-run to capture new state:

   genie learn config routing --testbed-file lab1.yaml --output tests/out1

6. Then, run a genie diff to find what has changed:

   genie diff tests/normal tests/out1 --output diff1

7. You may review the results within the diff1 folder in text files per parser and device.
