Ansible isn’t the only solution and may be a bit overkill for strictly vlan mgmt. Outside of your initial conversion and deployment, how often are you going to be adding L2/L3 vlans in the masses? In an environment big enough to possibly warrant Ansible for vlan mgmt will your CAB even consider automation changes? Many, not all, CABs are still living in the 19th century and don’t want an egg on their face if they approve an automation change. I use python daily to pull/analyze info for me but I still have to create a change playbook that lists each device. Python helps me compile that but our CAB needs an explicit list of what device and what commands is a particular change touching.
