All ill say is ROS script is a huge PITA.
So, making a script that takes an object of vlan/port assignments, and running the required commands to ensure the config of the mikrotik matches the declared vlan/port assignments.
The besy way ive seen to build/manage them is to use a compile step to go from some sane declarative config in order to build the actual ROS script to make the changes.
I just havent got round to making that a thing.
I hope they are working on a native python API, so i can script in a sane language, and run it directly on the mikrotik.
Config files are easy to import/export/edit/read, tho.
It does mean you have to reset to default when you update a config file (or configure the device live, then export the config)
