I recently purchases my first RouterOS-based product, and I'm experimenting with the settings. Often, after I've configured something it will show an "I" next to it in both the console and the GUI. Tooltip in the GUI and legend in the console say it means "invalid". I can't seem to find a place in the GUI or console which elaborates on why any given setting is invalid. Where can I get that kind of information?
I'm intentionally not providing my current configuration because I don't want people getting tunnel-vision. I am asking a very general question because I need the general answer. It's important for me to be able to do at least a little troubleshooting on my own rather than needing to make a forum post for every issue.
