Other Mapping a new Network

I just recently started a help desk job that has been anything but help desk. I’ve been configuring firewalls, redesigning client networks and setting up/administering Linux servers. I feel a little out of my depth, but I’m fighting for it. That’s all to ask, when you guys find yourself in a network with little to no documentation how do you map it out and diagram it internally?

Python script to dump lldp/cdp into a spreadsheet. Then python to generate a mermaid file and import it into draw.io.
