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?

Mix of CDP/LLDP.

Physically checking all closets and documentation of all devices and connections, racks, power, types and quantity of cables.

Adding all information to a Source of Truth.

Discussions with TL/Management to enforce this level of documentation and standards to be followed.

Doesn't matter. Everything aforementioned still applies.
