xpost with /r/networking

Years ago circa 2014 I used some software for making network diagrams that were dynamically generated by manually entering network inventory information into some software. You could then manipulate the diagram and label it accordingly to produce cable schedules, network topology diagrams, interconnectivity diagrams etc.

Here's a diagram output (some parts redacted).

Does anybody recognise this software at all? Killing me trying to remember what it was called. I believe there was a "free for home use" and a commercial variant, but I could be wrong.

EDIT: Looking for either this or recommendations of software that can build auto-generated diagrams very easily. I already use Visio for other things!
