UBNT Infrastructure Part 7 – Core Cabling… a few changes

And we get to another issue that I had. It happened at 11 am around the second week of term, some of my core switches started dropping packets.

The start of this work took place in the lead up to the Christmas break. I had unpacked all the switches and configured them with generic settings like names, IP, VLANs, tagging etc. And on 8th of January, I would be installing the switches.

I was locked and loaded. And unprepared.

To answer that I should let you know how I got to use that solution. It is one thing to rattle off your current stack of software, I would rather show you how I came to that setup.
