I label both ends of the cable using the specialised Zip Ties, and mark the opposite end of the cable - doing it this way is great if you are trying to fault find if I go to an intermediate hub I can quickly find the cable I am looking to test,
The system was developed when I used to work a lot in industrial systems you would open a connection panel and see several hundred cable ends -
knowing what any cable connected to saves a lot of identification work
Of course in the electrical panels you would have every cable marked with a wire/cable reference - adding an "english" description save time checking through the design specs and or wiring diagrams
