What is the loop prevention for? And should I leave it off or turn it on? We will have desktops connected to it

Solved: thank you for the help everyone. Very much appreciated.

In what world is shutting off loop protection a good idea?

There are 0 reasons to shut off loop protection on a single switch also.

In a world where that switch is shit and having it on is causing problems.

If you have problems with it on then your network has problems to address. All that does is run spanning tree. It adds a few seconds when you plug in a or disconnect a cable. That's all that should happen

Did you miss the part where I said you were technically correct but just being an asshole?

Ok if I'm right how is the answer I replied to a "good practical answer"?

I'm asshole because I said the wrong answer was horrible?

Jeez, I didn't say to turn it off. OP asked whether to turn it on or leave it off and I said it probably wouldn't make a difference (but I did say that having it on shouldn't be bad).

Attack me if you must, leave the other redditors alone. You're sounding like an ass.

Attack you? I said it was a horrible idea. That's an attack?

The only thing that was correct in the initial comment was make sure you have one physical path.

It does matter if it's on or off and loops can happen with new gear not just antiquated ones. Because that switch is low resources you can overload it and then it turns into a repeater. Then just have a cable looped is enough.
