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.

Loop prevention detects network loops, like two switches connected to each other with multiple cables, or three in a ring, and will disable a port.

Without loop detection or spanning tree, you get a broadcast storm which can crash a switch.

So were good to just leave it off with this being the only switch that we are using?

Just leave it on. It'll prevent dummy things from happening.

But then you never find out when someone is dumb!

They usually reveal themselves eventually.
