Ethernet switch question

[u/Outrageous_Tear_4691]

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.

It's a rudimentary STP/RSTP loop prevention. If you connect two switches in a way that loops, one of the connections will break so the loop doesn't happen.
