Forbidden LAN Cable Loop

Today, apparently during class, someone connected the wired LAN ports in the classroom to each other with a LAN cable, and a staff member from the IT center came flying in with a vibe like 'absolutely forbidden.'

A network switch is shown with a LAN cable connecting its own ports in a loop. The joke is that someone apparently created a forbidden classroom network configuration, prompting an IT staff member to react as if a serious technical violation had occurred. It is sent as a reaction to suspicious, cursed, or technically wrong setups. EN: A network switch is shown with a LAN cable connecting its own ports in a loop.
