In the middle of a live VLAN readressing of a 200-node company, I encountered this gem. The ports just kept blinking on even after plugging out the cables. (HP aruba 24 port switch)

One turned off after a reboot.

That's normal.

The switch doesn't immediately detect that there is nothing plugged in. It keeps transmitting.

Edit: the lights are not even lit if you look closer
