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.

    Actually it’s by design! Right side is for the lower ports, that’s why there’s the number with an arrow above it.

      Yeah, which is how we know that 5 isn’t patched into a machine, (likely goes to patch panel, then through the walls to an office/cubical with no machine connected to that port.)… Often means someone was fired and not replaced, or else the patch would be swapped to another place if they replaced the user and placed them elsewhere.

      (Doesn’t have to be that, could be other things of course, like a laptop someone took home, a dead VoIP phone… A disconnected media station, etc)
