Ethernet ports on that don't have anything plugged in to them

Why does it seem like I’m getting this issue while after changing to 6.41? I now how two routers that are doing this in the past couple weeks after upgrading.

Are they just junk, or is the software doing something it shouldn’t??

I too have seen this. It appears that the lights on the front of my rb3011 mirror each other on each switch. Items plugged into port 7 seem to blink port 2, port 8 blink both port 8 and 3.

Strange behavior.
