Hi,
I have a 3750X stack with two switches in the stack that have 24 ports. There are some ports on the switches that do not have the green link light indicator illuminated, however at the command prompt the same ports show up-up. The switches are running the version listed below. Is there something other then a hardware issue I should be looking at here?

I've had some issues out of my 3750 stack. Here's what I would try. Console in, sh int gix/x and make sure that that when you pull the cable the port shows down down rather than up up. If it still shows up up after the cable has been pulled, then make sure you are looking at the correct switch in the stack. I've often times got confused with which one I was looking at.........especially if I am remote. If you still show up up on the port and the cable is pulled then a reboot is warranted. The 3750 stack that we have is at our DR and is the core for that setup. We've had some funky stuff like that happen and it has had to be rebooted which fixes the problem usually..........sometimes a 2nd reboot has to be performed ?. BTW we're running.

What position is the mode indicator in ? Those lights can mean multiple things depending which position the mode indicator is in .
