I have a MS220-8P that has been unplugged for a while and when trunked back to the distro Meraki switch, it displays link lights, but the status light stays red and its web GUI continues to indicate it's down. The odd thing is, when looking at the distro switch, the port is green and indicates it can see the MS220 that's connected even showing traffic sent and received between it and the distant end switch. Is there any reason why the MS220 that is connected wouldn't display as connected? I'm also seeing STP errors from the distro switch on the current port for the MS220. Could this be caused by a bad SFP? Any ideas would be appreciated!
