It seems like shortly after NPM introduced the UnPlugged setting (so a device doesn't give a false indication of a sub-component problem when ports are unused), I upgraded UDT from 1 to 2 and now my maps once again indicate a sub-component problems; but when you drill into the maps/devices, there's nothing wrong. My guess is UDT is now identifying unused ports as Down (red). On the Node Details page, the unused ports are not shown in red under the UDT section, they are gray; but nothing else changed except upgrading to UDT 2.
Has anyone else experienced this? Or do I have a bug in my system?
