I like it !!! Motion in the Ocean ... In my world of 6000 plus metro fiber links tracking the change in light levels over time is a basic part of trying to be pro-active about degradation of the fiber links. It also plays an important part in the restoration process as NOC can compare before and after splice to an graph that gets updated just like any other interface stats... Really dont care about anything but transmit and receive levels in db.... Thanks Extreme Team for looking into this as a future feature
