Thanks alot Peter As I said, I use Cacti as my frontend, and it is configured to graph all of our interfaces, so I don't have the option to change my frontend now. Also, I used unknaszer in my cfg, I guess it will make the NaN as Zero, hence overcoming the NaN phenomenon ( I wish, but it seems not to work !!) Now let the question be, what NaN do exactly, when using RRD with MRTG ???
