I don't know whitch was the source interface, i have lot of SVI and ethernet 
interfaces so i think i can't do this monitoring :(
This incident happened now so first simply, and since then not. I saw nothing on 
  my MRTG graphs (for example: big incomming packets or other interesting 
things...).

I'll try this MLS command.

Thank You!
