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!
