This looks like port flapping. There can be a few causes of that. Among them are bad cabling and a defective NIC on either side of the cable.

  • Thank you in a little while i test with another cable. Do you think the problem may come from too many connection requests? – Simone Melloni Sep 04 '13 at 10:59
  • I can't imagine why that might cause a hardware failure, no. Keep in mind that this is usually a cable, but sometimes a NIC too. – Falcon Momot Sep 04 '13 at 10:59
