Thanks for your answer. I have contact the DELL support. We have unselect this option but the still the same. After a lot of investigation we have try to set spanning-tree disable on the port of the switch.  This solution solve this packet error, but the tech don't explain me why the old PS (SAN1) doesn't have this error too. Thanks for your help Joe
