No traffic the server keep going down on my peer to peer network (unable change link status to up)

[golfball1810]

I have two computers one computer I connect to FreeNAS admin panel (home computer) and the second computer is FreeNAS Plex server. I have a peer-to-peer connection between two computers with which I use for file sharing. After few hours of not using this connection to the FreeNas server, the link state goes from up to down. Is there a way to keep the link state to stay UP. Please note my intel x540-t2 10gbe 2 port ethernet card does not have Wake On Lan. The only way I can get link state to go back up is to delete the connection and reenter it again or restart the server. I tried many ifconfig commands with no success. I also added commands to the options box under the network port.

Check to see if the Yottamark on the card validates. There are a lot of fake X540 cards out there, and "not working right" is a typical symptom.

Check to make sure that you have adequate airflow over the card. A classic error is to take this card, designed for rackmount servers with significant back-to-front airflow forced over the PCI cards, and to put it in an ATX chassis with minimal to no airflow. This causes the card to slowly bake and eventually crash.
