Hello WChan5,


Thank you for posting in Intel Ethernet Communities. 


I hope you're having a wonderful day. For us to further check the issue, please provide the following details.


  1. What is your OS?
  2. Are you using an onboard X550-T2?
  3. If you are using a PCIe X550-T2 can you send a picture on both sides for us to check the markings?


If you have questions, please let us know. In case we do not hear from you, we will make a follow up after 3 workings days. Thank you.

Hello WChan5,

 

I hope you're having a wonderful day. Before we close this thread, let me also add that Modifying the MTU size of Intel® Network Adapter is dependent on the connecting equipment configuration. Please contact the equipment provider to confirm if matching the MTU frame size is required.

 

If you have questions, please let us know. In case we do not hear from you, we will make a follow up after 3 workings days. Thank you.
