Hi!
I bought four used MCX311A-XCAT.
Two of them are “made in israel”, the others are “made in china”.
If I query the chinese nic both reports
Description: Node Port1 Port2 Sys image
GUIDs: ffffffffffffffff ffffffffffffffff ffffffffffffffff ffffffffffffffff
instead with the israelis those fields are correctly populated.
All nics are reporting
PSID: MT_1170110023
so I updated the firmware at latest release 2.42.5000 from mellanox site.
All nics seems work properly with iperf3 test/benchmark and with windows SMB and linux samba and esxi 6.0U3 and esxi 6.5U2.
How to set proper/suitable GUIDs ??
Thank you in advance 😊
Best Regards from Rome

Hello Andrea,
The GUIDs can be changed using MFT (Mellanox firmware tool), that can be downloaded from here according to your OS:
http://www.mellanox.com/page/management_tools
Follow this guide:
https://docs.mellanox.com/display/MFTV4120/Setting+GUIDs+and+MACs
GUID is a unique identifier for each device so you should use the GUID that is written on the label that is attached to the adapter.
Best Regards.
Hi Viki,
I have rechecked all nics and seems those with “correct” GUIDs have the same GUIDs (!!).
On all MCX311A nics I have, there is a sticker with the mac address, but no GUIDs.
Instead on CX354A pcb I found both the mac address and guids on sticker, but again no guids on MCX311A sticker.
Best Regards From Rome🙂
