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
Andrea

Hi, thank you for your quick reply!!

You are right!
I downloaded the manual and the command is as you suggest.
My concern is about "the algorithm" to base guids configuration because in nic bios configuration dump (flint -d <device> dc), there is

gen_guids_from_mac = true

I don't know how to determine what guids to choose.
Any suggestions?
Thank you again :)
Andrea

edit: I have rechecked all nics and seems those with "correct" GUIDs have the same GUIDs !!
