Changed to Ethernet using mlxconfig
FW version: 16.27.2008
I might have accidentally changed something due to which it starts linking at x8, it used to link at x16. Can you please let me know how can I force it to link at Gen4 speed or reset the NIC so it can be defaulted to factory settings and come up at gen4 (x16). I have also tried mlxfwreset and level3 and it still comes up at x8.
I had tried to look for a way to change/configure Pcie speed but could not find a procedure for that. Please point me to the correct post if it’s already been discussed.
What changes did you apply in the mlxconfig ?
can you provide the output of mlxconfig -d -e q
make sure that the PCIE slot is GEN 4
Are you able to resolve the issue ?
Please find the details attached.
The issue is still not resolved, I ahve not changed any settings intentionally that could force the NIC to come up at Gen3. It’s a Gen4 slot and it’s a Dell system R7515 EPYC 7542.
I have another CX-5 NIC and it comes up correctly in same system (in same slot) so I believe it has to do some config.
Can you open Support case at firstname.lastname@example.org for further debug ?
In addition, why you are applying changes in the below firmware parameters :
Can you revert back and check if the issue persist ?
I can try to revert these settings and give it a try.
Let me know if it’s working
