Hello, I met a problem when I set the trust-mode for the ConnectX3-Pro 40GbE NIC.
The system information follows:

It’s the first time that I have met this problem. So I don’t know what to do.
What does this tip mean? Is the system version the main cause?
Waiting for your help.
Thanks.

Hi,
What is your current system ? Distribution / Kernel
ConnectX-3 Pro
FW version ?
PSID ?
Can you try with the latest Mellanox OFED 4.4 ?
Maybe the p4p1 is not the mellanox interface ?
Maybe it is not configured as ethernet interface ?
Please check
Marc
Hi, Marc.
The system information is as following:
The RNIC information is as following:
And I upgrade the OFED to 4.4, the result is the same.
I have checked the interface parameter and it’s right.
Thanks.

Hi,
After a first check on my card ConnectX-3, I got the same behavior
It seems to be supported only from ConnectX-4 and above.
If you want me to investigate it more, please open a ticket.
mlnx_qos -i ens6
Buffers commands are not supported on your system

Hi
Can you show me ibdev2netdev output
Can u also try
mlnx_qos -i
Thanks
Marc
Hi, Marc.
I installed MLNX_OFED_LINUX-4.1-1.0.2.0 on my server and used the provided tool “mlnx_qos” to set the trust mode for Connect-X 3 Pro.
The command is “mlnx_qos -i p4p1 --trust=dscp”.
Then the result is “Priority trust mode is not supported on your system”.
Thanks
Hi, Marc
Ah…
Sorry, after upgrading OFED to 4.4, the trust mode can be set on RNIC.
But there is another error message: “Buffers commands are not supported on your system”.
Thanks.

Hi,
Can you make the try to modify the buffer size and send me the output.
ibdev2devnet also , please.
Marc
Hi, Marc
The result is as following:
It seems that the buffer commands is a new feature for PFC in OFED 4.4.
I checked the OFED 4.3 and didn’t see this option for mlnx_qos.
Thanks.
