With default apt-get repo, i am able to install rdma-core. But with MLNX_OFED package, i am facing this issue.

The other issue - We purchased ConnectX-5 VPI adapter card (MCX556A-ECA_Ax). As it is VPI card, it should support both Infiniband and Ethernet. My network card is working fine with Infiniband but when I change it to Ethernet, the physical link status is always disabled. I have attached screenshot for your reference. Please help me in this matter.


It seems that the iwpmd service does not exist on your system.
Two things you can try:

  1. Try to download the latest LTS (23.10- version from: Linux InfiniBand Drivers
    And install it - see if that is installed successfully.
  2. If the above fails, I would try to install iwpmd manually with apt-get, and then run the MLNX_OFED installation again.

Regarding the second question - this could be related to cables perhaps.
Maybe the cable connected to the device port is an IB cable, therefore does not activate the link for Ethernet.
If MST is installed on the system, you can run:
mlxlink -d /dev/mst/xxxxx_pciconf0
To see the link information. Under “speed” you should see if the link is IB or ETH.
You can add the “-m” flag to get information on the specific module connected, including it’s Part Number, which you can search for online to get more details.

I hope this helps.
If you still have questions, please open a case at:, and it will be handled according to entitlement.
