    How to enable the MT4103(connectx-3 pro) physical port

    lane

      It is found that when configuring the adapter as RoCEv2 by “options mlx4_core roce_mode=0000:81:00.0-1,0000:84:00.0-1”, after OS rebooting, one MT4103 can not work well. But there is nothing wrong for another one with the same firmware.

       

      The port state always shows “Disabled" as below:

      # ibstat mlx4_1

      CA ‘mlx4_1’

        CA type: MT4103

        Number of ports: 1

        Firmware version: 2.42.5000

        Hardware version: 0

        Node GUID: 0xe41d2d030029ecb0

        System image GUID: 0xe41d2d030029ecb0

        Port 1:

        State: Down

        Physical state: Disabled

        Rate: 10

        Base lid: 0

        LMC: 0

        SM lid: 0

        Capability mask: 0x04010000

        Port GUID: 0xe61d2dfffe29ecb0

        Link layer: Ethernet

       

      And related ethnet interface’s link can not be detectable, but actually the cable is connected.

      # ethtool ens259

      Settings for ens259:

        Supported ports: [ FIBRE ]

        Supported link modes:   1000baseKX/Full

        Supported pause frame use: Symmetric Receive-only

        Supports auto-negotiation: No

        Advertised link modes:  1000baseKX/Full

        Advertised pause frame use: Symmetric

        Advertised auto-negotiation: No

        Speed: Unknown!

        Duplex: Unknown! (255)

        Port: FIBRE

        PHYAD: 0

        Transceiver: internal

        Auto-negotiation: off

        Supports Wake-on: d

        Wake-on: d

        Current message level: 0x00000014 (20)

               link ifdown

        Link detected: no

       

      I have tried OFED driver of MLNX_OFED_LINUX-4.4-1.0.0.0-rhel7.4-x86_64 and MLNX_OFED_LINUX-4.4-2.0.7.0-rhel7.4-x86_64. Neither can work.

       

      The switch is Dell 4048-on.

       

      So, what is the problem with one MT4103? How can I enable the physical port?
