mlxconfig – Changing Device Configuration Tool

The mlxconfig tool allows the user to change some of the device configurations without reburning the firmware. The configuration is kept after reset.

By default, mlxconfig shows the configurations that will be loaded in the next boot. For 5th generation devices, it is also possible to query the default configurations and the configurations that are used by the current running firmware.

  • OFED/WinOF driver to be installed and enabled (for ConnectX-3 and ConnectX-3 Pro)

  • Access to the device through the PCI interface (pciconf/pci_cr)

  • For the adapter cards below, the following firmware versions are required:

    • ConnectX®-3/ConnectX-3 Pro: v2.31.5000 or above

    • Connect-IB®: v10.10.6000 or above

  • Supported devices:

    • Adapter cards: ConnectX-3/ConnectX-3 Pro/Connect-IB/ConnectX-4/ConnectX-4 Lx/ConnectX-5/ConnectX-5 Ex/ConnectX-6/ConnectX-6 Dx/ConnectX-6 Lx/ConnectX-7/NVIDIA BlueField®/NVIDIA BlueField-2/NVIDIA BlueField-3

    • Switches: Switch-IB/Switch-IB 2/Spectrum™/Spectrum-2/Spectrum-3/Spectrum-4/Quantum/Quantum-2

  • Changing device configurations enabled.

Warning

For changes after a successful configuration to take effect, reboot the system.
