Issue

3090162

Description: The PCIe Error Injection feature is not supported due to a security limitation.

Workaround: N/A

Keywords: PCI Error Injection

Discovered in Version: 4.22.0

3446066

Description: When using ConnectX-7 and later cards, the link should be fully down (not in polling state) for the loopback configuration can be applied.

Workaround: N/A

Keywords: mlxlink

Discovered in Version: 4.23.0

3352983

Description: mlxfwreset does not work on mlnx-os/sonic/cumulus.

Workaround: N/A

Keywords: mlxfwreset

Discovered in Version: 4.23.0

3418112

Description: Loading a new firmware may require running mlxfwreset, and in some cases rebooting or initiating a power-cycle.

Workaround: N/A

Keywords: mlxfwreset

Discovered in Version: 4.24.0

3314750

Description: When entering link speed values, you can specify a single value (i.e "HDR") or a list of values separated by commas (i.e "HDR, FDR, SDE"). In the current MFTshell version, the autocomplete feature suggesting possible values, only works for the first value in a list of values separated by commas.

Additionally, the autocompletion list includes all possible speeds. Some of them may not be supported by the device. Once the command is fired, you will be notified in case the selected speed is not supported.

Affected shell commands are:

port speed

port autonegotiation on speed

port autonegotiation off speed

Any inconvenience caused by these limitations will be addressed in future MFTshell updates.

Workaround: When entering a link speed, you may press the key first. This will provide you with all possible values. You can then select the desired link speed value, copy and paste it into the command prompt, and type a comma (,) to select the next speed. Repeat the process to form a list of all desired link speed values separated by commas.

Once the command is fired, the underlying MFT tool will inform you if the selected speed is not supported by the device.

In addition, the help context for the affected shell commands includes detailed explanations of the available options.

Description: The mlxfwreset tool does not support Cedar system.

Workaround: N/A

Keywords: mlxfwreset, Cedar, ConnectX-7

Discovered in Version: 4.23.0

3188577

Description: Some firmware scratchpad registers have been moved to a different location. Therefore, if you use your own utility to dump mstdumps, you must update your CSV file with the latest CSV, CSV2 files that are included in the MFT package.

Otherwise, the mstdumps device will not retrieve the firmware version, and the FAEs will not be able to use NVIDIA internal tools to debug the error.

Workaround: N/A

Keywords: CSV, mstdump

Discovered in Version: 4.18.0

2838222

Description: mlxfwreset is not supported on kernel 3.10.0-1062.el7.x86_64 due to a kernel bug that leads to 'rescan' PCI operation to take a few minutes.

Workaround: N/A

Keywords: mlxfwreset

Discovered in Version: 4.18.0

Description: Burning firmware using DMA might fail on virtual FreeBSD machines.

Workaround: N/A

Keywords: Firmware burning, DMA, FreeBS, VM

Discovered in Version: 4.17.0

2484780

Description: Configuring TX/RX_rate to 200GbE in test mode fails.

Workaround: To work with the new speeds specify the number of lanes as shown below:

  • 100G_1X/200G_2X/400G_4X/800G_8X for NDR speeds

  • 50G_1X/100G_2X/200G_4X/400G_4X for HDR speeds

Keywords: 200GbE, Tx/Rx

Discovered in Version: 4.17.0

2392334

Description: Using the MFT with the --with-pcap option to install stedump utility requires the following third-party dependencies:

  • Libraries and header files for the libpcap library

  • Libraries and header files for Python development library

  • Package Installer for Python (PIP) available

Workaround: To install the third-party dependencies, perform the following:

  1. Install libpcap-devel or libpcap-dev on Debian-based distributions.

  2. Install python3-devel or python3-dev on Debian-based distributions.

  3. Bootstrap the PIP installer in one of the following ways:
