如何使用MST工具查看Mellanox網(wǎng)卡端口狀態(tài)與光模塊信息-摩泰光電

1、MFT工具介紹

MFT，即Mellanox/NVIDIA Firmware Tools，是一套固件管理工具，用于查詢固件信息、固件升級等，含mst、mlxburn、flint、Debug utilities 4個子工具，具體功能參考NVIDIA官方資料：

表1 NVIDIA MFT描述

NVIDIA Firmware Tools (MFT) The MFT package is a set of firmware management tools used to: · Generate a standard or customized NVIDIA firmware image Querying for firmware information · Burn a firmware image The following is a list of the available tools in MFT, together with a brief description of what each tool performs.
MFT Tools
Tool	Description
mst	This tool provides the following functions: * Starts/stops the register access driver * Lists the available mst devices
mlxburn	This tool provides the following functions: * Generation of a standard or customized NVIDIA firmware image for burning (in binary or.mlx format) * Burning an image to the Flash/EEPROM attached to a NVIDIA HCA or switch device * Displaying the VPD (Vital Product Data)of an NVIDIA network adapter
flint	This tool burns a firmware binary image or an expansion ROM image to the Flash device of a NVIDIA network adapter/gateway/switch device.It includes query functions to the burnt firmware image and to the binary image file.
Debug Utilities	A set of debug utilities(e.g, itrace, fwtrace, mlxtrace, mlxdump, mstdump, mlxmcg, wqdump, mcra, mlxi2c, i2c, mget_temp, and pckt_drop)

2、MFT工具下載與安裝

Mellanox/NVIDIA官網(wǎng)下載MFT工具安裝包,本文以linux系統(tǒng)下mft-4.22.1-307-x86_64-rpm.tgz為例。安裝包下載網(wǎng)址：https://network.nvidia.com/products/adapter-software/firmware-tools/

a.終端對壓縮文件進行解壓，執(zhí)行命令： tar -zxf mft-4.22.1-307-x86_64-rpm.tgz

b.終端進入解壓縮文件并進行安裝，依次執(zhí)行命令：

cd mft-4.22.1-307-x86_64-rpm

./install.sh

c.啟動MFT，運行MST，執(zhí)行命令： mst start

3、MST工具讀取端口狀態(tài)與光模塊信息

執(zhí)行命令“mlxlink -d device -m ” ，查看接口信息，含接口狀態(tài)、接口配置、支持的速率、故障排除、光模塊識別、光模塊DOM信息等。

說明：device 為模塊所在接口的網(wǎng)絡地址，可以執(zhí)行命令“lspci” 進行查看。

摩泰光電提供的光模塊產(chǎn)品可用于Mellanox網(wǎng)卡/交換機，歡迎大家選購。
