在Windows操作系统中，通过命令提示符（cmd）可以轻松查看电脑的物理以太网卡信息。以下是一些常用的命令和步骤，帮助你获取所需的信息。
1. 使用ipconfig命令
ipconfig 是一个常用的命令，可以用来查看网络接口的配置信息。
步骤：
- 打开命令提示符。你可以通过在开始菜单搜索“cmd”并点击“命令提示符”来打开它。
- 在命令提示符窗口中，输入以下命令并按回车键：
ipconfig /all
这将显示所有网络接口的详细信息，包括物理以太网卡的MAC地址、IP地址、子网掩码、默认网关等。
输出示例：

2. 使用netsh命令
netsh 是一个强大的命令行工具，可以用来配置和管理网络设置。
步骤：
- 打开命令提示符。
- 输入以下命令并按回车键：
netsh interface show interface
这将显示所有网络接口的详细信息，包括物理以太网卡的MAC地址、IP地址、子网掩码、默认网关等。
