查看“Ifconfig”的源代码

=简介=
ifconfig是用于网络接口配置的系统管理实用程序。

=安装此工具到开发板上=
ifconfig是默认安装的，可以与所有STM32MPU嵌入式软件包一起使用。

 Board $> which ifconfig | xargs ls -la
 /sbin/ifconfig -> /bin/busybox.nosuid

=开始使用=
==列出所有网络接口==
 Board $> ifconfig  -a
==列出可用的网络接口==
 Board $> ifconfig 
<syntaxhighlight lang="bash">

==禁用网络接口==
*例如，对eth0接口进行如下操作
 Board $> ifconfig eth0 down
==启用网络接口（如果不可用）==
*例如，对eth0进行如下操作
 Board $> ifconfig eth0 up
==为网络接口指定IP地址==
*请按以下步骤为eth0分配 192.168.1.12 地址
 Board $> ifconfig eth0  192.168.1.12
