Linux MAC地址查看命令详解

在Linux系统中，查看MAC地址是一项常见操作，有助于网络配置、故障排查等工作,以下是几种常用的查看MAC地址的命令及详细介绍：

使用ifconfig命令

基本用法

ifconfig是一个传统的网络配置命令，尽管在一些新的Linux发行版中可能不再预装，但它仍然被广泛使用，要查看所有网络接口的MAC地址,可以使用以下命令：

ifconfig -a

该命令会显示系统中所有网络接口的详细信息，包括接口名称、IP地址、子网掩码、MAC地址等。

查看特定接口的MAC地址

如果只想查看特定网络接口（如eth0或wlan0）的MAC地址,可以使用以下命令：

ifconfig eth0

或者

ifconfig wlan0

在输出信息中，HWaddr字段后面的就是该接口的MAC地址。

示例输出

eth0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1500
        inet 192.168.1.100  netmask 255.255.255.0  broadcast 192.168.1.255
        inet6 fe80::20c:29ff:fea7:b3c1  prefixlen 64  scopeid 0x20<link>
        ether 00:0c:29:0a:7b:3c  txqueuelen 1000  (Ethernet)
        RX packets 12345  bytes 1234567 (1.2 MB)
        RX errors 0  dropped 0  overruns 0  frame 0
        TX packets 1234  bytes 123456 (120.5 KB)
        TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0

在上述输出中，ether 00:0c:29:0a:7b:3c即为eth0接口的MAC地址。

使用ip命令

基本用法

ip命令是一个强大的网络配置工具，可以用来查看网络接口的各种信息，包括MAC地址，要查看所有网络接口的MAC地址,可以使用以下命令：

ip addr show

或者简写为：

ip a

该命令会列出系统中所有网络接口的IP地址、子网掩码、广播地址以及MAC地址等信息。

查看特定接口的MAC地址

如果只想查看特定网络接口的MAC地址,可以在命令后加上接口名称，

ip addr show eth0

或者

ip a show wlan0

在输出信息中，link/ether字段后面的就是该接口的MAC地址。

示例输出

2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP group default qlen 1000
    link/ether 00:0c:29:0a:7b:3c brd ff:ff:ff:ff:ff:ff
    inet 192.168.1.100/24 brd 192.168.1.255 scope global dynamic eth0
       valid_lft 86400sec preferred_lft 86400sec
    inet6 fe80::20c:29ff:fea7:b3c1/64 scope link 
       valid_lft forever preferred_lft forever

在上述输出中，link/ether 00:0c:29:0a:7b:3c即为eth0接口的MAC地址。

使用nmcli命令（适用于安装了NetworkManager的系统）

基本用法

如果你的系统上安装了NetworkManager，可以使用nmcli命令来查看网络接口信息，要查看所有网络接口的MAC地址,可以使用以下命令：

nmcli device status

该命令会显示系统中所有网络设备的状态、连接状态、IP地址以及MAC地址等信息。

查看特定接口的MAC地址

如果只想查看特定网络接口的MAC地址,可以在命令后加上设备名称，

nmcli device show eth0

或者

nmcli device show wlan0

在输出信息中，GENERAL.HWADDR字段后面的就是该接口的MAC地址。

示例输出
