Linux系统中查看mac地址命令有哪些

小编给大家分享一下Linux系统中查看mac地址命令有哪些，希望大家阅读完这篇文章之后都有所收获，下面让我们一起去探讨吧！

MAC(Media Access Control,介质访问控制)是用来定义网络设备的位置。用来表示互联网上每一个站点的标识符，采用十六进制数表示，共六个字节(48位)。

1：ifconfig命令查看网卡MAC地址

/sbin/ifconfig | grep HWaddr

或

/sbin/ifconfig | grep ether

有些Linux发行版本的MAC地址字段为HWaddr，有些Linux发行版本的MAC地址字段为ether。根据实际情况选择上面命令。

 [root@KerryDB ~]# ifconfig -a lo: flags=73 mtu 65536         inet 127.0.0.1  netmask 255.0.0.0         inet6 ::1  prefixlen 128  scopeid 0x10         loop  txqueuelen 1000  (Local Loopback)         RX packets 858  bytes 72251 (70.5 KiB)         RX errors 0  dropped 0  overruns 0  frame 0         TX packets 858  bytes 72251 (70.5 KiB)         TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0  p4p1: flags=4163 mtu 1500         inet 10.20.57.24  netmask 255.255.255.0  broadcast 10.20.57.255         inet6 fe80::b283:feff:fe55:32e5  prefixlen 64  scopeid 0x20         ether b0:83:fe:55:32:e5  txqueuelen 1000  (Ethernet)         RX packets 6637181  bytes 1536293500 (1.4 GiB)         RX errors 0  dropped 293652  overruns 0  frame 0         TX packets 4333535  bytes 1080300983 (1.0 GiB)         TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0

如果想只提取网卡MAC地址，可以使用下面命令(用具体的网卡名替换xxx)

ifconfig xxx | grep -o -E ‘([[:xdigit:]]{1,2}:){5}[[:xdigit:]]{1,2}’

 [root@KerryDB tmp]# ifconfig p4p1 | grep -o -E '([[:xdigit:]]{1,2}:){5}[[:xdigit:]]{1,2}' b0:83:fe:55:32:e5 [root@KerryDB tmp]#

方法2：/sys/class/net/xxx/address查看

根据网卡名调整，例如这里网卡名为ens160，如果网卡名为xxx,那么应该用/sys/class/net/xxx/address

 # more /sys/class/net/ens160/address 00:50:56:95:5c:16  # cat /sys/class/net/eth0/address 00:50:56:b3:81:f8

方法3：ip命令查看网卡MAC地址

 [root@KerryDB tmp]# ip link 1: lo:mtu 65536 qdisc noqueue state UNKNOWN mode DEFAULT group default qlen 1000     link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00 2: p4p1:mtu 1500 qdisc pfifo_fast state UP mode DEFAULT group default qlen 1000     link/ether b0:83:fe:55:32:e5 brd ff:ff:ff:ff:ff:ff [root@KerryDB tmp]# ip link show 1: lo:mtu 65536 qdisc noqueue state UNKNOWN mode DEFAULT group default qlen 1000     link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00 2: p4p1:mtu 1500 qdisc pfifo_fast state UP mode DEFAULT group default qlen 1000     link/ether b0:83:fe:55:32:e5 brd ff:ff:ff:ff:ff:ff [root@KerryDB tmp]# ip link show p4p1 2: p4p1:mtu 1500 qdisc pfifo_fast state UP mode DEFAULT group default qlen 1000     link/ether b0:83:fe:55:32:e5 brd ff:ff:ff:ff:ff:f [root@KerryDB tmp]# ip link show p4p1 | awk '/ether/ {print $2}'; b0:83:fe:55:32:e5

4：nmcli命令查看网卡MAC地址

 [root@KerryDB tmp]# nmcli device show p4p1 GENERAL.DEVICE:                         p4p1 GENERAL.TYPE:                           ethernet GENERAL.HWADDR:                         B0:83:FE:55:32:E5 GENERAL.MTU:                            1500 GENERAL.STATE:                          100 (connected) GENERAL.CONNECTION:                     p4p1 GENERAL.CON-PATH:                       /org/freedesktop/NetworkManager/ActiveConnection/1 WIRED-PROPERTIES.CARRIER:               on IP4.ADDRESS[1]:                         10.20.57.24/24 IP4.GATEWAY:                            10.20.57.1 IP4.ROUTE[1]:                           dst = 10.20.57.0/24, nh = 0.0.0.0, mt = 100 IP4.ROUTE[2]:                           dst = 0.0.0.0/0, nh = 10.20.57.1, mt = 100 IP6.ADDRESS[1]:                         fe80::b283:feff:fe55:32e5/64 IP6.GATEWAY:                            -- IP6.ROUTE[1]:                           dst = ff00::/8, nh = ::, mt = 256, table=255 IP6.ROUTE[2]:                           dst = fe80::/64, nh = ::, mt = 256 [root@KerryDB tmp]# nmcli device show p4p1 | grep -i hw GENERAL.HWADDR:                         B0:83:FE:55:32:E5

注意：这里根据实际的网卡名进行调整，如果网卡名为ens160，那么上面命令需要调整为

 # nmcli device show ens160 | grep -i hwaddr GENERAL.HWADDR:                         00:50:56:B4:00:94

5：dmesg命令查看网卡MAC地址

 [root@KerryDB tmp]#  dmesg | grep eth [    0.776155] r8169 0000:02:00.0 eth0: RTL8168g/8111g at 0xffffafbe80648000, b0:83:fe:55:32:e5, XID 0c000800 IRQ 27 [    0.776158] r8169 0000:02:00.0 eth0: jumbo features [frames: 9200 bytes, tx checksumming: ko]
