如何使用命令查看網卡的MAC地址呢？下面總結一下查看網卡MAC地址的方式。html

1：ifconfig命令查看網卡MAC地址git

/sbin/ifconfig | grep HWaddrapp

或oop

/sbin/ifconfig | grep etherspa

有些Linux發行版本的MAC地址字段爲HWaddr，有些Linux發行版本的MAC地址字段爲ether。根據實際狀況選擇上面命令。code

 
  [root@KerryDB ~]# ifconfig -a 
  lo: flags=73<UP,LOOPBACK,RUNNING>  mtu 65536 
          inet 127.0.0.1  netmask 255.0.0.0 
          inet6 ::1  prefixlen 128  scopeid 0x10<host> 
          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<UP,BROADCAST,RUNNING,MULTICAST>  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<link> 
          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 
 

若是想只提取網卡MAC地址，可使用下面命令(用具體的網卡名替換xxx)orm

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

 
  [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ip

根據網卡名調整，例如這裏網卡名爲ens160，若是網卡名爲xxx,那麼應該用/sys/class/net/xxx/addressci

 
  # 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命令查看網卡MAC地址

 
  [root@KerryDB tmp]# ip link 
  1: lo: <LOOPBACK,UP,LOWER_UP> 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: <BROADCAST,MULTICAST,UP,LOWER_UP> 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: <LOOPBACK,UP,LOWER_UP> 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: <BROADCAST,MULTICAST,UP,LOWER_UP> 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: <BROADCAST,MULTICAST,UP,LOWER_UP> 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命令查看網卡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：這裏根據實際的網卡名進行調整，若是網卡名爲ens160，那麼上面命令須要調整爲

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

5：dmesg命令查看網卡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]
