Linux使用ifconfig或lspci获取网卡信息

ifconfig和lspci是Linux用来获取网卡最常用的两个命令。

ifconfig获取网卡

使用ifconfig可以获取到多个设备和设备状态、信息。

示例：

[cc@localhost~]$ ifconfig
      eth0      Link encap:Ethernet  HWaddr 00:0C:29:A4:5A:BF  
          inet addr:192.168.1.160  Bcast:192.168.1.255  Mask:255.255.255.0
          inet6 addr: fe80::20c:29ff:fea4:5abf/64 Scope:Link
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
          RX packets:1650 errors:0 dropped:0 overruns:0 frame:0
          TX packets:112 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:1000 
          RX bytes:134000 (130.8 KiB)  TX bytes:12228 (11.9 KiB)
     eth1      Link encap:Ethernet  HWaddr 00:0C:29:A4:5A:C9  
          inet addr:192.168.1.161  Bcast:192.168.1.255  Mask:255.255.255.0
          inet6 addr: fe80::20c:29ff:fea4:5ac9/64 Scope:Link
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
          RX packets:1618 errors:0 dropped:0 overruns:0 frame:0
          TX packets:88 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:1000 
          RX bytes:125909 (122.9 KiB)  TX bytes:9320 (9.1 KiB)
     lo        Link encap:Local Loopback  
          inet addr:127.0.0.1  Mask:255.0.0.0
          inet6 addr: ::1/128 Scope:Host
          UP LOOPBACK RUNNING  MTU:16436  Metric:1
          RX packets:182 errors:0 dropped:0 overruns:0 frame:0
          TX packets:182 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:0 
          RX bytes:10340 (10.0 KiB)  TX bytes:10340 (10.0 KiB)

lspci获取网卡信息

lsci可列出每个pci总线上的设备，通过grep过滤后可得到网卡设备列表。

[cc@localhost~]$ lspci |grep -i 'eth'

  02:06.0 Ethernet controller: Intel Corporation 82545EM Gigabit Ethernet Controller (Copper) (rev 01)
