linux下查看网卡信息的命令

　　rhel 内核版本信息：[html] view plaincopy[[email protected] ~]# uname -a Linux hvrhub 2.6.18-308.el5 #1 SMP Fri Jan 27 17:17:51 EST 2012 x86_64 x86_64 x86_64 GNU/Linux

　　查看网卡的驱动，制造商等信息：[html] view plaincopy[[email protected] ~]# kudzu --probe --class=network - class: NETWORK bus: PCI detached: 0 device: eth0 driver: r8169 ----------------& gt;这是驱动名称，下面的modinfo命令会用到该驱动名称。 desc: "Realtek Semiconductor Co., Ltd. RTL8101E/RTL8102E PCI Express Fast Ethernet controller" network.hwaddr: 20:cf:30:8f:5a:cf vendorId: 10ec deviceId: 8136 subVendorId: 1043 subDeviceId: 8347 pciType: 1 pcidom: 0 pcibus: 1 pcidev: 0 pcifn: 0 [[email protected] ~]#

　　下面是查看网卡的网速：[html] view plaincopy[[email protected] ~]# ethtool eth0 Settings for eth0: Supported ports: [ TP MII ] Supported link modes: 10baseT/Half 10baseT /Full 100baseT/Half 100baseT /Full Supports auto- negotiation: Yes Advertised link modes: 10baseT/Half 10baseT /Full 100baseT/Half 100baseT /Full Advertised auto-negotiation: Yes Speed: 100Mb /s ------------------------------------>网卡速度 Duplex: Full Port: MII

　　PHYAD: 0 Transceiver: internal Auto- negotiation: on Supports Wake-on: pumbg Wake- on: g Current message level: 0x00000033 (51) Link detected: yes

　　下面是查看网卡驱动的详细信息[html] view plaincopy[[email protected] ~]# modinfo r8169 filename: /lib /modules/2.6.18-308.el5/kernel/drivers/net /r8169.ko version: 2.3LK-1- NAPI license: GPL description: RealTek RTL- 8169 Gigabit Ethernet driver author: Realtek and the Linux r8169 crew < [email protected]> srcversion: 2F438BE7BC0FF431B08F6F4 alias: pci:v00000001d00008168sv*sd00002410bc*sc*i* alias: pci:v00001737d00001032sv*sd00000024bc*sc*i* alias: pci:v000016ECd00000116sv*sd*bc*sc*i* alias: pci:v00001259d0000C107sv*sd*bc*sc*i* alias: pci:v00001186d00004300sv*sd*bc*sc*i* alias: pci:v000010ECd00008169sv*sd*bc*sc*i* alias: pci:v000010ECd00008168sv*sd*bc*sc*i* alias: pci:v000010ECd00008167sv*sd*bc*sc*i* alias: pci:v000010ECd00008136sv*sd*bc*sc*i* alias: pci:v000010ECd00008129sv*sd*bc*sc*i* depends: mii vermagic: 2.6.18-308.el5 SMP mod_unload gcc- 4.1 parm: rx_copybreak:Copy breakpoint for copy-only-tiny- frames (int) parm: use_dac:Enable PCI DAC.

　　如下命令能看出来是不是集成网卡?---有待验证。 [html] view plaincopy[[email protected] ~]# dmidecode | sed -n '/net /,+5p' Type: Ethernet Status: Enabled Description: Onboard Ethernet -------------------> 这个意思是不是说这是集成网卡?有机会的话，弄个pci网卡上去，再执行此命令看看是啥输出。 Handle 0x0020, DMI type 11, 5 bytes OEM Strings

　　下面的命令也能看出网卡控制器的制造商信息。[html] view plaincopy[[email protected] ~]# lspci | grep Ethernet 01:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8101E/RTL8102E PCI Express Fast Ethernet controller (rev 02) [[email protected] ~]#
