篇首语:本文由小常识网(cha138.com)小编为大家整理,主要介绍了linux查看网卡信息 命令相关的知识,希望对你有一定的参考价值。

参考技术A

    ifconfig和lspci

    2.lspci |grep -i 'eth' 或 lspci | grep -i net命令

    3. 3.iwconfig  :用于查看无线网络,如果你设备上有无线网卡此时可用此命令来查看

    4.ethtool -p eth0

linux下查看网卡信息的命令

rhel 内核版本信息:

[root@hvrhub ~]# 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:

[root@hvrhub ~]# kudzu --probe --class=network
-
class: NETWORK
bus: PCI
detached: 0
device: eth0
driver: r8169 ---------------->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

subVendorId: 1043
subDeviceId: 8347
pciType: 1
pcidom:    0
pcibus:  1
pcidev:  0
pcifn:  0
[root@hvrhub ~]# 

下面是查看网卡的网速:

[root@hvrhub ~]# ethtool eth0
Settings for eth0:
        Supported ports: [ TP MII ]
        Supported link modes:   10baseT/Half 10baseT/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

[root@hvrhub ~]# modinfo r8169

如下命令能看出来是不是集成网卡?---有待验证。 

[root@hvrhub ~]# 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。

[root@hvrhub ~]# lspci | grep Ethernet
01:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8101E/RTL8102E PCI Express Fast Ethernet controller (rev 02)
[root@hvrhub ~]# 

 

查看网卡网速的另外一个命令:

[root@testb .vnc]# ethtool -i eth0
driver: r8169
version: 2.3LK-1-NAPI
firmware-version: 
bus-info: 0000:03:00.0
[root@testb .vnc]# ethtool -i eth1
driver: r8169
version: 2.3LK-1-NAPI
firmware-version: 
bus-info: 0000:04:06.0
[root@testb .vnc]#
