linux环境中,查询网卡的速度(带宽)

需求描述:

　　今天一同事要整理测试环境的主机硬件配置信息,需要提供网卡的速度的信息,

　　所以,就查询了下,在此记录下.

操作过程:

1.首先通过ip a命令查询主机的网口名称

[root@redhat6 ~]# ip a
: lo: <LOOPBACK,UP,LOWER_UP> mtu  qdisc noqueue state UNKNOWN
    link/loopback ::::: brd :::::
    inet 127.0.0.1/ scope host lo
    inet6 ::/ scope host
       valid_lft forever preferred_lft forever
: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu  qdisc pfifo_fast state UP qlen
    link/ether ::::bb: brd ff:ff:ff:ff:ff:ff
    inet 192.168.53.6/ brd 192.168.53.255 scope global eth0
    inet6 fe80::a00:27ff:fe56:bb92/ scope link
       valid_lft forever preferred_lft forever
: eth1: <BROADCAST,MULTICAST> mtu  qdisc noop state DOWN qlen
    link/ether :::6c::c9 brd ff:ff:ff:ff:ff:ff

备注:要查询的网口是eth0,eth1.

2.通过ethtool工具查询网卡设置信息

[root@redhat6 ~]# ethtool eth0
Settings for eth0:
    Supported ports: [ TP ]
    Supported link modes:   10baseT/Half 10baseT/Full
                            100baseT/Half 100baseT/Full
                            1000baseT/Full
    Supported pause frame use: No
    Supports auto-negotiation: Yes
    Advertised link modes:  10baseT/Half 10baseT/Full
                            100baseT/Half 100baseT/Full
                            1000baseT/Full
    Advertised pause frame use: No
    Advertised auto-negotiation: Yes
    Speed: 1000Mb/s
    Duplex: Full
    Port: Twisted Pair
    PHYAD:
    Transceiver: internal
    Auto-negotiation: on
    MDI-X: off (auto)
    Supports Wake-on: umbg
    Wake-on: d
    Current message level: 0x00000007 ()
                   drv probe link
    Link detected: yes
[root@redhat6 ~]# ethtool eth1
Settings for eth1:
    Supported ports: [ TP ]
    Supported link modes:   10baseT/Half 10baseT/Full
                            100baseT/Half 100baseT/Full
                            1000baseT/Full
    Supported pause frame use: No
    Supports auto-negotiation: Yes
    Advertised link modes:  10baseT/Half 10baseT/Full
                            100baseT/Half 100baseT/Full
                            1000baseT/Full
    Advertised pause frame use: No
    Advertised auto-negotiation: Yes
    Speed: 1000Mb/s
    Duplex: Full
    Port: Twisted Pair
    PHYAD:
    Transceiver: internal
    Auto-negotiation: on
    MDI-X: Unknown (auto)
    Supports Wake-on: umbg
    Wake-on: d
    Current message level: 0x00000007 ()
                   drv probe link
    Link detected: no

备注:上面的查询信息中,Speed就是网卡的速度.
