Requirement description :
Today, a colleague wants to sort out the host hardware configuration information of the test environment, and needs to provide information on the speed of the network card.
So, I inquired and recorded it here.
Operation process :
1. First query the network port name of the host through the ip a command
[root@redhat6 ~]# ip a 1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN link / loopback 00 : 00 : 00 : 00 : 00 : 00 : 00 brd 00 : 00 : 00 : 00 : 00 : 00 inet 127.0 . 0.1 / 8 scope host lo inet6 ::1/128 scope host valid_lft forever preferred_lft forever 2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP qlen 1000 link/ether 08:00:27:56:bb:92 brd ff:ff:ff:ff:ff:ff inet 192.168 . 53.6 / 24 brd 192.168 . 53,255 scope global eth0 inet6 fe80::a00:27ff:fe56:bb92/64 scope link valid_lft forever preferred_lft forever 3: eth1: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN qlen 1000 link/ether 08:00:27:6c:98:c9 brd ff:ff:ff:ff:ff:ff
Note: The network ports to be queried are eth0, eth1.
2. Query the network card setting information through the ethtool tool
[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: 0 Transceiver: internal Auto-negotiation: on MDI-X: off (auto) Supports Wake-on: umbg Wake-on: d Current message level: 0x00000007 (7) 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: 0 Transceiver: internal Auto-negotiation: on MDI-X: Unknown (auto) Supports Wake-on: umbg Wake-on: d Current message level: 0x00000007 (7) drv probe link Link detected: no
Note: In the above query information, Speed is the speed of the network card.
