How to check if linux is 10Gb network-Linux Operation and Maintenance-php.cn

How to check whether Linux is a 10G network card: 1. Use the ethtool and lspci commands to check whether the network card is a Gigabit or 10G network card; 2. Use the ifconfig command to check the machine network port, and then execute "sudo ethtool eno1" Just run the command to check whether the network bandwidth is Gigabit or 10 Gigabit.

How to check if Linux is a 10G network?

Linux Check whether the network card is a Gigabit or 10 Gigabit network card

Two commands used so far:

1, ethtool

ethtool network interface name

#ethtool em4 Settings for em4: Supported ports: [ TP ] Supported link modes: 10baseT/Half 10baseT/Full 100baseT/Half 100baseT/Full 1000baseT/Full 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: 1 Transceiver: internal Auto-negotiation: on MDI-X: Unknown Supports Wake-on: g Wake-on: d Link detected: yes

2, lspci

Currently it is Broadcom BCM5709 Gigabit network card Gigabit (10 Gigabit network card is displayed as 10-Gigabit)

#lspci -vvv | grep Ethernet 01:00.0 Ethernet controller: Broadcom Corporation NetXtreme II BCM5709 GigabitEthernet (rev 20) Subsystem: Dell PowerEdge R710 BCM5709 Gigabit Ethernet Product Name: Broadcom NetXtreme II Ethernet Controller 01:00.1 Ethernet controller: Broadcom Corporation NetXtreme II BCM5709 Gigabit Ethernet (rev 20) Subsystem: Dell PowerEdge R710 BCM5709 Gigabit Ethernet Product Name: Broadcom NetXtreme II Ethernet Controller 02:00.0 Ethernet controller: Broadcom Corporation NetXtreme II BCM5709 Gigabit Ethernet (rev 20) Subsystem: Dell PowerEdge R710 BCM5709 Gigabit Ethernet Product Name: Broadcom NetXtreme II Ethernet Controller 02:00.1 Ethernet controller: Broadcom Corporation NetXtreme II BCM5709 Gigabit Ethernet (rev 20) Subsystem: Dell PowerEdge R710 BCM5709 Gigabit Ethernet Product Name: Broadcom NetXtreme II Ethernet Controller pcilib: sysfs_read_vpd: read failed: Connection timed out

Small Knowledge:

Gigabit is the unit of data storage, usually represented by the symbol Gbit or Gb. Its conversion formula: 1 Gb = 10 to the 9th power bits = 1,000,000,000 bits.

Another common unit is Gibibit. Gibibit is used to represent binary conversion. 1 gibibit = 2 to the 30th power bits = 1,073,741,824 bits.

Linux Check whether the network bandwidth is Gigabit or 10 Gigabit

First check the machine network port

[root@namenode ~]# ifconfig eno1: flags=4163 mtu 1500 inet 192.168.60.190 netmask 255.255.255.0 broadcast 192.168.80.255 inet6 fe80::b62e:99ff:fe65:3bd6 prefixlen 64 scopeid 0x20 ether b4:2e:99:65:3b:d6 txqueuelen 1000 (Ethernet) RX packets 1034361639 bytes 496433512301 (462.3 GiB) RX errors 0 dropped 144034 overruns 0 frame 0 TX packets 977985340 bytes 163296216477 (152.0 GiB) TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0 device interrupt 16 memory 0xf7200000-f7220000

Check the port bandwidth (root or sudo permissions), Through the output below, you can see the speed line, which represents Gigabit network.

[root@namenode ~]# sudo ethtool eno1 Settings for eno1: 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: 1 Transceiver: internal Auto-negotiation: on MDI-X: off (auto) Supports Wake-on: pumbg Wake-on: g Current message level: 0x00000007 (7) drv probe link Link detected: yes
