【Linux】如何查看网卡是千兆网卡还是万兆网卡

1、ethtool —更方便查看

eg ：

[root@test1 ~]# ethtool bond1
Settings for bond1:
Supported ports: [ ]
Supported link modes: Not reported
Supported pause frame use: No
Supports auto-negotiation: No
Supported FEC modes: Not reported
Advertised link modes: Not reported
Advertised pause frame use: No
Advertised auto-negotiation: No
Advertised FEC modes: Not reported
Speed: 1000Mb/s
Duplex: Full
Port: Other
PHYAD: 0
Transceiver: internal
Auto-negotiation: off
Link detected: yes
[root@test1 ~]# ethtool bond0
Settings for bond0:
Supported ports: [ ]
Supported link modes: Not reported
Supported pause frame use: No
Supports auto-negotiation: No
Supported FEC modes: Not reported
Advertised link modes: Not reported
Advertised pause frame use: No
Advertised auto-negotiation: No
Advertised FEC modes: Not reported
Speed: 10000Mb/s
Duplex: Full
Port: Other
PHYAD: 0
Transceiver: internal
Auto-negotiation: off
Link detected: yes
[root@in-ora-db7 ~]#

2、lspci
万兆网卡显示为10-Gigabit，千兆网卡显示Gigabit，但是不方便看网卡名称。

[root@test1 ~]# lspci -vvv |grep -i ethernet
