更改英特尔 X710 光纤网卡速度

更改英特尔 X710 光纤网卡速度

我有一块光纤 X710 NIC,运行速度为 10,000Mb/s(SFP+)。我用它ethtool来展示它的功能:

ethtool enp1s0f0
Settings for enp1s0f0:
    Supported ports: [ FIBRE ]
    Supported link modes:   10000baseT/Full 
                            1000baseX/Full 
                            10000baseSR/Full 
                            10000baseLR/Full 
    Supported pause frame use: Symmetric
    Supports auto-negotiation: Yes
    Supported FEC modes: Not reported
    Advertised link modes:  10000baseT/Full 
                            1000baseX/Full 
                            10000baseSR/Full 
                            10000baseLR/Full 
    Advertised pause frame use: No
    Advertised auto-negotiation: Yes
    Advertised FEC modes: Not reported
    Speed: 10000Mb/s
    Duplex: Full
    Port: FIBRE
    PHYAD: 0
    Transceiver: internal
    Auto-negotiation: off
Cannot get wake-on-lan settings: Operation not permitted
    Current message level: 0x00000007 (7)
                   drv probe link
    Link detected: yes

如您所见,支持 1GE。但是,当我尝试更改其速度时,出现此错误:

sudo ethtool -s enp1s0f0 speed 1000
Cannot set new settings: Operation not supported
  not setting speed

您对这个问题有什么想法吗?我该如何更改速度模式?

来自英特尔适配器指南

基于光纤的适配器只能以原生速度全双工运行。您无法更改使用光纤电缆的英特尔适配器的速度或双工

NIC 将与链路伙伴自动协商设置,直至 1GB/s。
