1. 查看网卡信息

lspci | grep -i 'eth'

1a:00.0 Ethernet controller: Intel Corporation Ethernet Connection X722 for 10GbE SFP+ (rev 09)
1a:00.1 Ethernet controller: Intel Corporation Ethernet Connection X722 for 10GbE SFP+ (rev 09)
1a:00.2 Ethernet controller: Intel Corporation Ethernet Connection X722 for 1GbE (rev 09)
1a:00.3 Ethernet controller: Intel Corporation Ethernet Connection X722 for 1GbE (rev 09)
3b:00.0 Ethernet controller: Intel Corporation 82599ES 10-Gigabit SFI/SFP+ Network Connection (rev 01)
3b:00.1 Ethernet controller: Intel Corporation 82599ES 10-Gigabit SFI/SFP+ Network Connection (rev 01)
  • 第一列表示的网卡编号

  • 后面展示有2个10G,2个1G,2个扩展10G口,其中板载的是X722网卡,扩展的为82599ES网卡,通过查询得知82599ES为X520类型。

2. 安装驱动

  1. 到对应官网下载对应的tar压缩文件
  2. tar zxvf ixgbe-5.3.3.tar.gz
  3. 进入到对应目录查看README文件,该文件叙述了支持的网卡型号以及安装方法
  4. rmmod ixgbe卸载原驱动
  5. 进入src目录进行make install
  6. ip link show查看
  7. 加载网卡驱动modprobe ixgbemodprobe ixgbe allow_unsupported_sfp=1,1
  8. 通过ethtool eth0查看对应网卡端口

3. 查看网卡驱动版本

[root@xxx tmp]# ethtool -i eth0
driver: i40e #所使用的驱动模块名称
version: 1.5.10-k #驱动版本
firmware-version: 3.2d 0x80000b8a 255.65535.255
expansion-rom-version:
bus-info: 0000:1a:00.0
supports-statistics: yes
supports-test: yes
supports-eeprom-access: yes
supports-register-dump: yes
supports-priv-flags: yes

4.查看模块更多信息

[root@wxxxx ~]# modinfo i40e

5.问题

  1. 有网卡识别不了。通过dmesg查看是由于模块问题
ixgbe 0000:3b:00.1: PCI INT B -> GSI 44 (level, low) -> IRQ 44
ixgbe 0000:3b:00.1: setting latency timer to 64
ixgbe: 0000:3b:00.1: ixgbe_check_options: FCoE Offload feature enabled
ixgbe 0000:3b:00.1: failed to load because an unsupported SFP+ or QSFP module type was detected.
ixgbe 0000:3b:00.1: Reload the driver after installing a supported module.

方法:
rmmod ixgbe删除驱动
modprobe ixgbe allow_unsupported_sfp=1,1
然后ifconfig即可。
