1. 查看網(wǎng)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)

• 第一列表示的網(wǎng)卡編號

• 后面展示有2個10G，2個1G，2個擴展10G口，其中板載的是X722網(wǎng)卡，擴展的為82599ES網(wǎng)卡，通過查詢得知82599ES為X520類型。

2. 安裝驅(qū)動

到對應(yīng)官網(wǎng)下載對應(yīng)的tar壓縮文件

tar zxvf ixgbe-5.3.3.tar.gz

進入到對應(yīng)目錄查看README文件，該文件敘述了支持的網(wǎng)卡型號以及安裝方法

rmmod ixgbe卸載原驅(qū)動

進入src目錄進行make install

ip link show查看

加載網(wǎng)卡驅(qū)動modprobe ixgbe或modprobe ixgbe allow_unsupported_sfp=1,1

通過ethtool eth0查看對應(yīng)網(wǎng)卡端口

3. 查看網(wǎng)卡驅(qū)動版本

[root@xxx tmp]# ethtool -i eth0 driver: i40e #所使用的驅(qū)動模塊名稱 version: 1.5.10-k #驅(qū)動版本 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.查看模塊更多信息

[root@wxxxx ~]# modinfo i40e filename: /lib/modules/3.10.0-123.6.1.el6.ksyun.x86_64/updates/drivers/net/ethernet/intel/i40e/i40e.ko version: 2.4.10 license: GPL description: Intel(R) 40-10 Gigabit Ethernet Connection Network Driver author: Intel Corporation, <e1000-devel@lists.sourceforge.net> srcversion: 3977C21019A3C4865FF253A alias: pci:v00008086d0000158Bsv*sd*bc*sc*i* alias: pci:v00008086d0000158Asv*sd*bc*sc*i* alias: pci:v00008086d000037D3sv*sd*bc*sc*i* alias: pci:v00008086d000037D2sv*sd*bc*sc*i* alias: pci:v00008086d000037D1sv*sd*bc*sc*i* alias: pci:v00008086d000037D0sv*sd*bc*sc*i* alias: pci:v00008086d000037CFsv*sd*bc*sc*i* alias: pci:v00008086d000037CEsv*sd*bc*sc*i* alias: pci:v00008086d00001588sv*sd*bc*sc*i* alias: pci:v00008086d00001587sv*sd*bc*sc*i* alias: pci:v00008086d00001589sv*sd*bc*sc*i* alias: pci:v00008086d00001586sv*sd*bc*sc*i* alias: pci:v00008086d00001585sv*sd*bc*sc*i* alias: pci:v00008086d00001584sv*sd*bc*sc*i* alias: pci:v00008086d00001583sv*sd*bc*sc*i* alias: pci:v00008086d00001581sv*sd*bc*sc*i* alias: pci:v00008086d00001580sv*sd*bc*sc*i* alias: pci:v00008086d00001574sv*sd*bc*sc*i* alias: pci:v00008086d00001572sv*sd*bc*sc*i* depends: ptp vermagic: 3.10.0-123.6.1.el6.ksyun.x86_64 SMP mod_unload modversions parm: debug:Debug level (0=none,...,16=all) (int)

5.問題

有網(wǎng)卡識別不了。通過dmesg查看是由于模塊問題

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刪除驅(qū)動
modprobe ixgbe allow_unsupported_sfp=1,1
然后ifconfig即可。
