不兼容萬(wàn)兆光模塊
ixgbe光纖網(wǎng)卡的驅(qū)動(dòng)在默認(rèn)情況下不支持第三方兼容光模塊,會(huì)導(dǎo)致網(wǎng)卡驅(qū)動(dòng)加載失敗怠缸,表現(xiàn)為,執(zhí)行l(wèi)spci |grep 82599能看到網(wǎng)卡在pci設(shè)備中
06:00.0 Ethernet controller: Intel Corporation 82599EB 10-Gigabit SFI/SFP+ Network Connection (rev 01)
06:00.1 Ethernet controller: Intel Corporation 82599EB 10-Gigabit SFI/SFP+ Network Connection (rev 01)
但是使用ifconfig -a命令钳宪,卻找不到網(wǎng)卡揭北,使用demsg可以看到以下出錯(cuò)信息:
ixgbe 0000:06:00.0: failed to load because an unsupported SFP+ module type was detected
解決問(wèn)題的方法是如下
執(zhí)行rmmod ixgbe,卸載掉驅(qū)動(dòng)吏颖,
然后執(zhí)行modprobe ixgbe allow_unsupported_sfp=1
驅(qū)動(dòng)對(duì)allow_unsupported_sfp的解釋為:
allow_unsupported_sfp:Allow unsupported and untested SFP+ modules on 82599-based adapters (uint)
重新加載后搔体,大部分情況下ifconfig就能夠看到網(wǎng)卡信息了。
