According to this: https://communities.intel.com/message/220048, driver upgrade should fix it.

Glad you got some rest!

Hi Joe,

You are correct…

Once I was able to get some sleep (very long weekend) I went back and looked at the logs and data we had collected and sure enough the problem only occurred between 7PM and 8AM on the nights in question. We went back and confirmed that both HP desktops were configured to sleep and had Wake-On-LAN enabled within the BIOS. As your alluding to there are quite a few articles on the Internet detailing this exact same problem. Now I’m wondering what’s the fix? A Windows driver upgrade, a BIOS upgrade?

Thanks for the comment!

Great write up Mike.

Thanks for the comment Frank,

I too read Garrett’s post a few months back… was very interesting and definitely a warning sign for network engineers and administrators as IPv6 starts to take hold.

In this case there’s a known issue with the Intel I217-LM NIC driver that I believe is the ultimate culprit.

Cheers!

I suspect this won’t be the last growing pain that IPv6 has in store for enterprise networks…
