IPv6 multicast flood during sleep from i217-LM

We have a number of HP devices with the i217-LM network adapter. When they go to sleep they appear to flood the network with ICMPv6 "Multicast Listener Report".

There was another thread closed with this same problem:

Recommendation was to update to version 19 or higher driver and a link provided to the Windows 8 download. We have a mixture of Windows 7 32 and 64 bit clients. We have downloaded the version 20 drivers for Windows 7 and installed to the machines but issue still appears to be occurring. Short term fix appears to be to stop the machine from going to sleep and disabling all power saving and WoL features. Not ideal.

https://downloadcenter.intel.com/download/18713/Network-Adapter-Driver-for-Windows-7- https://downloadcenter.intel.com/download/18713/Network-Adapter-Driver-for-Windows-7-

Does anyone else have this issue and is there an update from Intel that will fix this problem? We're currently experiencing intermittent network disconnections multiple times a day for all clients on a particular segment and these ICMPv6 packets are highly suspect. The users operate in an environment where their machines could be left for long periods idling and thus going to sleep.

Unfortunately I don't have direct access to these clients currently. I'm not sure that this is specific to HP devices, i've seen reports from Dell devices as well (not on our network but on the net). Just seems to be this specific NIC.

We applied a group policy to all the machines to set their power profile to high performance and disable any kind of sleep/hibernation and since then i've not had a single drop out in 2 days.

Hi,

As far as I know, Dell drivers have a workaround for this issue. They delete all ipv6 configurations from the driver, but this still isn't a proper fix to the issue.

Intel has to find a solution for this bug on in Intel I2xx/825xx. I think this problem was found about one year ago.

I try to simulate on lab this situation with 2 or 3 machines, and doesn't detect any problem. For what I read, others try and have the same result, but with 12 machines the problem start to appears.

My customer tell me this issue push their cpu switch to 100% and drops the network(only with 6 machines on sleep)

My question is why this huge ICMPv6 packets on sleep???
