I210-AT multicast dropped after few days on Win10

[KnowJoe]

Hello,

I have an issue with the Intel® Ethernet Controller I210-AT. After some amount of time it stops receiving multicast traffic. We observed this issue many times in different scenarios but most of the time it was correlated with quite heavy multicast load.

We have an application listening on two multicast groups, let's name them A and B. On A, the application receives many controlling packets meaning a large number of small data chunks. Based on A there are also many dynamically created groups, let’s say C. On C groups we receive the actual data (larger payload). After some amount of time it stops receiving traffic from A, which also stops creating C groups. Command netsh int ip show joins shows correct multicast groups with references. In wireshark we can’t see packets addressed to A being received by the operating system. We checked using a hardware sniffer that packets reach the Network Adapter. Using commands: Get-NetAdapterStatistics -IncludeHidden | Format-List  -Property *, Get-Counter -Counter '\Network Adapter(*)\*' we can deduce that load drops drastically from ~100000 packets/sec to ~100 packets/sec (packets from B multicast group). Everything remains in this state until reboot or running wireshark in promiscuous mode (we already checked that setting promiscuous mode on NIC manually also works).

In our testing environment we performed a lot of tests and here we have some conclusions:

With a load of ~1600 multicast packets received/sec, ~170000 bytes received/sec, we have 100% reproduction rate of this issue after 2 hours - 2 days (usually under 10 hours).

With the same load, we changed the Network Card to Broadcom NetXtreme Gigabit Ethernet (BCM5761) and the issue didn’t reproduce for over 2 weeks (after this time we had to reinstall the machine).

Our tests covered different Windows 10 versions, drivers including the newest one and two computer models based of different motherboards:

Windows 10: 1607, 1809

Drivers: e1r65x64: 12.15.184.0 (10/10/2017), 12.16.6.0, 12.16.7.0 (06/28/2023), e1r68x64: 12.18.11.1 (7/16/2020)

Motherboards: Supermicro X11SSL-F , X11SCM-F

We also tried with disabled power saving options, and disabled speed/duplex auto-negotiation.

SSU file added in attachment.

Do you have any idea what may be the root cause of this issue, or what else should we check?

Hello @KnowJoe,

Thank you for posting in Intel Ethernet Communities. 

It appears this thread is similar with the earlier thread of yours : https://community.intel.com/t5/Ethernet-Products/dropped-multicast-traffic-after-few-days-on-IT210-AT/m-p/1529390

We are currently investigating on the SSU file and researching on this matter through the thread mentioned above.

Please be informed that we will now close this request since it is a duplicate with same description but a bit difference on the subject title.

Just feel free to post a new question if you may have any other inquiry in the future as this thread will no longer be monitored.

Thank you.

Best regards,
