I have Windows Server 2012R2 with Hyper-V role installed. I,m using network Team.

When the server starts I receive a error - Hyper-V-VmSwitch EventID 106 - in system event log.

What are the NICs being teamed and the teaming setting?

Do the NICs have different capabilities?  Is SR-IOV enabled?

I teamed two 10GB NICs.

Team mode is LACP. SR-IOV is not enabled.

Hi Simonaa,

Please refer to  the  similar thread  :

http://social.technet.microsoft.com/Forums/windowsserver/en-US/e06fede9-931c-4dee-8379-4fd985e20f0a/hypervvmswitch-eventid-106?forum=winserverhyperv

Hope this helps

Hi Elton,

I checked similar tread, but there talking about sum-queue mode.

My teams in Hyper-V host are configured to min-queue mode.

My Hyper-V server has 4 processors with 10 core each (40 cores). I'm using 2 teams. Each team has two 10 GB NICS.

The problem (event id 106) is present in both teams.

In "Windows Server 2012 R2 Nic teaming guide" I found information that I must configure each NIC in team to use same processors. So, if I understand well I must run command below on each NICs in both teams:

Set-NetAdapterRss -name NIC1 -BaseProcessorNumber 0 -MaxProcessorNumber 39

Best regards, Simon

Hi ,

If I understand correctly , it is needed to run this command on each team members not the "Teaming NIC".

Best Regards

Elton Ji

Hi,

I run this command:

Set-NetAdapterRss -name "10GE-S09-SP", "10GE-S09-SP" -BaseProcessorNumber 0 -MaxProcessorNumber 16

Now both interfaces in team: Team-Cluster use same processors:

And the problem (event id 106) is still present....

Hi Simon,

Has the problem been solved ?

Your CPU is  AMD ?

BTY , "switch dependent" and "address hash" is the teaming configuration ?

Best Regards

Elton Ji

Hi Elton,

No, the problem is still present....

Teaming configuration is LACP(switch dependant) anf Hyper-V port....

Regards, Simon

Hi Simonaa,

Please try to use the Teaming configuration :  "switch dependent" and "address hash" .

As for this command : Set-NetAdapterRss -name "10GE-S09-SP", "10GE-S09-SP" -BaseProcessorNumber 0 -MaxProcessorNumber 16 

If your cpu is AMD there is no problem , bu if  you are using Intel CPU the "MaxProcessorNumber" normally should be a odd number .

Hope this helps

Best Regards
