I am running Windows 2012 Datacenter Version 6.2.9200, running 13 Virtual Machines. 4 of these Virtual Machines uses NLB within the Guest Operating system (Guests are Windows 2008 R2).
The NLB seems to be functioning correctly from the guest point of view, and all network interfaces are converged, but the System Event Log on the Host is filling up with informational messages similar to the following:
Source: Hyper-V-VmSwitch
Event ID: 25
Task Category: (1018)
Level: Information
The MAC address 02-01-0A-6E-B0-97 has moved from port 62DFF413-9522-421A-83A4-B0D7A8814EB0 (Friendly Name: Dynamic Ethernet Switch Port) to port 4CE77E13-2813-4745-8191-931C11A71B05 (Friendly Name: Microsoft Network Adapter Multiplexor Driver - Virtual Switch_External).
This event occurs approximately 12 times a second. The message isn't always the same, the MAC address changes slightly, as does the port GUIDs. I have traced the MAC addresses down to being the ones used in the NLB clusters.
I can confirm that all the virtual machines which have NLB do have "Enable MAC address spoofing" enabled.
Out of the 28,093 events I currently have, 28,042 of them are this event.
How do I stop my system event log from receiving all this spam?
