I have a cluster, 2 nodes. There are repeating events id 25, every few second:

I am in the same boat, also seeing multiple event with ID 25.
Example:
The MAC address 00-15-5D-D4-23-00 has moved from port 958DFE2E-7078-4D1D-828F-8C59139F35EA (Friendly Name: vswitch10G_External) to port E3DF345B-7C4C-436B-9EF1-5432B21A2F07 (Friendly Name: vNICMGMT).
Config:

I am getting this issue as well, it is causing intermittent connection issues as well as false alerts on our monitoring software telling us a Hyper-V server is down. I have 4 identical installs at 4 different sites and only one Hyper-V server is showing this issue. The Team 1 Mac address is the one that shows up in the logs over and over. This happens over and over about 20 times every 10 minutes.
The MAC address EC-EB-B8-97-AB-BF has moved from port 8A69D434-AC4B-4E50-B42B-9A18DDDC51FD (Friendly Name: Microsoft Network Adapter Multiplexor Driver - Virtual Switch_External) to port 3BBEFC3E-861E-41FD-A4D0-27CCA74B9D21 (Friendly Name: Microsoft Network Adapter Multiplexor Driver - Virtual Switch).

Hi Chris,
I have the same issue on Supermicro servers with onboard Intel X540-AT2 10Gb ethernet. Driver version 4.1.76.0. Profile: Virtualization Server (Hyper-V). Windows 2016 (14393.2670) Datacenter Hyper-V 3-node Cluster with S2D and 2018-12 CU(KB4483229) installed. SET teaming was configured at one time but later removed because of frequent disconnects. Another standalone 2016 Hyper-V server with the same hardware and no SET teaming does not have any ID 25 events.
All cluster nodes get about 1500 ID 25 events per hour. In my case the event flood stops immediately after updating the VlandID of the problem ManagementOS VMNetworkAdapter. It is a temporary fix. The event 25 flood usually comes back a few days or weeks later.
Get-VMNetworkAdapterVlan -ManagementOS
Set-VMNetworkAdapterVlan -VMNetworkAdapterName vEthernet* -ManagementOS -Access -VlanID ##
Hope that helps.

Also having the same issue on 1 of 2 severs. Both servers are specced out the same, same OS (Server 2016), but only one of the servers is having the issue.
I believe the server with the issue at one point had some of it's NICs teamed - however, that is no longer the case.
Moved all the running VMs off the server with the issue. Still 3 test VMs on the server, but they aren't running.
Deleted the HyperV Switch and the issue seemed to go away (duh) - but after re-creating the HyperV Switch the warnings start coming back - even though all the VMs on the system are turned off.
Have upgraded all NIC (Intel X550/I350) drivers on the system to whatever the latest is.
In the process up installing 2019-01 Cumulative Update to see if it's any help.
Whatever the issue is, it doesn't SEEM to impart performance - at least not to the point that's it is noticeable.

Having the same errors logged with Broadcom 57800 10G in Dell 730xd. Any update?
Only 1 of 9 servers logging the error and that server loses network connectivity. All interfaces show up but no traffic passes. No errors or information found on the switch side.
Discovered that disabling the domain firewall allows traffic to flow. Re-enabling the firewall, the traffic continues to flow. Compared the firewall settings to the other working servers, no difference.
