X520-2 and X550-T2 Teaming Issues

Running latest version of Windows 10 on two newly refreshed PCs. One is running an X520-2 and the other an X550-T2, both connected to a Unifi 10G switch with each with a pair a ports set to aggregation, forced to 10G speed. Running driver 25.0

 

The result is the same on both PCs. After reboot they will connect for about 60 seconds, linked, pingable, etc. with both NICS showing active. After 60 secs on NIC goes to standby and the connection drop permanently until the next reboot. Both are set to IEEE Dynamic Aggregation and 10G on the NIC side as well.

 

If I remove aggregation both NICs in both computers work just fine (ie. nothing to do with cabling, etc)

 

I could see having a setting issue or something if it never connected, but the fact the teams works for 60 sec or so then craps out I just don't get.

 

BTW newly build machines, no other software, AV or anything. Just the latest Windows updates and driver(s).

Issue remains.  

- New Computer Build

- 25.2 Driver

- IEEE Team

- Upon reboot works for about 60 seconds and then goes to standby/active and connection stops working

Exact same issue as there has been.
