Hello,
we got a shiny new DL380 Gen 9 Server - Windows 2012R2 (Hyper-V Role) installed on it.
Networking through HP Ethernet 1Gb 4-port 331i Adapter.
Server is connected to ProCurve Switch 3400cl-48G through 4 Cables (NIC-Teaming) - had it conected with only 1 Cable before - got same Problem. (Server/Switch - all latest Firmware/Drivers)
Once in a while the Server loses Network Connectivity - physical Link stays up but the connection drops the Gateway ...
When querying the ARP-Cache on the Server it shows me:
Gateway-IP-Address 00-00-00-00-00-00 invalid
So it lost the MAC of the Gateway ... ?!?
When I plug out/in the Cable - all work's without problems again. (Can also just disable Switch-Port and re-enable it)
Already searched hours and hours for a solution - but didn't find anything ... Hope someone here can help me with this odd problem?!
Thank you
Andreas Schnederle-Wagner
