Hello everyone.
I have a problem again.
I just set up my HyperV CLuster.
Cluster consists of: 3 HP DL360p G8 each with 2 Intel Xeon 2660 V2 10 Core and 64GB RAM.
Each server has a Mellanox ConnectX3 Dual 10Gbit network card installed and a second 10Gbit dual card (which can not RDMA).
This 10Gbit network(ConnectX3 cards) is connected to a Cisco Nexus 5548up(layer 2) switch.
If I connect 2 servers directly with Twinax cables, RDMA traffic is displayed correctly in perfmon.
So everything is configured correctly on the Windows side.
Only over the switch no RDMA traffic comes about.
Here the COnfig of the switch:

Solved!
All switch ports must be configured for RDMA traffic in trunk mode.
