SR-IOV - LACP / VLAN Tagging

[Raducanu]

Hello,

i try to configure LACP and VLAN Tagging with SR-IOV NICs inside a Windows Server 2012 VM.

Overview:

Dell R720 (VMware vSphere 5.1) with Intel X520 10GbE DualPort NIC. Both Ports are connected to a Juniper Virtual Chassis

A LACP "team" is configured with both ports and also two VLANs are definied (tagged).

ae9 {
        description "amaffmesx108 10G/IOSRV";
        aggregated-ether-options {
            lacp {
                active;
            }
        }
        unit 0 {
            family ethernet-switching {
                port-mode trunk;
                vlan {
                    members [ File-Server SQL-Heartbeat ];
                }
            }
        }

I enabled SR-IOV for the both X520 Ports (one VF for each Port) and added both VF via DirectPathIO to the Windows Server 2012 VM.

Inside the VM, Windows detects both VF correctly. So i creaded a Team with both VF, set teaming mode to LACP and loadbalancing to adresshash. But i get "Faulted LACP negotiation".

Is LACP not working with SR-IOV?

Or is there something else i'm missing?

Thank's a lot!
