In other words, the packet classification should be based on VLAN only. Each VM has to use SRIOV enabled with VF interface (NIC Controller used here is Intel 82599) *Problem Description:* Facing issues while enabling promiscuous mode in virtual function. We have seen many mail threads about promiscuous mode not working on VF. *Questions:* 1) Is it possible to enable promiscuous mode on virtual function? 2) Is the above supported for 82599 controller? If it is supported in the NIC, please provide the steps to enable. 3) If it is enabled, then VLAN should be the only classifier to determine the packets fate to reach the VM. Is it possible to do the classification based on the VLAN alone? Thanks, Bharath Paulraj
