So a few things:- When you configure VLAN stripping in Linux on a given VF.When you start VPP that interface is claimed by VPP, and I pretty sure that any prior configuration is discarded. I don't think there is a way to configure VLAN stripping in VPP. I took a quick look and I don't see RTE_ETH_RX_OFFLOAD_VLAN_STRIP being passed to DPDK anywhere. I think the VPP philosophy is that it always wants to see the VLAN. I think your approach of configuring VLAN on the sub-interfaces is the correct one. -- Regards, Ray K
