For VGT mode vlan is supported by default same as bare-metal. For VST you need to use ip tool to configure VST vlan: ip link set eth<X> vf 1 vlan 2 qos 2 note: VGT mode will not work on VF if VST is configured on that VF. > > Can anyone please help me to: > > Enable VLAN guest tagging in mlx5 PF driver? > > Do I need to add any E-switch rules to do the same? > No, Nothing is required for VGT mode, just create the vlan on guest VF machine and work with it!

Please make sure VST mode is off on the VF. can you share some logs with us: on PF/VF and remote dedicated driver: ip link show <interface> ethtool -k <interface> Thanks, Saeed.
