So when it gets a frame from a V-Lan it responds with a frame V-Lan? Or does it send a normal frame which is what i think it does when it "ignores" the vlan?
So if for example it gets a req_pdelay with a V-Lan it responds with a pdelay_response and follow up that is not in this V-Lan?

The SW will accept VLAN tagged Layer-2 frames, ignoring tpid and tci. The SW will always transmit un-tagged (non-VLAN) Layer-2 frames. Does that mean it "correctly" responds? Well, that may be a matter of opinion. The last time I looked, VLAN tags are only specified for trunking ports of switches. The only valid use of VLAN tags from a station's port is to request a priority (using VLAN zero). That option is not implemented in linuxptp. HTH, Richard
