when you are configuring dot1q subinterfaces on a router , the router receives a dot1q tagged frame with a vlan id and then the subinterface with the same vlan id receives it , but what happens if the router receives a regualr frame
that isnt tagged the router needs to know on what subinterface this frame should land so the native option does this it tells the router that this subinterface should get the frame.
so to summarize the native option tells the router what subinterface to use when no 802.1q tag is received.
but dont worry when you are sending frames from the subinterface with the native option the frame will be tagged with dot1q ,
another important thing is make sure the native vlan on the router is the same as the native vlan on the switchport that the router is connected to.
