Hi HaDucBinh,
  If you are connecting non trunking device to a trunk port you can get access on the native vlan. This can be very useful for example if you have a device (non DTP) that you need to autoconfigure on the other end for the trunking to be formed.
  If you don't want a 802.1q trunk to have an untagged vlan you can issue the command: vlan dot1q tag native

Hi GS!

I have question is: in 802.1Q, why we have a concept native VLAN.

I know what native vlan is! But I don't know why native vlan! Why they don't
encapsulation all vlan in dot1Q like ISL!

To reduce 4 byte in native vlan??

Thanks!
