I have been looking through the Docs and indeed it does say that native
vlan traffic is not tagged. I guess I have missed that when reading the
switching docs previously, and was always taught that all traffic is tagged.
Thanks for the clarification.
This would also mean that it is restricted to the native vlan then right?
Without a tag it could not be forwarded to any other vlan.
