Hi,
When faced with a question that states that we must "ensure that all
traffic that is sent over this link is tagged with a vlan header" and
the link is a dot1q trunk, the way I see it we have two options:
We can change the trunk's native vlan and not allow it on the trunk.
Or
We can use the vlan dot1q tag native, and guarantee that there is no
untagged vlan on the trunk.
I have two questions regarding this:
What happens on both situations to DTP,VTP, etc traffic? Are their PDU's
encapsulated also?
Why would we choose one method over another (besides the simplicity of
the latest)?
TIA
