I would think in essence this is can be completed both ways, I would
think on the test you'd have to make sure the words used wouldn't
include default.If the term default was used Im sure you know ISL would
be your T protocol of choice.

Esentially all vlans are tagged either way using do1q native command.

Are you sure the question didn't state " All traffic transvering the
trunk should be tagged" ??

Subject: switch trunk allow vlan except 1 (valid for not allowing
untagged packets across a trunk?)

Hi,

Can anyone give their thoughts on this please?

Question:-

"All traffic sent over these trunk links should be tagged with a VLAN"

Int fa0/7

Swi trunk encap dot

Swi mode trunk

Swi trunk native vlan 1 (for completeness)

Swi trunk allow vlan except 1

The solution to this question required the configuration of the trunk to
be ISL. Being thick I forgot ISL tags all packets. Do the above
solution solve the question?

I have a funny feeling I have asked this before J

Cheers

Alex
