<div>You actually answered the question that was at the back of my mind which was, does the OS mark L2TP control and if so with what value, I assumed it didn't mark L2TP control with anything so I would somehow have to mark with a combination of policy access list and metering policy, I already have a pwfq policy which prioritises CS6 which, thanks to your info I now know will do the trick. </div>
<div> </div>
<div>The other reason for the question was to see if anybody suggested a metering policy to mark L2TP control on the same interface as the pwfq policy as we have had some problems when attempting this.</div>
<div> </div>
<div>Is there a list of all the packets that the OS marks by default?</div>
<div> </div>
<div>Thanks</div>
