Is it possible to enable 802.1p examination and verify CoS values via a ingress policy on EXOS?

I want to make a policy that exam the 802.1p value (other or inner) and map the traffic to the different QP.

And I also want to rewrite values to 0 if needed.

That is the basic stuff :-)

 

I found some info in the Policy_and_Security guide,

 

replace-dot1p—Replaces the packet’s 802.1p field with the value from the associated QoS profile.
• ingress—BlackDiamond X8, 8000 c-, e-, xl-, and xm-series modules, and Summit family switches
only.

 

Does this affect the inner dot1p bit our the outer?

If we have a “qinq-port” where the packets from the customer have a dot1p value, and we push a outer tag to it (vman - untag) 

Do we need to have “802.1p examination inner” enabled on the port to get use of this replace-dot1p?

And what about replacement?
