To set DSCP field you set the thing known as TOS with IP_TOS.

To set VLAN priority, you tune VLAN f.e. to use DSCP bits in classifier
to derive VLAN priority from those bits of DSCP, which you desire. DSCP>>5
in your case.


And remember that if the box is DS aware, DS will rewrite your DSCP
in the way consistent with sustem configuration.
