Ronnie,
I think your DSCP example is true only if you configure it like this:
class-map match-all dscp
match dscp af31
match dscp ef
!
The match-any/all criteria apply only to the match statements, not just
values within a class. However, if you were to configure it like this:
class-map match-all DSCP
match dscp af31 ef
!
This would still match AF31 -OR- EF. I cannot find this clearly stated
in the doccd. I believe there is always an implicit OR for multiple
values within a given match line.
