Hi Ato,
We need to see the class definition portion of it (class-map) to be sure.
Do yo have it?
The class-map acts as the filter and determine how precise is that filter.
Did you use UDP port range when defining class RTP? If you did, other packets
with UDP port outside that range will fall under UDP.
So assuming you have two classes with totaly different port range, does the
order it is defined in a policy affect the behaviour/treatment?
My guess is same as yours i.e. the order won't make any difference, but who
knows ... may be some of you encountered a case or read a doc where the order
*does* make a difference in behaviour.
