QoS question !!

Hi i have a question in qos

how the router treats the packet with the dscp values when no action configured for marking , for example if router recieves the packet marked with AF11 and cs2 which packet gets better treatment . is it based on the order of the dscp value AF11(dscp 10) CS2 (dscp 16) ???

when and what case  CS values used in real time ??

Depends on platform's explicit QoS policy or platform's implicit (i.e. default) QoS policy.  Often default is everything is treated alike although default sometimes treats IPPrec equivalents (grouped or individually) differently, "better" for higher values; sometimes for AFxy values, higher "y"s get dropped sooner for same "x".

With explictly defined values, generally it's whatever the policy wants to happen.
