[j-nsp] dscp classifier doesn't work - junos 9.6

[meryem Z]

Hello Truman,

Thank you for your suggestion.
Finally i found that classification is correctly done but the interface is unable to show ingress statistics (IQ PIC) unlike the IQ2 PICs.

show interfaces queue ingress ge-0/2/0 
Ingress queue statistics are not applicable to this interface.

is this a normal behaviour for IQ PICs or I should activate something ?

Thanks.

BR.
