[j-nsp] DSCP classifier doesn't work

[Juan Villasuso]

Hi,

I´m trying to configure IP premium services (EF) and the problem is that the
classifier applied to the input interface don't queue the packets to the
apropiate forwarding-class.

This can be achieved through filters and then forwarding to the
corresponding forwarding-class

filter expedited {
         term expedited {
                   from {
                             dscp ef;
                   }
                   then  {
                        forwarding-class expedited-forwarding;
                        accept;
                   }
          }
}

However through class-of-service classifiers didn't work.
Here is the M10 config

Any idea?. Thanks in advance
