[j-nsp] Class of Service for IQ PIC

[Edwin Lok]

Hi All

for an IQ PIC, when I configure a bandwidth command as follows (from JUNOS 
docs), is the traffic shaped first or the traffic put into the scheduler first?

[edit interfaces]
t3-1/0/0:1 {
     encapsulation frame-relay;
     per-unit-scheduler;
}

[edit class-of-service]
interfaces {
     t3-1/0/0:1 {
         unit 0 {
             dlci 1022;
             scheduler-map sched-map-logical-0;
             bandwidth 10m;
         }
         unit 1 {
             dlci 1021;
             scheduler-map sched-map-logical-1;
             bandwidth 20m;
         }
     }
}

If I have ingress traffic via an interface, say ge-0/0/0 of 30Mbps all going out 
via t3-1/0/0:1.  Will the 30Mbps be first shaped to 10Mbps without regarding the 
scheduler-map?  Or will the 30Mbps be put into the queues defined in the 
scheduler-map first?

More specifically if the scheduler-map has strictly high priority meant for 
voice, will it be shaped first and result in buffered packets (adding jitter), 
or it will be put into the strictly high queue first and gets prioritized over 
other packets going into the 10Mbps subinterface?

Thanks
