Hello
The Result is as below
Address A:Port A | Address B:Port B | bps A->B
1.1.1.1:4848 | 1.1.1.2:4848 | 1749898
1.1.1.1:4646 | 1.1.1.2:4646 | 2208362
1.1.1.1:3434 | 1.1.1.2:3434 | 1685762
1.1.1.1:2626 | 1.1.1.2:2626 | 2057111
1.1.1.1:1000 | 1.1.1.2:1000 | 1801985

Subject: Priority Queuing on MX series
Hi all.
I have never control juniper box, anyway I need you guys to help me for QoS
configure on MX series as a Priority Queuing
I think classify, Marking is ok. But scheduler is not okay
I sent 5 flow traffic( port 4848 is DSCP48, 4646 is DSCP46, 3434 is 34, 2626
is 26, 1000 is 0) with 2Mbps each flow except DSCP34(8Mbps)
--> Total 16Mbps. Interface rate-limit is 10Mbps
So, if my Juniper QoS configuration is correct then 1. DSCP48 and 46 are
supposed to be 2Mbps 2. DSCP34 is supposed to be 6Mbps.
3. The others(DSCP26,0) are 0Mbps.
But the result is as below
Address A Port A Address B Port B Packets Bytes Packets A->B
Bytes A->B Packets A<-B Bytes A<-B Rel Start Duration bps A->B
bps A<-B
1.1.1.1 4848 1.1.1.2 4848 1943 2024606 1943

Plz let me know Juniper QoS configuration as a Priority Queuing
