[j-nsp] IOS to JUNOS QoS

[Andrew Jimmy]

Is there any default priority of these numbered queues like if link is
congested and packets are queuing in 0-8 different queues which one gonna be
served first.   Let's say, 3 packets are in queue 0 and 4 in queue 1 and 7
in queue 5, which one will be serialized first.

You have to enable it ... by default the PIC only has 4 queues available.

i.e.
set chassis fpc 1 pic 0 max-queues-per-interface 8  

cheers

Thanks for your reply. Can you let me know the way to use 8 supported Queues
instead of 4 usable queues.
 
CoS queues     : 8 supported, 4 maximum usable queues

               }
 
        forwarding-classes {
               queue 0 best-effort;
               queue 1 FTP-class;
               queue 2 HTTP-class;
               queue 3 network-control;
               }
 
        interface se-0/0/0 {
               unit 0{
                       scheduler-map test-policy;
                       }
               }
 
 }
 
 
Of course you need to classify the traffic to FTP-class and HTTP-class
either via class-of-service and classifier stanza, or via firewall
filter on ingress/egress.

What is the equivalent  to this in JUNOS, keeping in mind that I'm not
pasting classes intentionally. 
 
 
 
Policy-map test-policy
Class FTP
Bandwidth percent 10
Class HTTP
Bandwidth percent 20
!
Interface Serial 0/0/0
Bandwidth 1536
service-policy output test-policy
