Routing

How can I apply priority in the class of service forwarding classes? I can only find the policing-priority option available. User@bras1# run show class-of-service forwarding-class Forwarding class ID Queue Restricted queue Fabric priority Policing priority SPU priority INTERNET 0 0 0 low normal low VOIP 1 1 1 low premium low assured-forwarding 2 2 2 low normal low NC 3 3 3 low premium low I want to change the Fabric priority for some queue to high in MX104.

Hi kmaharjan,

The command to override the default fabric priority isn't supported on MX104, however any high priority egress traffic should automatically be marked for high-priority fabric queue. Could you please try to apply scheduler-maps and scheduler to the egress port as usual and check?

Will need to modify the documentation for limited MX product support: https://www.juniper.net/documentation/en_US/junos/topics/concept/fabric-priority-queuing-overview-cos-config-guide.html

Hope this helps.

Hi Riyaz,

 

Thank you for your reply. 

I just want to make the configuration simple and do not want to configure drop profiles. I just want to prioritize the traffic coming to queue 1 as high. Since there is no priority knob in mx104, is it ok to use policing-priority as premium be used?

MX104 has no fabric so this whole point is moot.
