    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.

    Thx
