Associating Schedulers with Fabric Priorities

date_range 29-Nov-23

On Juniper Networks M320 routers, MX Series routers, T Series routers and EX Series switches only, you can associate a scheduler with a class of traffic that has a specific priority while transiting the fabric. Traffic transiting the fabric can have two priority values: low or high. To associate a scheduler with a fabric priority, include the priority and scheduler statements at the [edit class-of-service fabric scheduler-map] hierarchy level:

content_copy zoom_out_map
[edit class-of-service fabric scheduler-map]
priority (high | low) scheduler scheduler-name;
Note:

For a scheduler that you associate with a fabric priority, include only the drop-profile-map statement at the [edit class-of-service schedulers scheduler-name] hierarchy level. You cannot include the buffer-size, transmit-rate, and priority statements at that hierarchy level.

Example: Associating a Scheduler with a Fabric Priority

Associate a scheduler with a class of traffic that has a specific priority while transiting the fabric:

content_copy zoom_out_map
[edit class-of-service]
schedulers {
    fab-be-scheduler {
        drop-profile-map loss-priority low protocol any drop-profile fab-profile-1;
        drop-profile-map loss-priority high protocol any drop-profile fab-profile-2;
    }
    fab-ef-scheduler {
        drop-profile-map loss-priority low protocol any drop-profile fab-profile-3;
        drop-profile-map loss-priority high protocol any drop-profile fab-profile-4;
    }
}
drop-profiles {
    fab-profile-1 {
        fill-level 100 drop-probability 100;
        fill-level 85 drop-probability 50;
    }
    fab-profile-2 {
        fill-level 100 drop-probability 100;
        fill-level 95 drop-probability 50;
    }
    fab-profile-3 {
        fill-level 75 drop-probability 100;
        fill-level 95 drop-probability 50;
    }
    fab-profile-4 {
        fill-level 100 drop-probability 100;
        fill-level 80 drop-probability 50;
    }
}
fabric {
    scheduler-map {
        priority low scheduler fab-be-scheduler;
        priority high scheduler fab-ef-scheduler;
    }
}
