Associating a Scheduler with a Fabric Priority

On M320 and T-series platforms 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:



[edit class-of-service fabric scheduler-map]

priority (high | low) scheduler scheduler-name;

Note: For a scheduler that you associate with a fabric priority, you can 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.

For information about associating a forwarding class with a fabric priority, see Overriding Fabric Priority Queuing.

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:



[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;
}


}
