priority (Dynamic Schedulers)


Hierarchy Level


Specify packet-scheduling priority value in a dynamic profile.


priority-level—one of the following packet-scheduling priority values:

  • low—Scheduler has low priority.

  • medium-low—Scheduler has medium-low priority.

  • medium-high—Scheduler has medium-high priority.

  • high—Scheduler has high priority. Assigning high priority to a queue prevents the queue from being underserved.

  • strict-high—Scheduler has strictly high priority. Configure a high priority queue with unlimited transmission bandwidth available to it. As long as it has traffic to send, the strict-high priority queue receives precedence over low, medium-low, and medium-high priority queues, but not high priority queues. You can configure strict-high priority on only one queue per interface.

$junos-cos-scheduler-priority—Junos predefined variable that is replaced with the packet-scheduling priority value obtained from the RADIUS server when a subscriber authenticates over the interface to which the dynamic profile is attached.
