Release Information

Statement introduced before JUNOS Release 7.4.


Specify packet-scheduling priority value.


priority-level can be one of the following:

  • 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.

Usage Guidelines
