Release Information
Statement introduced before Junos OS Release 7.4.
Statement introduced in Junos OS Release 12.1X48 for PTX Series Packet Transport Routers.
Statement introduced in Junos OS Release 12.2 for ACX Series Routers.
Description
Specify the packet-scheduling priority value.
Options
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.
 | Note: The strict-high priority level is the only priority level supported on ACX Series Routers. However, multiple strict-high priority queues can be configured per interface on ACX Series Routers. |
Required Privilege Level
interface—To view this statement in the configuration.
interface-control—To add this statement to the configuration.
