priority (Schedulers)

Syntax

Specify the packet-scheduling priority value.

Note:

Avaiable options can vary by platform and software release.

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.
low-latency—Scheduler has low latency queuing (LLQ) priority. LLQ enables delay-sensitive data to have preferential treatment over other traffic. A queue configured as a low latency queue has the highest priority over any other priority queues, including strict-high queues.

interface—To view this statement in the configuration.

interface-control—To add this statement to the configuration.

ACX7000 Series routers running Junos OS Evolved support all six levels of priority, including low-latency.

Statement introduced before Junos OS Release 7.4.

low-latency support introduced for Junos OS Evolved Release 23.4R1.
