Support for low-latency queuing (ACX7024, ACX7100-32C, ACX7100-48L, and ACX7509)—Starting in Junos OS Evolved Release 23.4R1, the listed ACX7000 routers support low-latency queuing (LLQ) for both port-level and hierarchical scheduling. LLQ enables delay-sensitive data to have preferential treatment over other traffic. A queue configured as a low-latency queue has higher priority over any other priority queues, including
strict-high
queues.To configure a queue as a low latency queue, set
priority low-latency
at the[set class-of-service schedulers scheduler-name]
hierarchy level and apply the scheduler to the relevant forwarding class. -
Support for six scheduler priority levels (ACX7024, ACX7100-32C, ACX7100-48L, and ACX7509)—In releases earlier than Junos OS Evolved Release 23.4R1, ACX7000 Series routers supported two scheduler priority levels: strict-high and low. Starting with Junos OS Evolved 23.4R1, the listed ACX7000 routers support six scheduler priority levels. The levels are, in order of priority:
low-latency
strict-high
high
medium-high
medium-low
low
This support is for both port-level and hierarchical scheduling.
