Class of Service
Hierarchical Class of Service (CoS) support (ACX7024, ACX7100-32C, ACX7100-48L, and ACX7509)—Starting with Junos OS Evolved 22.3R1, ACX routers that run Junos OS Evolved support hierarchical CoS. By enabling hierarchical scheduling, an ACX interface running Junos OS Evolved can support three levels of scheduling (physical interfaces, logical interfaces, and queues). ACX routers running Junos OS Evolved do not support hierarchical CoS on integrated bridging and routing (IRB) or aggregated Ethernet interfaces. Also, hierarchical CoS schedulers should not include buffer or drop profile configurations.
To enable hierarchical scheduling, set
