Port-level scheduling on MPCs with rich queuing enables you to apply fine-grained traffic control across up to five hierarchical scheduler node levels?from physical port down to individual queues. You benefit from granular bandwidth management, including Committed Information Rate (CIR) and Peak Information Rate (PIR) shaping at every scheduling level, configurable priority levels, and per-priority shaping. The scheduler organizes nodes hierarchically: the physical interface (Level 1), service VLAN or interface set (Level 2), customer VLAN (Level 3), session logical interface (Level 4), and the queue itself (Level 5). The goal is to give you precise, scalable control over how bandwidth is allocated and shaped across subscribers and services, reducing congestion and ensuring differentiated quality of service.
