Which queuing feature enforces strict-priority servicing for voice/video traffic?

Low Latency Queuing (LLQ) combines the benefits of Class-Based Weighted Fair Queuing (CBWFQ) with strict priority queuing. It allows you to designate specific traffic classes, typically voice and video, as priority queues, ensuring they are serviced before any other traffic as long as they do not exceed their configured bandwidth limit. This strict priority servicing is crucial for real-time applications to minimize delay and jitter. CBWFQ, while allowing bandwidth allocation per class, does not offer strict priority. Link Fragmentation and Interleaving is a technique to reduce serialization delay on slow links, not a queuing mechanism for strict priority. AutoQoS is a feature that automates QoS configurations, but LLQ is the underlying mechanism it often configures for strict priority.
