I think LLQ is really a router term providing priority queueing over a WAN. Although the 4500 does not have WAN routing functionality, it certainly has QoS features that will allow deterministic traffic forwarding over the service provider network. We'll help to determine how best to do that as we move forward.

You can configure a Priority queue per port on Cat4500. Each port has 4 queues and queue # 3 can be confgured as a PQ or low latency queue and bandwidth can be restricted for that queue as well just like an LLQ. The only thing is once you configure LLQ/PQ on queue # 3 , all traffic egressing that queue will be shaped. There is no support for ACL for shaping queues on Cat4500.
