Jason,

Thank you very much, you have good explanation. Qos is my weak area also, and multicast is the weakest :)

Once again, thx a lot

(again I'm no QoS expert (yet), but from what I believe to be true:)

Yes, rate-limit is policing. It's the legacy way of doing it and It does NOT queue / buffer...just limit the traffic rate. Unlike queuing, you can do it inbound or outbound. Traffic Shaping, however, does queuing aka only inbound.
 
HTH a little

 One more thing, what is the difference between rate-limit and traffic-shape
 on an interface ?
 
 
 
 Is rate-limit treat traffic like policing the traffic and traffic-shape like
 shaping the traffic with buffer ?
 
 
 
 Thanks a lot guys, my lab date is on two weeks, very nervous about it.
