Marko, isn't LLQ really just an extension of CBWFQ, called PQ/CBWFQ? I 
understand it's optional; however they are still tied at the hip, no?

Subject: Re: [OSL | CCIE_RS] LLQ - Is it class based or it's own?

They are different. CBWFQ (starting 12.4(20)T - HQF) and LLQ are
different queueing methods that can co-exist. They are both configured
using MQC and that gives the impression that they are somehow the same
or related, but in reality, they are not.

LLQ queue is processed first and when that processing is done, other
classes are processed according to their requirements and the queueing
scheduler for CBWFQ/HQF.
