I know random-detect is diffserv-aware, but I just can't seem to find a document that says WFQ is diffserv-aware. Can someone help me here?
Thanks,

Hi William
WFQ is ip precedence aware.It detects higher priority packets marked with ip precedence bits.
And will allocate more bandwidth to the higher priority packets in times of congestion.
In flow-based WFQ, packets are classified by flow. Each flow corresponds to a separate output queue. When a packet is assigned to a flow, it is placed in the queue for that flow. During periods of congestion, WFQ allocates a portion of the available bandwidth to each active queue.
The issue with it is it can become a little to FAIR scheduling traffic from other ques voice quality could be jepordised.
If using voice try LLQ

Hi Allan:
Yes, I do know that WFQ is IP Precedence-aware, but I need to know if it reacts to DSCP-marked packets. For example, if I have AF41, Af42, AND AF43 packets arrive at the WFQ output queue, how does WFQ react?
Thanks,
William
