Hi all,

  Is it true that in CBWFQ, the IP precedence of a packet does not have a
direct effect on the weighting of conversation queues? That's how Im
understanding the doc on CBWFQ:

http://www.cisco.com/univercd/cc/td/doc/product/software/ios121/121cgcr/qos_c
//qcprt2/xtocid16

As I understand it IP precedence is relevant only in the flow differentiation
step. Queues are weighed explicitly through the bandwidth command.

But then at the near the end of the section the author goes on to say: "CBWFQ
uses the weights assigned to the queued packets to ensure that the class queue
is serviced fairly."

Is the guy talking about IP precedence weight or bandwidth-assigned weight?

Thanks,
   Joe
