Actually there are 3 queues in IOS .
1) Hardware Queue :- Single Queue and Always FIFO . We can not do any thing
about it .
2) Software Queue
3) Shaping Queue ( Will be used only when shaping is turned on ) .
How Packets are enqued in Software or Shaping Queue ?
Well the answer lies in what kind of traffic shaping you you use . Here are
the details .
1) GTS : Shaping Queue : WFQ only supported . Software Queue : PQ , CQ or
FIFO
2) FRTS : Shaping Queue : PQ, CQ and FIFO Software Queue : WFQ only
3) CB-Traffic Shaping : Uses WFQ for both Shaping and Software Queue .
Well the " sh interface " o/p tells you only about the software queue and
"show traffic " will give you about shaping queue .
Hope this helps .
Thanks and Regards
Arun
