I agree with you, Dave! By default, custome queue has queue-limit of 20
packets while it is 64 packets for
a class policy in a policy map. MQC in the solution guide does decrease the
queue for WWW from 64 to 30
instead of incerasing from 20 to 30 as in the source custome queue. With this
lost, tail drop will occur when interface is
in congestion because the queue is not deep enough for hoding WWW packets.

Interesting, I would think all queues except WWW would have a "queue-limit
20" statement in the solution. Looking at the solution posted below the
queue depth for all classes is 64. Any idea why?
