Hello Joseph,
Here is what the CD says at the following link:
http://www.cisco.com/univercd/cc/td/doc/product/software/ios120/120newft/120t/120t5/cbwfq.htm#25297
<SNIP>
"The class-default class is used to classify traffic that does not fall into
one of the defined classes. Once a packet is classified, all of the standard
mechanisms that can be used to differentiate service among the classes
apply. The class-default class was predefined when you created the policy
map, but you must configure it. If no default class is configured, then by
default the traffic that does not match any of the configured classes is
flow classified and given best-effort treatment."
</SNIP>
So, if you want to do something with the default traffic, like give it a
precedent, or a bandwidth, or... whatever, then use the default class. If
you really don't care about this traffic, then it will be handled in a
best-effort manner.
In your example, it seems you are mainly worried about dropping a certain
type of traffic. Seems that is all you need to do with it.
