Using a class-map that matches all traffic is redundant - Cisco is nice enough to do it for us.
If you have a question that states, for example:
“Ensure that all FTP traffic has a minimum bandwidth guarantee of 64 kbps, and all other traffic is marked with DSCP 0″ then I believe that best practice would be to use the class-default queue.
To satisfy the above criteria, as an example, I would do the following:
class-map match-all FTP match protocol ftp
policy-map QoS_Outbound class FTP Bandwidth 64000 class class-default set dscp default
int GigabitEthernet 0/0 service-policy output QoS_Outbound
There’s no reason to match “all” IP traffic. IOS will do that for us.

QoS related…
Would cisco look for keyword like “class class-default” if it is stated in a task to work with “all traffic”?
The reason I am asking this is because such tasks can be completed by creating a specific class with access-list that permits everything. On the other hand if the processing of class-default is differemt that processing of any other specific class, then this would be an issue. Your comments will hopefully clarify this aspect.
