5.4 IP DSCP mapping
The IP DSCP mapping table allows you to assign a traffic class to every 
DSCP value. 
 Enter the desired value from 0 to 7 in the Traffic Class field for every 
DSCP value (0-63).

The different DSCP values get the device to employ a different forwarding 
behavior, namely Per-Hop Behavior (PHB).  
PHB classes:
X Class Selector (CS0-CS7): For reasons of compatibility to TOS/IP 
Precedence
X Expedited Forwarding (EF): Premium service. 
Reduced delay, jitter + packet loss (RFC 2598)
