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 3 in the Traffic Class field for every
DSCP value (0-63).
Figure 25: IP DSCP mapping table
The different DSCP values get the device to employ a different forwarding
behavior, namely Per-Hop Behavior (PHB).
PHB classes:
Class Selector (CS0-CS7): For reasons of compatibility to TOS/IP
Precedence
Expedited Forwarding (EF): Premium service.
Reduced delay, jitter + packet loss (RFC 2598)
Assured Forwarding (AF): Provides a differentiated schema for handling
different data traffic (RFC 2597).
