11.5.2 Mapping DSCP Priority
The DSCP is six bits wide, allowing coding for up to 64 different forwarding behaviors. The DSCP replaces
the ToS bits, but it retains backward compatibility with the three precedence bits so that non-DSCP
compliant, ToS-enabled devices, will not conflict with the DSCP mapping. Based on network policies,
different kinds of traffic can be marked for different kinds of forwarding. The DSCP default values are
defined in the following table. Note that all the DSCP values that are not specified are mapped to CoS value
0.
