4.6.3 Qu's Map

Qu's> Qu's Map page is used to map DSCP values in incoming packets to per-hop behavior and drop precedence values for
internal priority processing.
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.
