Default IP Precedence Classifier

explicitly associate a default classifier with a logical interface, you are in effect overriding
the implicit default classifier with an explicit default classifier.
NOTE: Although several code points map to the expedited-forwarding (

node from aggregating classes.

Overview of BA Classifier Types
By default, all logical interfaces are automatically assigned an implicit IP precedence
classifier called
ipprec-compatibility
maps IP precedence bits to forwarding classes and packet loss priorities (PLPs), as shown
in Table 54 on page 954.
