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 (ef)

and assured-forwarding (af) classes, by default no resources are assigned

to these forwarding classes. All af classes other than af1x are mapped to

best-effort, because RFC 2597, Assured Forwarding PHB Group, prohibits a

node from aggregating classes.

Default IP Precedence Classifier

By default, all logical interfaces are automatically assigned an implicit IP precedence

classifier called ipprec-compatibility. The ipprec-compatibility IP precedence classifier

maps IP precedence bits to forwarding classes and packet loss priorities (PLPs), as shown

in Table 54 on page 954.

The other default IP precedence classifier (called ipprec-default) overrides the

ipprec-compatibility classifier when you explicitly associate it with a logical interface. To

do this, include the default statement at the [edit class-of-service interfaces interface-name

unit logical-unit-number classifiers inet-precedence] hierarchy level:
