Default IP Precedence Classifier (ipprec-default)

There are two separate tables for default IP precedence classification. All logical interfaces are implicitly assigned the ipprec-compatibility classifier by default, as described in Default IP Precedence Classifier (ipprec-compatibility).

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:

[edit class-of-service interfaces interface-name unit logical-unit-number classifiers inet-precedence]default;

Table 1 shows the forwarding class and PLP that are assigned to the IP precedence CoS bits when you apply the default IP precedence classifier.
