Default Behavior Aggregate Classification Overview in ACX Series

 

The software automatically assigns an implicit default IP precedence classifier to all physical interfaces.

Other default classifiers (such as those for IEEE 802.1p bits and DSCP) require that you explicitly associate a default classification table with a physical interface. When you 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.
