Default Behavior Aggregate Classification Overview
The software automatically assigns an implicit default IP precedence classifier to all logical interfaces.
 | Note: Only the IEEE 802.1p classifier is supported in Layer 2 interfaces. You must explicitly apply this classifier to the interface as shown in Default IEEE 802.1p Classifier. |
If you enable the MPLS protocol family on a logical interface, a default MPLS EXP classifier is automatically applied to that logical interface.
Other default classifiers (such as those for IEEE 802.1p bits and DSCP) require that you explicitly associate a default classification table with a logical 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. |
You can apply IEEE 802.1p classifiers to interfaces that are part of VPLS routing instances.
