5.6 ReferenceTypes

5.6.1 UsesPriorityMappingTable ReferenceType

The UsesPriorityMappingTable ReferenceType is a concrete ReferenceType and can be used directly. It is a subtype of NonHierarchicalReferences ReferenceType.

The SourceNode of this ReferenceType shall be an Object implementing the IIetfBaseNetworkInterfaceType or an Object of Type IetfBaseNetworkInterfaceType. Each Node shall be the SourceNode of at most one UsesPriorityMappingTable Reference.

The TargetNode of this ReferenceType shall be an instance of PriorityMappingTableType.

The UsesPriorityMappingTable ReferenceType is formally defined in Table 75.

5.6.2 HasLowerLayerInterface ReferenceType

The HasLowerLayerInterface ReferenceType is a concrete ReferenceType and can be used directly. It is a subtype of HierarchicalReferences ReferenceType.

The usage of the References is following the YANG modelling approach which is using reference pointers in the YANG-interface nodes to point to other interface nodes in lower or higher layers (“lower-layer-if”, “higher-layer-if”). The YANG Data Model for Interface Management is defined in IETF RFC 8343.

Virtual interfaces shall reference their physical interfaces with the HasLowerLayerInterfaceReferenceType. Annex A contains examples for such hierarchical references.

The SourceNode of this ReferenceType shall be an Object organized in the NetworkInterfaces folder.

The TargetNode of this ReferenceType shall be an Object organized in the NetworkInterfaces folder.

The HasLowerLayerInterface ReferenceType is formally defined in Table 76.
