Mapping SNMP Collections to CIM Classes

The following rules apply when mapping SNMP collections to CIM classes. Unless otherwise specified, these rules apply to both scalar and table collections:

• A collection maps to a CIM class.
• The elements of a collection map to properties of a CIM class.
• All generated CIM class definitions must be derived from the SnmpObjectType class. The following class definitions parent all generated class definitions:

  [abstract]
  class SnmpMacro
  {
  };
  
  [abstract]
  class SnmpObjectType:SnmpMacro
  {
  };

• The mapping process generates CIM class names by concatenating "SNMP_", the MIB module identity name, "_", and the collection's object descriptor. For example:

  system translates to SNMP_RFC1213_MIB_system

  ifTable translates to SNMP_RFC1213_MIB_ifTable

  In all cases, hyphens (-) in SNMP MIB identifiers map to underscores (_) in CIM class names.

• Naming conflicts can occur due to CIM name case-insensitivity. If a naming conflict occurs, the provider chooses one of the conflicting group definitions and ignores the remaining definitions.
• The identity name of the MIB module that contains the collection maps to the CIM class qualifier Module_Name.
• The object identifier of the fabricated collection maps to the CIM class qualifier Group_Objectid.
• The MIB module imports list (obtained from the MODULE-IDENTITY macro definition) maps to the CIM class qualifier module_imports. This qualifier contains a comma-separated list of module names.
