I am looking at some MIBs for a Dynamic Message Sign (DMS) and I see some examples of Object IDs that I don't understand.
In those examples, some objects in the DMS MIB definition have the Object Id finished with a 0 (zero) such as: "1.3.6.1.4.1.1206.4.2.3.4.8.0" where the standard would call for only "1.3.6.1.4.1.1206.4.2.3.4.8" What is the significance of that final "0"? I tried to read the RFC 1212 - Concise MIB Definitions, and I found the following reference: "If the INDEX clause is not present, and the object type corresponds to a non-columnar object, then instances of the object are identified by appending a sub-identifier of zero to the name of that object." Is this the correct justification for having that ) there? Also, for objects defined as Sequence Of, an "INDEX" clause is present in the Object's definition. The example has in that case 2 extra integers, such as: "1.3.6.1.4.1.1206.4.2.3.5.8.1.1.3.1" instead of just "1.3.6.1.4.1.1206.4.2.3.5.8.1.1" I think that the last two integers are used to identify (first) the selected member/field of the sequence type and (second) the index of the sequence within the SEQUENCE OF type. Can anybody confirm these suppositions and/or eventually to point me to some readings that can clarify these aspects?
