These "OBJECT-IDENTITY" are just constant values used to represent a standardized parameter (more like a global #define in C). They are just as if the "OBJECT-IDENTITY" is defined in a PIB. We are thinking of new PIBs reusing technology dependent definitions in either existing PIBs or MIBs, whenever possible. Hope this answered your concerns. >in the previous versions of the PIB draft, these were identified by PRIDS, >they pointed towards a PRC within the same PIB... how does it work now ? In DSPIB-06, IfSchedulerCapsServiceDisc and TBParamType were of type "OBJECT IDENTIFIER", referencing objects of type "OBJECT-IDENTITY", for example qosTBParamSimpleTokenBucket and qosSchedulerPriority. Now they are of type "AutonomousType" which are TCs with syntax of "OBJECT IDENTIFIER", as defined in RFC 2579 (SNMPv2-TC). Referencing objects of type "OBJECT-IDENTITY", for example diffServTBParamSimpleTokenBucket and diffServSchedulerPriority. Hence there is no change from the compiler point of view, and no change from a usage point of view. This is not related to PRIDS. >thanks, >yacine > > >>for dsTBParamType and dsIfSchedulerCapsServiceDisc from the Diffserv MIB as >>advised during IESG review. >>The Diffserv PIB's references to the Diffserv MIB are clearly specified as: >> dsIfSchedulerCapsServiceDisc OBJECT-TYPE >> SYNTAX AutonomousType >> STATUS current >> DESCRIPTION >> "The scheduling discipline for which the set of capabilities >> specified in this object apply.
