10 Standards MIB References Generic interface managed objects are defined in the IF-MIB RFC 2863 IEEE MAC objects are defined in the EtherLike-MIB RFC 2665 Updated in draft draft-ietf-hubmin-etherif-mib-v3-00 IEEE objects are defined in the MAU-MIB RFC 2668 Updated in drafts draft-ietf-hubmin-mau-mib-v3-00 and draft-ietfhubmib-wis-mib-00 SONET/SDH managed objects are defined in RFC GFP managed objects to be defined. PoS managed objects are defined in RFC
11 RPR Management Dependencies Relationship to the Interfaces MIB The Interface MIB requires that any MI B, which is an adjunct of the interface MIB, clarify specific areas within the IF-MIB. These areas were intentionally left vague in the IF-MIB to avoid over constraining the MIB, thereby precluding management of certain media-types. The RPR MIB shall define all the RPR specific objects that cannot be derived from the generic objects in the IF-MIB Layering Model Any RPR interface is stacked over two lower-layer interfaces, representing the two spans. The layering relationship is defined in the ifstacktable (per RFC 2863). 11
12 RPR over SONET (GFP) Layering West GFP (ifindex = 5) West Sonet Path (ifindex = 3) West SONET (ifindex = 1) RPR (ifindex = 7) East GFP (ifindex = 6) East Sonet Path (ifindex = 4) East SONET (ifindex = 2) iftable (IF-MIB) ifindex 1 iftype sonet (39) 2 sonet (39) 3 sonetpath (50) 4 sonetpath (50) 5 gfp (tbd) 6 gfp (tbd) 7 ieee80217 (tbd) 12
