1) chasConfigTable How exactly does this table work ?. I see (at least) 2 implementations. a) The table contains only those relationships that actually exist. Rows are created/deleted by a set of chasConfigStatus. b) The table contains all valid relationships. chasConfigStatus indicates which are currently in use and which are not. Option b) makes visible all potential configurations. Using a), how would a manager know if a specific slot was able to attach to a specific segment ?. In either case, why are chasConfigSlot, chasConfigEntity and chasConfigSegment read-write and not read-only ?. Using option b), these objects are determined by the HW present in the chassis. Using option a), these objects are set implicitly when the manager creates a row by setting chasConfigStatus to valid(1). Am I missing something ?. 2) Double segment attachments. Someone pointed out the problem of having one specific slot host 2 connections to the same segment. This is a severe limitation on switched ethernet and on ATM. On these medias, a single entity could increase the bandwidth of its network connection by having multiple connections to the same network. This is a severe limitation. We just can't design a MIB with such an obvious flaw. 3) chasConfigIndexType Imagine a combined repeater/bridge entity that takes up one slot and attaches to one segment. Thus it has one entry in the chasConfigTable. Does chasConfigIndexType point to an interface or a repeater port in this case ? It seems to me that there should be an instance of chasConfigIndexType for each function defined in chasEntityFunction. 4) chasConfigIndexValue If the entity in question is a repeater with multiple ports per segment (fairly typical I guess), which port instance does chasConfigIndexValue reference ?.
