[Adslmib] hdsl2ShdslMIB: SpanConfNumRepeaters & StatusNumAvailRepeaters question

[Artem Polyakov <artpol84 at gmail.com>]

Hello,

I work on SNMP support for Sigrand devices (www.sigrand.com).

I have a question connected with representation of repeaters in SNMP.
Consider following example: We have a span with 

hdsl2ShdslSpanConfNumRepeaters = 6
hdsl2ShdslStatusNumAvailRepeaters = 3

How many repeaters I should represent in tables which use hdsl2ShdslInvIndex or UnitId as index?

As MIB says in hdsl2ShdslInventoryTable for hdsl2ShdslInvIndex:
Each entry in this table corresponds to a physical element in an HDSL2/SHDSL span.  It is based on the EOC unit addressing scheme with reference to the xtuC.


So I assume that I have to create entries in tables only for discovered units. But I need to know for sure.

And there is another related question:
Let's suppose that channel was working with 6 repeaters. Statistics was accumulated. Then link got down, discovery process started again. The reason of link down is a damage of segment between SRU3 & SRU4. So now we have a span with only 3 discovered repeaters (I use STU-C polling only). So if the answer for the first question is "yes, you need to represent only discovered units", I have to show only following units: STU-C, SRU1,SRU2,SRU3. But maybe it is interesting to have access to saved statistics from unavailable units? Does it consider in MIB or it is not important?


Thank you for your answers.
