RE: V2 Changes for next RFI v2 MIB (draft 10)

All,

To address the concern raised by Minnie, may I suggest that we add to the DESCRIPTION clause of the row status column to define a time interval that the agent must remove rows that remain in the 'notInService' or 'notReady' state.

This is defined under "Interaction 4: Making the Conceptual Row Available" in RFC 2579. 

Taken from RFC2579 Section 2, Row Status, Interaction 4:  

            "If the management station is prevented from setting the
            status column to `active' (e.g., due to management station
            or network failure) the conceptual row will be left in the
            `notInService' or `notReady' state, consuming resources
            indefinitely.  The agent must detect conceptual rows that
            have been in either state for an abnormally long period of
            time and remove them.  It is the responsibility of the
            DESCRIPTION clause of the status column to indicate what an
            abnormally long period of time would be.  This period of
            time should be long enough to allow for human response time
            (including `think time') between the creation of the
            conceptual row and the setting of the status to `active'.
            In the absence of such information in the DESCRIPTION
            clause, it is suggested that this period be approximately 5
            minutes in length.  This removal action applies not only to
            newly-created rows, but also to previously active rows which
            are set to, and left in, the notInService state for a
            prolonged period exceeding that which is considered normal
            for such a conceptual row."

Thanks,
Andy

Hi, Eduardo,

   Thanks a lot for listening to me. I am happy with the new text.

    But I still have concern about saving notInService or notReady rows for 
modulation profiles into NVRAM and have them persistent across CMTS 
reboot,  especially for the rows with inconsistent attributes which is 
allowed for rowStatus in 'notInService' and 'notReady'.

   Though this is extreme case, but since the MIB or spec does not prevent 
to do so or does not make it optional, that means CMTS MUST implement such 
capability to save rows with inconsistent attributes into NVRAM which is a 
waste of CMTS resource and complicated the implementation for no or little 
gain.

   Possible to make it an optional that saving rows with inconsistent 
attributes into NVRAM and persistent across reboot ?

    Thanks a lot for your advice !
    Minnie
