Object
This object is used to initiate FFT measurement, and
identify the current invocation an FFT measurement,
for interface that is currently selected by
rdnCableFftConfigIfIndex.
This object is applicable to CMTS 2x8 cards, and
to BSR2000.
It is recommended that a management application will
first read this object, then perform a set to the
current value. This set may occur in the same set request
as other sets.
It is recommended that a management application will
first read this object, then perform a set to the
current value. This set may occur in the same set request
as other sets.
This object should be read again, and should return
the previous value + 1, indicating the results are valid
and the configuration has not changed. Else, another
management station has initiated another measurement
(following this procedure).
1. Get this object and store in configNum
2. Set any desired configuration objects
3. Set this object to configNum
(Note: 2 & 3 can be done in the same set request)
4. If step 3 fails, then another management station
has already set this object.
5. After short delay, get requested data from
rdnCableFftResultTable.
6. Get this object and compare with configNum + 1
7. If step 6 yields the same value, the data retrieved
in step 5 is valid.
The use of rdnCableFftConfigSpinLock is to avoid
conflicts with another SNMP command responder
application which may also be acting on the
rdnCableFftConfigObjects. Setting this object
does not provide exclusive access. Other managers
will still be able to modify these objects.
