This object gives the number of contiguous 15 minute
intervals for which valid FEC PM data is available
for the particular interface.
The actual performance data is available in the following
Table
coiFECIntervalTable
The value of this object will be n (where n is the maximum
number of 15 minute intervals supported at this interface),
unless the measurement was (re-)started within the last
(nx15) minutes, in which case the value will be the
number of 15 minute intervals for which the agent
has some data.
This object reports a value 0, if FEC is disabled by setting
coiIfControllerFECMode to 'disable'.
