Round Trip Time Monitor Stats Collect Drops

1.3.6.1.4.1.9.9.42.1.3.2.1.5

The number of occasions when a RTT operation could not be initiated because some necessary internal resource (for example memory, or SNA subsystem) was not available, or the operation completion could not be recognized. Since a RTT operation was never initiated or was not recognized, the completion time of these operations are not accumulated, nor do they increment rttMonStatsCaptureCompletions (in the expected Distribution Bucket). When the RttMonRttType is 'pathEcho', and this error occurs and the rttMonStatsCapturePathIndex cannot be determined, this error will be accumulated in the source to target path, that will always exist. This object has the special behavior as defined by the ROLLOVER NOTE in the DESCRIPTION of the ciscoRttMonMIB object.
