The number of seconds left in the report currently being collected. When this object is modified by the management station, a new collection is started, possibly aborting a currently running report. The new value is used as the requested duration of this report, which is loaded into the associated rptrTopNPortDuration object.

When this object is set to a non-zero value, any associated rptrTopNPortEntries shall be made inaccessible by the agent. While the value of this object is non-zero, it decrements by one per second until it reaches zero. During this time, all associated rptrTopNPortEntries shall remain inaccessible. At the time that this object decrements to zero, the report is made accessible in the rptrTopNPortTable. Thus, the rptrTopNPort table needs to be created only at the end of the collection interval.

If the value of this object is set to zero while the associated report is running, the running report is aborted and no associated rptrTopNPortEntries are created.
