Identifies the repeater for which a top N report will be prepared (see rptrInfoId). If the value of this object is positive, only ports assigned to this repeater will be used to form the list in which to order the Top N table. If this value is zero, all ports will be eligible for inclusion on the list.

The value of this object may not be modified if the associated rptrTopNPortRowStatus object is equal to active(1).

If, for a particular row in this table, the repeater specified by the value of this object goes away (is removed from the rptrInfoTable) while the associated rptrTopNPortRowStatus object is equal to active(1), the row in this table is preserved by the agent but the value of rptrTopNPortRowStatus is changed to notInService(2), and the agent may time out the row if appropriate. If the specified repeater comes back (reappears in the rptrInfoTable) before the row has been timed out, the management station must set the value of the rptrTopNPortRowStatus object back to active(1) if desired (the agent doesn't do this automatically).
