This is the standard RowStatus control column used to create or delete a row in the performance data update-period table, which sets a refresh interval per interface checkpoint type, per the source description noting all columns must have valid values before a row can be activated. A network administrator sets this to activate a new update-period configuration for a given interface type, or to destroy to remove a custom setting. For example, setting zxr10PerfDataUpdatePeriodRowStatus to active after configuring both the checkpoint type and update value finalizes that custom refresh-interval entry.
