This read-write RowStatus value controls creation and modification of an N+1 backup entry, with the MIB noting that only creation and modification are supported operations for this row, not deletion via the standard destroy mechanism described elsewhere. An admin uses this to create a new N+1 backup relationship between a failed port and its designated backup port, or to modify an existing one. For example, an admin would set this object appropriately when first defining the failed-port and backup-port identifiers for a new N+1 protection relationship.
