The filter specification table contains specifications for the IP filtering module. Rows are indexed by a single integer index (filterSpecIndex). The fltGlobalIndexNext object is used to determine the next index value. Each row points to a sequence of rows (statements) in the filterStatementTable. When any row in that sequence is modified, created, or removed, the fltSpecVersion1 and fltSpecVersion2 objects must be incremented. Rows are created by assigning fltSpecIndex and setting fltSpecRowStatus to 'createAndGo'. All columnar objects in this table have default values, so no objects other than the index value need be set to create a row. Rows are removed by setting fltSpecRowStatus to 'destroy'. When a row is removed, each row in filterStatementTable with the same fltSpecIndex is automatically removed.
