Description: Each filter is represented by a row in the anueNtoFilterDefTable and a row in each of the filter history and filter statistics tables that logically augment that table. Unlicensed ports are not filters so they are not represented by rows in the filter tables. Dynamic filters and standalone port filters are each represented by a single row in the filter tables. A network or tool port group containing n port members is represented by n+1 rows in the filter tables. A bidirectional port has two filter definition rows. One row models its role as a network port and another models its role as a tool port. A bidirectional port group containing n port members is represented by 2*(n+1) rows in the filter tables.
