An entry in the port classifier rules table. When a row is created/deleted , a corresponding row (where portClassifierInvSequenceNumber equals portClassifierActionSequenceNumber) is automatically created/deleted in the portClassifierInvTable. When a row in this table is in active(1) state, no objects in that row can be modified except for portClassifierActionSequenceNumber. A row can be deleted unconditionally. When a row is deleted at the portClassifierTable all the corresponding rows in this table are automatically deleted as well.
