You can set a manual accept mode option for a discovery filter to redirect any discovered systems that match the filter to the IP Manager’s Pending Devices list. That way, you can view the systems on the Pending Devices list and then select which of them should be added to the modeled topology. The procedure to specify the manual accept mode option is described in the IP Manager User Guide.
In addition, you can set a system limit option for a discovery filter to limit how many discovered systems that match the filter are added to the topology. The procedure to specify the system limit option is described in the IP Manager User Guide.
