Controlling the Discovery Scan Range
The Network Device Discovery operation identifies intelligent devices on your network by sending a message to specified IP addresses then waiting for a reply. By default, the operation collects and analyzes data from the devices installed on the subnet to which your Console belongs. Use the Scan Range tab to specify all the addresses you want the operation to ping for information and to specify any addresses you want to exclude from the scan.
To specify the IP ranges you want to scan for devices:
1 In the Site Management folder, click the Device Discovery Configuration operation, and select the Scan Range tab.
2 To add a search range to the list, click the upper Add button, and enter an IP range in the Add Values dialog.
You can enter the range in the form 90.0.10.128 - 90.0.20.255 or you can use a wildcard. For example, 192.168.31.0 - 192.168.31.255 is the same as 192.168.31.*.
3 If you do not want to scan all the IP addresses in the ranges you specified, click the lower Add button and enter the exclusion ranges in the Add Values dialog.
4 When you have specified all the IP addresses you want to scan, click OK to save your changes. The filters are applied when the scan next runs.
