For IPV6 addresses, it is actually only possible to use single addresses, not ranges. Remember to use braces, around the address.
To add a scan setting
You can add multiple scan settings for Assets Discovery to execute. This could be useful if you wanted to run scans or different parts of your system at different intervals.
To add a scan setting, select the '+' button at top.
To delete a scan setting
- To delete a scan setting, select the 'x' button at top.
- In the Delete Entry screen, select Yes.
To test a scan setting
Once you have configured a scan setting, you can test the scan without running a full execution of Assets Discovery. The results are displayed immediately, and a more detailed Evaluation Report is saved to your \logs\ directory.
- Select Start Evaluation-Report.
- Enable or disable the fast checkbox:
- If enabled, Assets Discovery tests your scan settings using ICMP pings only.
- If disabled, Assets Discovery tests your scan settings by trying each individual connection.
- Select Start to begin the test scan. When the scan is complete a success message will be displayed that includes the location of the saved Evaluation Report.
