You can schedule a scan to run at a set frequency. This is particularly useful on an active network.

1. Go to Environment > Assets & Groups > Schedule Scan > Asset Discovery Scan.

2. Click Schedule New Scan towards the right.

3. Type a name for the new scan.

4. Type the target network or networks to scan. You can type a unique CIDR (x.x.x.x/xx) or a CIDR list separated by commas, CIDR1, CIDR2, CIDR3, ..., up to 14 addresses.

   Warning: You will not be able to save the scan if you try to add more than 14 CIDR addresses.

5. Select a deputy from the list.

6. Select the advanced options according to your network capacity. For a description of these options, see Advanced options for asset scans.

7. Select scan frequency. The options are Hourly, Daily, Weekly, or Monthly.

   The next scan runs an hour, a day, a week, or a month, respectively, after the previous scan has finished.

8. Click Save.

Note: The results of scheduled asset discovery scans do not appear in the web interface. USM Appliance adds the new assets automatically and updates existing ones if it identifies any new properties.
