About Configuring the Scan Range of IP Addresses

You can configure the scan range of IP addresses:

• Add a new IP address or range.
• Skip an IP address in a range or skip a range.
• Delete an IP address, range or subnet.

Delete IP address

Removes the IP address from the scan. Use when you are never interested in collecting data at that IP address.

Adding IP Addresses or a Subnet to the Scan

You can do any of the following:

• Add IP addresses one at a time if you know a specific IP address that needs to be added to the scan.
• Add one or more ranges to add many IP addresses at once or if you are adding only some in the subnet.
• Add a subnet mask to get everything on the network.

1. In Service Center, click Site Management > Sites.
2. Click the site for which you want to edit the scan settings.
3. Click the Network Discovery tab.
4. In the Network Scan (Local Network) section, click Modify.
5. In the Scan Settings section, click Add.
6. Do one of the following:
   • To add a single IP address to the scan, select the Single option button and type the device IP address in the IP Address box.
   • To add a range of IP addresses to the scan, select the Range option button and type the Start IP Address and End IP Address in the boxes.
   • To add a subnet to the scan, select the Subnet Mask option button. Type the network address in the box, and specify the prefix size in the numbered list. Optionally, type a description in the Description box.
7. Click Save.

Skipping IP Addresses During the Scan

Does not query the IP address. Use when you know IP addresses that you do not want to scan. For example,

• if an auditor is at the customer site and has been given a static IP address, you can skip it because the auditor is not your customer.
• if a range of IP addresses is used for visitors to a company, then this range should be skipped as the devices that use this range are not your customers.

You can skip an individual IP address or a range of IP addresses.

1. In Service Center, click Site Management > Sites.
2. Click the site for which you want to edit the scan settings.
3. Click the Network Discovery tab.
4. In the Network Scan (Local Network) section, click Modify.
5. In the Scan Settings section, click Add.
6. Do one of the following:
   • To skip a single IP address, select the Single option button and type the device IP address in the IP Address box.
   • To skip a range of IP addresses, select the Range option button and type the Start IP Address and End IP Address in the boxes. Type a description, if desired.
7. Select the Skip check box.
8. Click Save.

Deleting an Item from the Scan

1. In Service Center, click Site Management > Sites.
2. Click the site for which you want to edit the scan settings.
3. Click the Network Discovery tab.
4. In the Network Scan (Local Network) section, click Modify.
5. In the Scan Settings section, select the check box for the item you want to remove.
   Ensure that you select an item that is not currently skipped. Selecting a skipped item and clicking Delete returns the item to the scan (essentially ignores the skip rule).
6. Click Delete.
