Mapping a Flat Network

---

If you have one network with no subnets, or you want to create subnets manually, you can use the ICMP option.

The Scan tool automatically detects the network devices within a specified range of IP addresses and creates a single map. You specify a range of IP addresses to be scanned, and WhatsUp Gold polls each address in the range. If WhatsUp Gold finds an active network device in the range, it creates an icon for the device.

You can also enable the scan so that it identifies particular device types. For information on how to do this, see "Customizing Device Types". A scan can also identify the network services (such as FTP, HTTP, SMTP) on each network device.

To start a scan:

1. Select an existing map or create a new map window.
   • To create a new map, from the File menu, select New Map Wizard. In the New Map wizard, select the Discover and Map Network Devices option on the first screen and select Discover your network using ICMP on the next screen.
   • To add devices to an existing map, select the map, then from the Tools menu, select Discover Devices and select Discover your network using ICMP on the next screen.
2. Edit any of the IP Address Scan options. Click Help for a definition of each option. Click Next to continue.
3. Select the Services you want to scan for, and click Next.
4. The scan begins and when it has completed, it provides you the opportunity to finalize which devices you want to appear on the map. Click Finish to complete the wizard.
   
5. From the File menu, select Save or Save As to save the map.
6. see "Tips for Making a Map Easier to Read".

Results of the Scan

When you use the Scan tool as described above, WhatsUp Gold scans the range of IP addresses. For each active IP address it finds, it lists the address

(Under the right conditions, the Scan can also recognize particular device types. For more information, see "Scanning and Mapping a Device".)
