Discover and Map Network Devices
The Discover and Map capability creates a map from information on your computer - or on the network to which your computer is connected - by reading network files and identifying devices listed in the files. These files can include a hosts file, the Windows registry, and Windows network information. Discover and Map can also find devices by reading SNMP information on the network or by scanning a range of IP addresses.
To use the Discover and Map capability:
- From the File menu, select New Map Wizard to view the following dialog box.
- Select Discover and map network devices, and then click Next. The Discover Devices screen appears.
- Select the parameters you want to use to create the map.
Discover your network with SNMP SmartScan. Reads SNMP information on your default router to identify devices on your network and also identifies and maps subnets within your network. Use this option to map a hierarchical network, if your network is SNMP enabled. The Discover Devices wizard will display additional options for scanning with SNMP.
Discover your network using ICMP. Scans a range of IP addresses and maps the devices that respond to a message sent via the Internet Control Message Protocol (ICMP). Use this option to map a single network that does not contain subnets (all devices will be displayed on one map.) The Discover Devices wizard will display additional options for the scan.
Discover devices from your Network Neighborhood. If your computer is connected to a Microsoft Windows network, WhatsUp Gold scans the network and creates an icon for each device it finds. (This can take a few minutes, depending on the size of your network.)
Import devices from your registry. Reads the Windows registry
to find devices that are referenced in the TCP/IP, Microsoft Internet Explorer, or Netscape Navigator configurations, then automatically adds the devices to the map.Import devices from a hosts file. Reads the hosts file on the local system and creates an icon for each network device.
- Click the Next button. Depending on the Discover options you selected, WhatsUp Gold does the following:
- If you selected Discover your network with SNMP SmartScan, it displays the "SNMP SmartScan" dialog box and asks where do you want the SNMP SmartScan to start. Modify any text boxes as needed. Click Next to proceed. To change the default values, see "Mapping a Hierarchical Network".
Note: To make sure you scan only those devices in your own network, you can use the Scan Depth and Limit scan to IP class of root device options. Also, the scan will stop if it comes to a network for which it does not know the SNMP Communities name.
- If you selected Discover your network using ICMP, it displays the "IP Address Scan" dialog box with default values filled in. Click Next to proceed. To change the default values; see "Mapping a Flat Network" for more information.
- If you selected Discover devices from your Network Neighborhood, it displays the "Network Neighborhood Scan" dialog box and asks for you to pick the Domain Names you want to include in the scan. Select the desired domains and click Next to proceed.
- If you selected Import devices from a hosts file, the "Host File Import" dialog box appears and asks what host files do you want to import. Use the browse button if you want to select a different host file. Click Next to proceed.
- If you selected Import devices from your registry, the TCP/IP Service Scan" dialog box appears and asks which services do you want to scan for. Select the services for which you want to scan, and make any other changes you want. Click Next to proceed.
- Reads the network files, locates devices and displays them in the "Scan Results" dialog box. It asks which of these devices do you want to appear in the map(s). They ALL have check marks defaulted with them; only keep check marks on the devices you want to appear in the map. Click Finish and the map is created.
- From the File menu, select Save or Save As to save the map.
