Discover everything connected to your network from devices, servers, VMware virtual machines, deployed software, LANs, port-to-port connectivity and other resources automatically or on-demand. With WhatsUp Gold's network device discovery, you gain an understanding of your network from top to bottom and focus on keeping it running securely and at peak performance.
Map, inventory, and visualize your network topology and interdependencies
Document and track all your IT assets with enhanced inventory discovery
Troubleshoot connectivity issues with Layer 2 Trace and IP/ Mac Finder tools
WhatsUp Gold uses a number of innovative Layer 2/3 discovery technologies–including ARP, SNMP, SSH, Virtual Infrastructure Management, IP addressing, ICMP and LLDP in combination with vendor-proprietary mechanisms – to discover everything connected to your network and build a complete and accurate picture of network devices and their port-to-port connectivity. Full or partial discoveries can be scheduled to run automatically or run on-demand.
WhatsUp Gold auto-generates integrated Layer 2 and 3 network maps that give you full visibility into physical, logical and virtual connectivity, including IP and VLAN-specific information. It dynamically updates its maps as changes occur in the network. Maps are easy to customize and manipulate so you can view your network the way you want. Learn more about network maps.
Save precious time by using WhatsUp Gold to search and discover how devices are connected. With detailed device views, you can quickly zero-in to find out what’s connected to what. And, with built-in tools such as Layer 2 Trace and IP/ MAC Finder, WhatsUp Gold offers the industry’s fastest approach to finding the location and validating connectivity of any device on the network.
WhatsUp Gold provides comprehensive network inventory and configuration information – supporting the reporting/ documentation needs of your internal business process (such as ITIL) and regulatory requirements like PCI DSS, SOX, FISMA and HIPAA. Since you can easily export this information in CSV or Excel formats, your entire team will know exactly what resources are on your network, where they are and how they are connected at all times – even when your network grows, your office moves or datacenter resources get consolidated.
Gather, filter and export a wide variety of inventory and configuration information across networking devices and systems.
Address Resolution Protocol (ARP) is a communications protocol used to map a layer 3 (network layer/IP) address to a layer 2 (data link/MAC) address. ARP builds and updates a dynamic database of IP to MAC mappings called the ARP cache/table. These entries typically configured with short Time-To-Live (TTLs) of ideally 15 minutes to ensure accurate information is constantly available.
The SNMP protocol allows the discovery engine to query detailed device information from each SNMP-enabled device. SNMP is the predominant network discovery protocol, with a majority of network devices being SNMP-enabled. The SNMP manager software, present in the network management solution, uses UDP polling to identify SNMP-enabled devices in the network.
Secure Shell is an UNIX-based command line interface used to securely access remote systems, and query them for detailed device information. It is the recommended protocol in a network discovery tool to discover UNIX and Linux systems.
IP addressing is a major technology used in a network discovery tool since almost all network devices from routers, printers, managed switches, workstations and servers are assigned with IP addresses. Using these addresses, WhatsUp Gold can map the network interconnections, as well as gather detailed information about the devices.
Link Layer Discovery Protocol (LLDP) is a vendor-neutral one-way protocol, working at Layer 2 to facilitate exchange of device information between directly connected devices. Each LLDP enabled device transmits device information (device type/ID, port ID) on to its directly connected neighbors, which then store this information on management information databases (MIBs).
The Internet Control Message Protocol (ICMP) allows the discovery engine to test whether a particular IP address is active and responding on the network. ICMP is another protocol used to discover networks, and is widely used through the Ping network discovery tool. Ping sends out ICMP echo queries, and automatically discovers devices on a network by analyzing the echo replies from them.

Network discovery is the process of discovering and mapping devices on your network. Discovering network devices is the first step in mapping and monitoring your networked infrastructure. Keeping an up-to-date network inventory of hardware and software assets, physical and virtual resources, deployed patches and topology maps is only possible via automatic Layer 2/3 discovery tools.
Device discovery tools simplify the discovery process by using a variety of discovery protocols to discover and collect information about:
