Network Mapping Software That Maps Your Network in Minutes

Finally, you can put down your whiteboard markers and relax while our network mapping software does the network mapping for you. Leveraging a unique multi-level network discovery technique, SolarWinds Network Topology Mapper (NTM) automatically discovers your LAN or WAN and produces a comprehensive, easy-to-view network diagram that integrate OSI Layer 2 and Layer 3 topology data for powerful network visualization.

Top 6 Reasons to Use Network Topology Mapper

  • Network Topology Discovery & Mapping

    Views of network topology, network discover and network mapping capabilities.

    SolarWinds Network Topology Mapper (NTM) is powerful network mapping software that automatically discovers your entire network and creates comprehensive, detailed network maps in just minutes.

    • Automatic discovery of network topology using ICMP, SNMP, WMI, CDP, VMware®, Microsoft® Hyper-V®, and more
    • Generate comprehensive, highly detailed network maps and networks
    • Build multiple maps from a single scan without the hassle of rescanning the entire network
    • Display entire network, network segments, or specific device types on maps
    • Export network diagrams and maps to Visio®
    • Easily modify node details and manually connect the nodes
    • Get a clear picture of what’s connected to a specific node

    SolarWinds® Network Topology Mapper (NTM) automatically discovers every device on the network, including routers, switches, servers, wireless access points (APs), VoIP phones, desktops, and printers. Network Topology Mapper uses industry-standard identification and network discovery methods (ping/ICMP, SNMP v1 - v3, WMI, CDP, VMware®, Microsoft® Hyper-V®, and more) to scan IP address ranges and find nodes. For any SNMPv3 credentials you specify, it uses FIPS-compliant algorithms to encrypt credentials. Now, NTM allows you to automatically save credentials for future network scans.

    Network Topology Mapper’s automatic network topology discovery can identify and scan all the network segments connected to your routers—or you can choose to perform automatic network discovery on specified segments. You simply enter the IP address range(s) and SNMP community strings and SolarWinds NTM automatically starts network discovery.

    Once network nodes are discovered, NTM compiles the information into a cohesive, easy-to-view network diagram with node icons and labels indicating switch port information. In addition, NTM features a standard switch ports report that provides a table of information about all connected nodes. You can also modify node details (node name, node role, and management IP address) and manually connect nodes.

    The comprehensive network topology discovery method of SolarWinds NTM provides a view of the entire network, as well as the ability to limit the view to individual network segments. NTM can automatically display Layer 2 network maps or you can select Layer 3 to display IP topology information on your network diagram. You can even create hybrid network maps containing both Layer 2 and Layer 3 information to get a comprehensive view of your network.

    NTM’s Add Neighbors feature lets you right-click on a node to get a clear picture of what's connected.

  • New Build Many Maps with One Scan


    SolarWinds® Network Topology Mapper (NTM) employs an innovative concept of topology databases. You can scan a big network and build many useful maps without having to rescan, saving valuable computing resources, bandwidth, and time.

    • Build maps on the fly without performing new scans
    • Flip between maps quickly
    • Copy nodes (including their layout) between maps

    To keep your NTM diagrams updated, you can manually rescan or schedule rescans by filtering the types of nodes to automatically add to maps. For example, you can schedule a rescan to only include new routers and switches.

    • You can drag nodes from discovered nodes or shortcuts and drop them on any map. You can also select multiple nodes and groups
    • Spend more of your time making useful maps and less time configuring, scheduling, and waiting on scans

  • Export Network Diagrams to Visio®

    View of network diagram exportation.

    Export network diagrams to Microsoft Office® Visio®, Orion Network Atlas, PDF, and PNG formats with our network diagram software, SolarWinds NTM.

    • Export network diagrams to Microsoft Office® Visio®, Orion Network Atlas, PDF, and PNG formats
    • Auto-populate Visio SmartShapes
    • Schedule updated map exports to Orion® Network Atlas

    Exporting SolarWinds® Network Topology Mapper (NTM) network diagrams into Microsoft ®Visio® format automatically populates Visio SmartShapes® with network discovery data—a huge timesaver!

    SmartShape technology is used to represent network devices, automatically populating each node's Tool Tips with the node's IP address, network name, fully-qualified domain name (FQDN), and more. Network Topology Mapper supports Microsoft Visio 2003, 2007, 2010, and 2013.

    For SolarWinds Network Performance Monitor (NPM) users, Network Topology Mapper gives you the option of exporting network maps to the Orion Network Atlas format for seamless transfer of network node info into the SolarWinds Orion platform. These exports can also be scheduled to update maps in Orion Network Atlas.

    If NTM identifies a new device on your environment, this update will be sent across to Network Atlas (depending on the predefined schedule). You as an admin would have the option to decide if this new node detected would take the form of an Orion node or not.

    NTM also lets you export network diagrams to other common formats such as PDF and PNG.

  • Auto-Detect Changes to Network Topology

    Auto-Detect Changes to Network Topology

    SolarWinds Network Topology Mapper (NTM) automatically detects new devices and changes to network topology with the Network scan software. You can create a do-not-scan list to exclude specific networks or nodes from scans.

    • Detect new devices and changes to network topology
    • Document network changes for regulatory compliance
    • Enter a list of devices to exclude from discovery

    NTM’s scheduled scan feature monitors your network for new devices, changes, and unknown systems. Changes are immediately reflected in your network diagram, ensuring that you always have an accurate, up-to-date record of your network topology. When unknown and rogue systems are identified during scans, NTM alerts you with pop-up dialogues.

    Network Topology Archives for Regulatory Compliance
    NTM’s scheduled scan feature is also ideal for creating archives of your network diagrams as the network topology changes over time, allowing you to automatically maintain documentation for regulatory and troubleshooting purposes.

    Switch Port Connectivity
    NTM can routinely update your network topology map down to the switch port. It accesses managed switches to accurately diagram port connectivity, resulting in a network topology map that illustrates all nodes connected directly to a managed switch.

    Schedule Updated Map Exports to Orion®
    NTM gives you the option of exporting updated network maps to the Orion Network Atlas™.
