For instance you might be required to re-program the VLAN configuration of a switch port in the instance a VoiP system has been physically moved.īenefits of automated network mapping tools and software Information such as the exact port of the switch where the device is connected is very important.

This means that you will know if something goes offline and where the issue has occurred.įor example Brocade/Ruckus ICX switch from the above example going offline is going to impact all the VoiP systems connected to it.Īdditionally, if someone decides to move something on the network, you will also see this reflected on the network topology map in real-time. What the network mapping tool does is show you exactly what is on the network and how it is interconnected in real-time.

20 other devices connected to the rest of the 28 ports available on the Cisco Switch.

A Cisco Meraki WiFi Access Point (powered through the Cisco Switch, and which connects office WiFi clients such as Laptops, mobiles and touch-panels.

A Brocade/Ruckus PoE switch (which powers and connects VoiP systems).

Then comes the Cisco SG350 Switch (SW1) which provides the main connectivity to the rest of the network, including:.

The Domotz Agent is directly connected to the firewall.

The Watchguard M270 firewall is connected to the main gateway.

Here is an example of a network topology map using the Domotz remote network monitoring software. “A network map displays in a visual format, all the devices on a network, how they are interconnected as well as the transport layer.” ( Techopedia ) The tool is designed so that it can elaborate this data, create inferred relationships (such as devices routed through WiFi Access Point), and present the devices and how they are connected to each other in the form of a topology map. Regardless, of the methodology adopted to collect raw data out of the networking devices, the information is sent back to the network mapping software. This provides the information required to understand which MAC addresses are “reachable” through a specific network port of managed switches. Unfortunately, many devices don’t currently support either of these protocols.Īnother methodology is based on the information which can be retrieved through SNMP on networking devices compliant to RFC-4188.

IEEE standard protocols, such as Link Layer Discovery Protocol (LLDP) or proprietary ones, such as Cisco Discovery Protocol (CPD) are often enrolled to collect information about how devices are connected to networking equipment that supports those protocols. To automatically create a network map, devices are usually primarily identified by MAC address and different methodologies are used to locate where devices are and how they are connected to each other. How automated network mapping tools and software work Or there is an automatic generation of the map through the usage of a paid plugin (UVExplorer Pro)

(Free 21 day trial – with no credit card). All features cost only $19/month for monitoring and automatically mapping unlimited endpoints on a network.

Domotz: Affordable remote network monitoring software which includes automated network topology mapping features.

Here is a quick overview of some of the free and paid manual and automated network mapping tools available today. Most of these network mapping tools are not automated. There are many free network mapping tools available for MSPs, integrators and IT professionals. Network mapping is the first step in managing and securing a network. Manual vs Automated Network Mapping Tools Yet only a select few of these softwares automatically create and keep a network topology map updated with real-time data. Most network mapping software allows for manual creation of the network’s topology and connections between devices.

The best starting point to understand how to secure and manage a network, is by using automated network mapping tools to understand all the devices on a network and how they are interconnected. In addition, devices on the same network are very often segmented across multiple VLANs to allow segregation of data flow or for security purposes. Networks are also becoming more distributed too, a single network can span across continents and even countries. As more devices and IoT systems are attached to a network, the more difficult it becomes to understand exactly how a network is set-up and how devices are attached to each other. There is no doubt that networks are becoming more complex.
