A network diagram is like the Blueprint of a building since it reveals how the network is built. But contrary to its construction counterpart, it’s often performed after the network has been built as a way of documenting how it works and its multiple components interconnect. Network diagrams are one of the most crucial troubleshooting tools. They will often allow you to pinpoint the source of problems. To create fantastic diagrams, you need the appropriate tools. Luckily, there are lots of specialized tools out there which you may use. And today, we’re reviewing some of the best network diagram mapping and topology software.
We’ll start off by talking The need for system diagrams. As you’ll see, they are multiple and various needs can call for different kinds of tools. And talking about the type of tools will be our next order of business. Even though there are a lot of distinct kinds of tools, in the network diagram standpoint, we have divided them into basically two types. Finally, well reveal exactly what the most effective tools we can find are. We’ll start off with the mapping and topology tools as they’re often the most fascinating and follow up with simpler drawing tools.
The Demand For Network Diagrams
So, why do we Want network diagrams ? I think everybody has his own reason but some are more prevalent than others. First and foremost, any platform is simply as great as its documentation. When the machine is a computer network, a diagram is perhaps the best type of documentation an individual can have. Diagrams may include a lot of information. A normal network diagram will tell you what each piece of gear is, how everything is interconnected and it will often contain more details like IP addresses or other configuration parameters.
When something is Wrong with the community, a diagram is often one of the primary tools you’ll use. A network diagram ought to immediately allow you to determine what devices are on the road, giving you a starting point for troubleshooting.
Some will assert That they don’t need diagrams as they have a mental picture of how the system is installed. While this is often true, it’s only to a certain degree. And as time goes by, we often overlook the smaller details. While we may still have a fairly good mental picture of the way that network we deployed 5 decades back is made, we possibly don’t recall all the minute details. Furthermore, other administrators might have done some changes since we last worked on it.
Documentation is Really the only way to keep an eye on everything and, when it comes to systems, a diagram is most likely the very best type of documentation an individual can have. But programs, such as most other things in existence, do evolve and changes are regularly applied. Devices are additional, circuits are updated, configurations are altered. These changes must be documented. Like the system it represents, a network diagram should be a constant work in progress and great care has to be taken to keep this current. There is nothing more frustrating than trying to debug network issues using outdated diagrams.
Different Kinds of Tools For Different Purposes
Network diagram Mapping and topology tools vary considerably. This is partially because of the varying demand of network administrators. But what’s more, there doesn’t seem to be any sort of consensus on what they are. To some vendors, they are simply drafting aids that substitute the drafting tables, squares, rulers, and mechanical pens of yesteryear. To others, they’re innovative applications that will automatically discover devices and plot their interconnections, leaving minimal function for the consumer. Others make it a comprehensive management system with several innovative capabilities. For our purposes, we will split them into two fundamental kind of tools. Mapping and topology tools on a single side and drawing instruments on the opposite hand.
Network Mapping And Topology Tools
These tools will Typically do much more than just help you draw network diagrams. Some may use SNMP and other protocols such as CDP to poll your devices and discover their interconnections. They’ll use this information to automatically build a graphical representation of your system.
These tools are Rarely perfect and their drawings will often need some degree of manual screening.
The more advanced Tools within this class are more management systems compared to documentation systems. They’ll permit you to monitor devices’ status and functionality and, in some instances, permit you to handle them right from the mapping and topology tool.
Network Drawing Tools
The following Kind of tools is “plain” network drawing tools. In contrast to the tools in the last class, these tools will only help you with the real drawing of your system maps. They are basically the automatic model of a drafting table and pair of drawing tools. That does not mean they are not helpful. Actually, whoever has completed manual drafting previously and now does it on a computer will inform you how more functional it is.
Some tools have Lots of additional features beyond straightforward drafting. Some, for instance, will let you script actions when clicking certain objects on your drawing. An intelligent administrator could turn these into a management system. For instance, a system map could be configured to ensure clicking an object opens a terminal link to it.
The Very Best Mapping And Topology Tools
Thus, let’s see Exactly what the ideal mapping and topology instruments are. Some of the tools we found will just let you map the topology of your system while others can practically be considered complete tracking tools. They do have one thing in common, they can automate the process of communicating your system.
has assembled a Strong reputation within the area of network management tools. Its flagship product, the Network Performance Monitor is among the best SNMP monitoring tools and the company is also well-known for its own free tools.
The SolarWinds Network Topology Mapper (NTM) is an evolution of LanSurveyor, a former tool also from SolarWinds. This instrument will automatically detect your LAN and/or WAN and generate comprehensive, easy-to-view system topology diagrams that incorporate Layer 2 and Layer 3 information. NTM utilizes an innovative concept known as topology databases. This allows many different maps to be built from one scan of the community, thereby saving time and resources.
Another Fantastic feature of That the SolarWinds Network Topology Mapper is that it will automatically keep its diagrams current. It is going to regularly re-scan the system looking for changes in topology and new devices. It may even help with network security as it will detect rogue devices that might have been linked to the network.
Furthermore, the tool Can aid with PCI/DSS and other regulatory compliance requirements and can be used as a networking equipment inventory management system.
The SolarWinds Network Tech Mapper can cost you $1 495 that isn’t much considering all of it really does. And in the event that you’d like to try the product before purchasing it, a free 14-day evaluation can be obtained. Intermapper
From Help Systems is available for Windows, Mac, and Linux. This instrument will auto-discover all your physical and virtual gear and place it on a map showing all the interconnections. All that’s left is for you to customize the maps to fulfill your real-life network. It’s possible, as an example, change the design, customize the icons or change the wallpaper images.
But Intermapper Is not just a topology mapping tool, it’s also a fairly superior monitoring solution. It’s live color-coding and animation to highlight the status of your apparatus. As an instance, the colour of device icons will move from green (all good) to yellow (warning) to orange (alert) to red (down). Similarly, animated traffic indicators will alert you of any section where traffic exceeds a predefined threshold.
Intermapper is Available in a free version that is limited to 10 devices. For larger setups, you can choose between annual subscription or permanent licenses with costs varying according to the amount of devices. A free 30-day trial can be offered.
NetProbe is another product that provides Way more than just network topology mapping. In fact, it calls itself a real time device tracking tool. And this is really what it’s. This tool will monitor any network-attached device in real time.
This tool’s graphic Layout includes a whole lot more than only the devices. As an example, alerts and trackers will also be integrated into it. And in order to allow for simple, quick, and neat example of the tracked environments, all drawing components are kept as straightforward as possible.
Another Fantastic feature of This tool is your apparatus auto-detection. The tools will automatically scan your system to find devices and upload them into the diagrams but it doesn’t stop there, it will also automatically add alerts and charts that are pertinent to every device.
NetProbe is accessible Four license levels in the free standard license which only allows for eight devices to the Enterprise permit which is good for as many as 400 devices.
4. Network Notepad
That barely made it in this category. Essentially, it’s merely a drawing instrument but some add-ons are readily available to give it some of the”intelligence” of other tools in this list. Let us find out what it has to offer.
First, the tool has all The characteristics you’d expect from a drawing tool such as multi-page diagrams, custom shapes, grouping and locking–that allow you to combine existing shapes to create new ones, auto-alignment, and naturally, templates.
However, as we said, Network Notepad really shines when you begin using its add-ons. The most interesting is the CDP Neighbor Tool, an auto-discovery utility. This tool utilizes the Cisco Discovery Protocol (CDP) to automatically record devices interconnections. You merely should right-click an item in your diagram, select”Discover Neighbors”, and it will utilize SNMP to extract information from the device’s CDP table about what’s linked to the object and the interconnection interfaces. Then you click on the”Paste” button to add the discovered items to your own diagram.
Accessible as a feature-reduced Freeware variation or as a Professional version which you may purchase for 18 British Pounds once the 30-day trial period expires.
The Finest Network Drawing Tools
The following Products are simpler–well, a number of them are actually quite complex–tools which are meant to be a replacement for the fantastic old drafting table and building tools. They’ll enable you to draw maps of the network but you will have to provide the wisdom and draw on the interconnections and relationships between devices yourself. Some of the packages on our list are almost full-fledged CAD tools while some are highly specialized in drawing on networks.
5. Microsoft Visio
Business drawing, Visio–or Microsoft Office Visio, as it’s officially called–was the de facto benchmark for a while.
The main attribute Of Visio is the usage of items stencils as the key elements. There are collections of stencils for all kinds of use, including several for network gear or network logos. What’s more, some manufacturers–such as Cisco, for example–offer downloadable Visio stencils that you can use on your system diagrams.
Pricing for Visio Is complex and varies in the event that you buy as an Office part or a standalone version. It’s accessible as an online-only option beginning at $5/month or as a locally-installable software starting at $15/month. These rates are for a one-year commitment.
Our listing as it’s the free tool that most closely resembles Visio. If you’d like that the Visio look-and-feel without spending huge sums of money, Dia may be just the tool for you. Dia is based on Visio albeit using a slightly reduced feature set. But the majority of the Visio attributes missing in Dia are not required for basic network diagramming.
Networking gear Templates are, of course, available as are many more templates. Diagrams made with Dia can be saved in a customized XML format and can also be exported to several other vector or bitmap formats such as EPS, SVG, XFIG, and PNG. Dia is released under the GPL license and its available for free and will run on Linux, Unix, OS X, and Windows. ConceptDraw Pro
is just another business Drawing tool which handles network diagrams pretty nicely. Its user interface is quite intuitive and if you have any experience with goods in the Microsoft Office package, you will feel right at home with this program.
This is a strong Package which may be utilised to create a complete assortment of business images and documents. The tool has tens of thousands of available stencils and hundreds of templates for quick diagramming. Of course, all the required templates and stencils for network diagrams are contained.
ConceptDraw Pro is an Interesting alternative to Visio also it will both save and read Visio files perfectly. But the tool won’t only replace Visio, in addition, it has some effective presentation features, which makes it an alternative to PowerPoint too.
ConceptDraw Pro is
Different from the other entries on our list. It is only accessible as an internet web-based tool. All diagram creation and editing are done inside your own browser on Lucidchart’s website. Another unique quality of the software is that you start new diagrams by viewing one of the pre-configured diagrams that can be found and customizing it for your need. This makes for very quick drawing.
This tool uses regular HTML5 so it is going to operate on any modern browser. Additionally, it has some great collaboration features, allowing teams to work on diagrams. Furthermore, all data is encrypted for your security and everything is automatically backed up and will always be available.
Lucidchart is available A free trial of version is available, as are staff variants for a number of users.
Last on our list Is LanFlow, a dedicated network diagramming solution. This tool will enable you to create all sorts of LAN, Internet, computer and telecommunications network diagrams. Your creativity and inspiration are the only limitations to the amount of information you may include in your LanFLow diagrams. You can use it to document a system, display cabling and wiring, and communicate flows and processes.
The application has both 2D and 3D networking symbols, outline logos, and some simple block diagram symbols. You can also add your own clip-art to the tool to represent your particular network equipment. If all you need is to record networks, LanFlow is possibly the easiest and fastest solution available.
