8 Best Network Configuration Management Tools and Software

8 Best Network Configuration Tools and Software

Setting up network equipment can occasionally pose a challenge. In reality, the difficulty lies not so much in the initial configuration, but in its maintenance and standardization. I remember starting a new job and finding that each of the numerous network switches had slightly different configurations, making problem-solving a major headache.

In today’s regulatory environment, with standards such as PCI/DSS and SOX, it’s more crucial than ever to have a robust configuration management process in place. For this purpose, Network Configuration Management tools and software like SolarWinds Network Configuration Manager, ManageEngine Network Configuration Manager, and WhatsUp Gold Network Configuration Management Add-on can greatly assist in this task.

Moreover, solutions like ConfiBack and TrueSight Network Automation can further streamline the process, ensuring that your network configuration is not only standardized but also compliant with all necessary regulations.

This is where Network Configuration Management software and tools can come in handy. The best of these tools will not only ensure that your configurations are normalized but they can also be used to demonstrate their regulatory compliance. There’s also a security element to these tools. It is all too common nowadays to see hackers start their attacks by modifying device’s configuration to gain access to networks and many tools will either protect you from unauthorized changes or at least alert you of them. For all these reasons, we’re going to be sharing our list of the top network configuration tools and software.

We’ll start off our journey by discussing network configuration tools and software. We’ll have a look at what they are about, how they operate and why you need them. We’ll then introduce some of the main features found in these tools. Tools vary a lot in their feature set but there’s a base that you can expect to find in every tool. With all that behind us, we’ll jump into the core of the matter and review some of the best network configuration tools and software we could find.

Network Configuration Tools And Software – What They’re All About

Network configuration software that assists administrators with network configuration management. That’s simple enough. But what is network configuration management, exactly? Answering this question is somewhat harder as it seems that everyone has their own opinion about that. There are several elements to network configuration management. First and foremost, it has to do with documenting and/or somehow preserving device configuration data. Whenever a network switch breaks and needs to be replaced, we’d rather pull its configuration from some archive than to redo it from scratch which can lead to delays and inconsistencies.

Configuration management also helps with deploying standard device configurations. This makes maintenance much easier and also helps with troubleshooting. But in addition to standard configurations, configuration management will also help with regulatory compliance. Many regulatory frameworks—such as PCI/DSS, just to name one example—have strict guidelines as to how switches should be configured. Configuration management will help you audit switches and demonstrate their compliance.

And while on the subject of auditing, configuration management processes can also assist with auditing switch configuration for unauthorized changes. We’ve all heard of malicious users trying to gain access to corporate networks by first modifying networking devices configuration to put backdoors in place. Whether this is a true risk or an urban legend is open to debate but we’re never too careful and auditing device configuration for unauthorized changes is a common configuration management task. And even if you’re not that paranoid, it’s also useful for ensuring that change management processes are followed.

What To Look For In Network Configuration Management Tools Software

While network configuration tools which are also referred to as network configuration management software vary greatly, they all share at least a basic set of features. Those are considered to be essential features and each tool will include them even though their implementation could vary from tool to tool. Here are some of the common features that you should find in a network configuration tool.

It should provide a way of establishing a configuration baseline. It should also handle configuration backups. As stated before, it should provide some form of configuration monitoring to alert administrators of unauthorized changes. A good network configuration tool software should also provide a way to rollback changes easily and last but not least, it should assist in distributing firmware updates.

In addition to these essentials, the best network configuration tools will also include extra features. Among the most common—and the most useful—standards compliance auditing is a great feature. Bulk configuration updates, as well as firmware patch management, are also among the most useful optional features.

The Best Network Configuration Tools

We’ve compiled a list of the best network configuration tools. Our main selection criterium was that the tools include at least all the basic features. Many products go far beyond that and include not only all the optional features we mentioned but even more than that. This is not a sorted list and don’t assume that a tool’s position is an indication of its value as compared to the others. All the tools suggested here are excellent tools that we wouldn’t hesitate to recommend. Picking one that suits you best will likely be a matter of personal preference. Your choice could be guided by a unique feature of a tool that particularly appeals to you.

ConfiBack backups need to be started manually but you can schedule them to take place on a regular basis The tool also helps with detecting unauthorized changes albeit through a manual process. You need to compare two backups of a device’s configuration manually using a diff command. Diff will find every difference between the two files, thereby highlighting any line that has changed. It is then up to you to determine if the change is legit or not

That’s pretty much all you’ll get with ConfiBack. It is a very basic product but then again, it might be enough for your need. And its price just can’t be beaten.

5. rConfig

Next on our list is a tool called rConfig. This interesting tool has limited features but it works very well. It will auto-detect all your networking devices and back up their configurations into text files. Backups can be run manually or in a scheduled fashion. One feature we found useful is the grouping of devices into categories. It allows administrators to carry actions either on individual devices, on devices within a category or on all devices. Verification and auditing of configuration unauthorized changes is a manual process, much like it was with ConfiBack.

rConfig can be used to quickly push standardized configurations to devices either individually or in categorized groups. Standard configuration from the file store can be pushed out to devices. This network configuration management software also provides some compliance auditing functionality. Policies matching specific compliance requirements or your own corporate practices can be set in rConfig. The Configuration Compliance Manager which is part of the system can then verify your configurations against the set policies and demonstrate their compliance.

rConfig is available in a free community version or in a  pro version with free support and bug fixes at just under 500 Euros per year. It only runs on CentOS and RedHat Enterprise Linux.

6. Net LineDancer

Despite its unusual name, Net LineDancer, which often simply called NetLD, is a great tool from vendor LogicVein with all the features that you would expect from a configuration manager. This tool can manage thousands of devices through automated processes. The product will initially find all your devices and take a snapshot of their configurations, establishing a baseline. This baseline can then be used to identify changes to each device’s configuration.
