6 Tools to Manage Network Configuration for All Your Devices

For any seasoned network administrator, configuring devices is as easy as pie, and many could likely do it even in their sleep. However, despite the seeming simplicity of configuration, the reality is that with the advanced operating systems of modern networking equipment, such as Cisco’s IOS, there are numerous options, which in turn create a lot of room for errors. The larger the network, the more potential there is for mistakes. Fortunately, there are tools like SolarWinds Network Configuration Manager, ManageEngine Network Configuration Manager, TrueSight Network Automation, and Lan-Secure Configuration Center that can help manage these complexities and reduce the risk of errors.

What if you’d manage a number of devices, wouldn’t you like them to have similar configurations? They wouldn’t be identical but the general options should be the same across all devices. With today’s regulations such as PCI/DSS, SOX, and others, some configurations options are mandatory and must be present on all devices. This is where the best tools to manage network configurations can help and this is what we’ll be discussing today.

The best of these tools will not only ensure that your equipment configurations are normalized, but they will also demonstrate their regulatory compliance. Security is also an important aspect of these tools as hackers often start their attacks by modifying device configurations to gain access to networks. Many network configuration management tools will either protect you from unauthorized changes or at least alert you of them.

We’ll begin by discussing network configuration management. We’ll have a look at what it is and why you need it. Then, we’ll talk about the essential elements of network configuration management tools. While they vary a lot in their feature set, there’s a common base that you can expect to find in every good one. Finally, we’ll jump into the core of the matter and review some of the best tools to manage network configurations.

All You Need To Know About Network Configuration Management

Put simply, any tool which assists administrators with network configuration management can be referred to as a network configuration tool, plain and simple. But what is network configuration management, exactly? Well, it seems like everyone has their own opinion about that. But in reality, there are many elements to network configuration management. First and foremost, those tools are used for documenting and/or somehow preserving device configuration data. Whenever a piece of equipment breaks and must be replaced, it’s much easier to pull its configuration from some archive than to redo it from scratch which can lead to delays and inconsistencies.

Deploying standard device configurations is another place where network configuration management tools can help a lot. Having standard configurations makes maintenance much easier and also helps with troubleshooting. In addition to standard configurations, network configuration management tools will also help with regulatory compliance. Many regulatory frameworks—such as PCI/DSS or SOX—have strict guidelines as to how switches should be configured, what security options must be enabled, etc. Network configuration management tools can assist with device configuration auditing and compliance demonstration.

And while on the subject of auditing, network configuration management tools 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. This could be just an urban legend or a sequence from a movie but is it a risk you’re willing to take? Auditing networking device configuration for unauthorized changes is not just for the paranoids among us, it can also be useful for verifying that change management processes are followed.

Typical Elements Of Network Configuration Tools

While network configuration management tools vary greatly, they all share at least a common set of basic features. They 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 most network configuration management tools.

First, the tool should offer a way to establish a configuration baseline. It should also handle device configuration backups. It should provide some form of configuration monitoring and alert administrators or managers of unauthorized changes. Most good network configuration management tools will also provide a way to rollback changes easily and last but not least, it should assist in distributing firmware updates, although this last element is less common.

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