What Is Network Configuration Management?

Network configuration refers to the initial process of defining a network’s operation, flow, and controls—essentially maintaining and arranging the information associated with all your network’s components. Network configuration management, then, is the ongoing process of overseeing the setup and maintenance of all network devices, as well as the software and firmware installed on them. It encompasses the discovery of devices, the monitoring of device configuration and status, and the maintenance of inventory.

At the core of this process is the network configuration management database. When something goes wrong and the network needs repair, changes, or upgrading, the network admin will look to the database for the necessary information, so they can make an informed choice as to the best course of action. The database stores the IP address and location of every hardware device, in addition to data pertaining to programs, versions, updates, and default settings.

It’s critically important for enterprises to have a robust network configuration management system. A network configuration manager enables admins to stay on top of any changes made to device settings, and how those changes might impact the overall security of the network—certain changes could threaten your users’ privacy or create a weak point in your network. In addition, the firmware installed on devices has the potential to make them vulnerable to attack. Network configuration management software track all the firmware on your devices and issue updates.

What to Look For in a Network Configuration Manager

Automating the management of your network configuration will reduce time spent on repetitive yet necessary tasks, coordinate changes throughout the network, and help ensure your network runs at peak performance. A good network configuration manager will minimize configuration errors and optimize the security of your network. It should be able to carry out the following key tasks:

  • Set a baseline for configuration
  • Roll back changes to earlier configurations
  • Archive the details of network configuration changes
  • Distribute updates to firmware
  • Create backups of configuration snapshots

In addition, you can choose to look for network configuration tools with the ability to:

  • Distribute configuration updates in bulk
  • Undertake compliance audits
  • Manage firmware patches

Best Network Configuration Management Tools

When it comes to automating the management of your configurations, a huge array of tools and programs are on the market. Some are paid, while others are free and open-source, and choosing among them isn’t simple by any means. A paid solution doesn’t necessarily offer good value, and a free solution isn’t necessarily functional.

I’ve reviewed the leading network configuration tools and compiled this guide to help you choose the right one for your business. I’ve included free as well as paid premium tools, to suit the full range of budgets. However, the free tools available tend to be designed for small network rather than large business or enterprise use.

  1. SolarWinds Network Configuration Manager

SolarWinds Network Configuration Manager (NCM) is a feature-heavy, intelligent, and market-leading program.
