How to Create a Baseline for Config Comparison in Network Configuration Manager?

In today’s world, manually setting networks is a terrible effort. A big network configuration requires a lot of time and effort. It’s not only about the network configuration for huge enterprises. A manual approach would be unfeasible due to the number of devices linked to the network. Therefore, several development teams have created configuration managers to assist manage your network devices’ config files.

In addition to keeping track of config files in real-time, Solarwinds Network Configuration Manager (download here) offers several more functions.

Network Configuration Manager

With Network Configuration Manager, you can automate network device configuration, saving you time and money. Beyond backups, NCM creates a baseline configuration file for improved network understanding. In addition, network Configuration Manager (NCM) is now integrated with Solarwinds Network Performance Monitor (NPM). So that system engineers are alerted of any illegal modifications, it also monitors your configuration.

Make sure your network has Network Configuration Manager installed before proceeding with this instruction. Thanks to the Orion Platform, installation is quick and easy. Then run the installer from the above URL. The installer explains the rest of the operation. Keep on, and you’ll have the programme running in your network in no time.

What is a Baseline Template?

The baseline template defines the approved configuration files or a subset of them. The configuration baselines evaluate other devices’ configs and alert network managers to any discrepancies. This is useful for network management since it establishes a standard for device settings, assuring network compliance. In addition, when comparing updated configs, you can see what has changed in the config file.

Creating a Baseline

It consists of three steps:

  • Establishing the baseline template’s contents.
  • Designating lines to disregard during config comparison.
  • Assigning the baseline to devices.

There are three approaches to establishing a basic template’s content. First, before making any modifications, promote an existing config to baseline. Second, you may select a file from your server, and third, you can create a baseline and paste the contents in. Let us begin without further ado. Create a baseline by following the steps.

  1. Go to My Dashboards > Network Configuration > Configuration Management to promote a config to baseline. Then, click on a node to expand its configs. You may promote any config to baseline by selecting Promote to Baseline.
  2. You may also use a server file as a baseline. This is done by selecting Configuration Management from My Dashboards. On the Baseline Management tab, select New Baseline. Give the baseline a name and a description if desired (optional). Next, select a file from the server by clicking Browse.
  3. To paste the baseline’s contents, click Paste instead of the Browse option. Then click Save.
  4. Then choose lines to ignore during config comparison. To do so, select one or both of the options: Apply global comparison criteria and Choose lines to ignore.
  5. If you select Apply global comparison criteria, you must first view/edit your comparison criteria.
  6. Finally, click Assign to Nodes to assign the device baseline settings on the New Baseline Config screen.
  7. Then choose the nodes/devices to which the baseline should be applied.
  8. Under Apply To, you may pick which device states the baseline is compared to.
  9. Now click Save to save your choices.
  10. Save your baseline by clicking Save again.

Editing the Baseline

A baseline template allows you to make changes at any time. Go to My Dashboards > Network Configuration > Configuration Management to edit a baseline. So go to Baseline Management and choose the baseline you want to update. You may then adjust the baseline to suit your requirements.

User Questions:

What role does setting a configuration baseline have in network administration?

Proper configuration baselines also increase security because, during their construction, they necessitate a thorough assessment of every parameter. Depending on the use case, they may change a device’s default behaviour to a more secure posture.

What exactly is the baseline setup in the context of networking?

A baseline configuration is a collection of settings applied to a system before it is approved for use in a production environment. A strategy that arose from administrative checklists to guarantee that systems were configured appropriately for their intended purpose is the use of baselines (or starting points).

What is the best way to compare two configuration files?

  • Navigate to Config Management –> Config Archive from the main menu bar.
  • Select a Device Group from the drop-down menu, and then select a device from the table below.
  • By checking the boxes next to two files, you can select them.
  • To compare two options, use the Compare button.

What is the definition of a configuration baseline? Is it true that both are correct?

A configuration baseline is a fixed reference point in the development cycle or a specification of a product agreed upon at a certain time. It serves as a written foundation for describing the incremental change and includes a wide range of product characteristics. Therefore, a configuration baseline is frequently referred to as a baseline in general.

What is a baseline configuration document, and why do you need one?

Documented set of specifications for an information system, or a configuration item inside an information system, that has been formally examined and agreed on at a certain time and can only be altered via the use of change control processes.
