We rely so heavily on technology today that any network problem can halt productivity and cost your company if the issue isn’t dealt with quickly. Prevent losses and eliminate frustration with a comprehensive network diagram of your space. You’ll be able to pinpoint the issue with one glance at Lucidchart and take off to resolve it.

Network diagrams display the components of a computer or telecommunications network, including routers, firewalls, and devices, and show how those components interact. They vary greatly depending on the type of network, but you will likely want two diagrams, a logical network diagram and a physical network diagram.

Benefits of a logical network diagram

First, illustrate how information flows through your network with a logical network diagram. These diagrams could describe:

• Wide area networks (WAN)
• Local area networks (LAN)
• Virtual private networks
• DSL network connectivity
• AWS network architecture

You can make this network diagram as detailed as you want—it could include just a broad overview or consolidate all of your information, such as IP addresses, in one spot.

Benefits of a physical network diagram

When you experience network issues with your office or data center, we’re not always talking about a breakdown somewhere in the recesses of the Internet. We’re often talking about physical objects that are no longer functioning as they should. Network engineers need a visual presentation of this space to understand where the source of the problem may lie.

Within Lucidchart, you can create a physical network diagram to solve this type of issue. An effective network diagram could display:

• Wi-Fi access points and their corresponding channels/frequencies
• Wi-Fi coverage mapping to avoid cross-talk between domains
• The location of phones, computers, printers, and other devices
• A layout of the server rack
• Labeled ports to show where computers and other devices connect to the server

The more information you provide within the diagram, the better prepared you will be to solve network issues during network troubleshooting.

Other benefits of network diagrams

Aside from offering a simple visual for pinpointing possible issues, network diagrams provide many other benefits for your company. Using network diagrams can help with:

Planning network updates

Anytime you need to make a change, refer back to your network diagram. For example, do you need to add more devices to your network? Figure out where you have port space available, how this device will connect to the Internet, etc.

Keeping track of PCI compliance

If you collect credit card information from customers, make sure you have the proper firewalls and access control measures in place and have followed the requirements for physical security. Learn more about how you can make network diagrams that help you prove and maintain compliance by meeting criteria outlined in PCI compliance standards.

Creating network documentation

Creating network diagrams are an essential piece of documentation that every department should have. Hosting your network documentation in a central location like Lucidchart ensures teams have access the current state of your network as they address network problems during network troubleshooting, as your department responds to audits, during security reviews, and more.

Onboarding

Everyone should be on the same page as far as how the network functions and how all the elements connect. Bring new IT engineers up to speed quickly with thorough documentation in Lucidchart, and in the apps you already frequently use, such as Confluence, Jira, Microsoft, Google, Slack, and more.

Provide remote assistance for other offices

You may not always have IT teams located in every office. When a branch of your business experiences network problems, IT teams can leverage your up-to-date network diagrams to provide remote assistance, quickly resolving the network issue from afar. You can even use a floor plan to map out where all your physical equipment is located so it can be easily found it in the case of an issue, ultimately helping incident response teams understand how the office is set up, without needing to be there, all while following compliance regulations.

Lucidchart solutions for network diagramming

As we’ve hinted, Lucidchart is a dynamic options as you look for logical and physical network diagramming solutions. The following features within Lucidchart will strengthen your network diagrams so you have enough information at your disposal to diagnose and troubleshoot errors.

Network diagram templates and industry-standard symbols

Lucidchart offers templates for generic network and server rack diagrams. If none of the templates match the framework of your office or data center, Lucidchart still has all the shapes you need so you don’t have to completely start from scratch. Open our shape libraries for clean, simple symbols to represent your computers, servers, firewalls, etc.

If you are building a physical network diagram, we also have floor plan templates for recreating your office space.

Features to customize the view of your network diagram

Use Layers and shape Actions to make your diagram’s elements easier to see and find.

• Layers: If you add too much information into a single, tight spot of your diagram, it can become less effective and hard to understand. With Layers in Lucidchart, you can separate different types of information, such as Wi-Fi coverage mapping or additional details about each port. Just toggle the layers and find the exact information you need. You can also create and toggle between current and future state versions of your network diagram when you're hoping to make changes.
• Shape Actions: If your network diagram involves multiple pages, you can use hotspots to show the user where to look next. Shape Actions in Lucidchart allow you to link to other pages within the document, hyperlink to external resources (perhaps to Confluence pages or Jira tickets), and even show, hide, or toggle layers.

Real-time collaboration and sharing features

Your ability to diagnose and troubleshoot issues later on depends on the accuracy of your network diagram now. Confirm that you have complete, correct information with these collaborative features:

• Real-time editing with multiple users
• Chat and comments
• @mention notifications
• Support for all operating systems and devices

As your company grows and as you add to your network, you can make changes to your diagram in Lucidchart for all collaborators to see. Any changes you make will be reflected in the apps where you've already added your network diagrams. For example, changes will be made to Confluence wiki pages where you've embedded diagrams, or in Jira issue tickets as you create and resolve incidents.

Using Lucidchart as your go to network troubleshooting tool allows you to access the information you need in one central location, while keeping team members up to date as you work through network problems together over Slack, Microsoft Teams, and the other apps you're already using. Simply include your Lucidchart network diagrams where you're already working, like Atlassian, so your IT teams have the information they need, when they need it.
