Network Configuration Guide
Document topology, IP schemes, and firewall rules so any engineer can follow, even at 2 AM. Try it in Elium.
The Network Configuration Guide Template helps you document your network setup (from VLAN configurations to firewall rules) in a format any engineer on your team can follow. When something breaks at 2 AM, the answer is in the guide, not in someone's head. It's the documentation that pays for itself the first time you need it.

What is it?
A network configuration guide is a structured document that describes the design, addressing, routing, and security configuration of a network segment, giving engineers the reference they need to manage, troubleshoot, and modify infrastructure without reverse-engineering the setup.
Network configuration is the foundation that all IT services depend on. When it is undocumented, every change carries risk: engineers guess at IP ranges, duplicate firewall rules, or break routing because they cannot see the full picture. A structured template captures the design intent alongside the technical detail. Each guide covers the same sections (topology, addressing, routing, security) so any engineer can navigate any site’s configuration using a familiar format.
Who should use this template?
This template is for teams responsible for network infrastructure:
-
Network Engineers: document configurations so colleagues can manage and modify infrastructure without the original designer
-
IT Support Teams: reference network guides when troubleshooting connectivity issues or onboarding new services
-
Security Teams: audit firewall rules and access policies against documented baselines
-
IT Managers: maintain visibility into network architecture across all sites for capacity planning and compliance
How to create this template in Elium
-
Open the Template Builder: Go to your profile menu and select the Template Builder tab, or click “+ Create” and choose “Create a new template”.
-
Set the scope: Choose an icon, enable the template, and decide whether it applies platform-wide or to specific spaces (e.g. your Network Infrastructure or IT Operations space).
-
Add structured fields: Click “Field” to add metadata: text fields for segment name and site location, tag fields for technology stack and criticality level, a user field for guide owner, and date fields for last verified and next review. Mark segment name and guide owner as mandatory.
-
Build the guide structure: Use the “+” button to add content blocks: an image block for topology diagrams, table blocks for IP addressing and firewall rules, text blocks for routing and security configurations, and a text block for monitoring details. Add placeholder prompts (e.g. “Which VLANs are assigned to this segment?”).
-
Preview and save: Review the template layout, then save. Network engineers can now document configurations consistently, and you can apply it to existing content in bulk.
How AI helps
Capture faster. Paste switch configurations or firewall exports into Elium’s AI. It identifies the key parameters (subnets, VLANs, routes, and rules) and then drafts a structured guide that the engineer validates rather than documenting each setting manually.
Retrieve smarter. An engineer asks Elium’s AI: “What is the VLAN assignment for the guest wireless network at the Brussels office?” The AI returns the VLAN ID, subnet, DHCP scope, and firewall rules from the relevant guide.
Why teams use Elium for this
Network documentation decays faster than most IT knowledge. Firmware upgrades, capacity changes, and security patches modify configurations continuously. When documentation lives in spreadsheets or personal notes, it drifts out of sync within weeks. Elium keeps network guides where engineers work: structured templates enforce consistency, and AI search returns the right configuration from a question.
VINCI Energies, with 97,000 employees across 61 countries, centralised IT knowledge in Elium. With 4,000+ articles and 1,000+ daily users, their engineers reference documented configurations rather than relying on memory or undocumented tribal knowledge.
Common questions about network configuration guides
A network configuration guide documents the topology, addressing, routing, and security settings of a network segment in a structured format. Without one, engineers reverse-engineer configurations during troubleshooting, changes carry unnecessary risk, and audits cannot verify whether the current state matches the intended design.
A complete guide includes metadata (segment name, location, technology stack, owner, review date) and body sections covering topology diagrams, IP addressing with VLAN assignments, routing protocol and gateway configurations, firewall rules and security policies, and monitoring targets with alerting thresholds.
Documented network configurations reduce troubleshooting time because engineers see the full picture before making changes. They improve change management because modifications start from a documented baseline. They support compliance because auditors verify configurations against documented security policies rather than inspecting devices directly.
Start with the topology: draw the physical and logical layout before documenting details. Use tables for IP addressing and firewall rules. They are easier to scan than paragraphs. Include actual values from production, not generic examples. Assign an owner and update the guide after every change, not quarterly.
A network diagram shows the visual layout: devices, connections, and segments. A configuration guide adds the detail: IP addressing, routing, firewall rules, VLAN assignments, and monitoring settings. The diagram answers “what connects to what?” The guide answers “how is it configured and why?”
