🛠 Project 07 — Network Documentation Package¶
Type: Design / documentation Modules: 02 (Infrastructure & Documentation) Difficulty: ⭐⭐
🎯 Objective¶
Produce the documentation package a technician would need to operate and troubleshoot a network — physical and logical diagrams, a rack elevation, an IP/asset inventory, a labeling scheme, and a change record.
Document a real network you have access to (home/lab), or the fictional Bright Retail office from Project 05.
📦 Deliverables¶
🔹 1. Physical network diagram¶
Show actual devices, ports, cable runs, and locations. Include MDF/IDF, patch panels, switches, APs, and the demarc/entrance facility.
🔹 2. Logical network diagram¶
Show IP addressing, subnets/VLANs, gateways, and how traffic flows (not physical cabling).
🔹 3. Rack elevation (rack diagram)¶
Document each device's U position in the rack (e.g., firewall U42, switch U40, patch panel U38, server U34–35, UPS U1–4). Total the rack units used.
🔹 4. IP / asset inventory (IPAM sheet)¶
A table of assigned addresses:
| Device | Role | IP | Subnet/VLAN | MAC | Location | Firmware |
|---|---|---|---|---|---|---|
🔹 5. Labeling scheme¶
Define a consistent scheme for cables, jacks, patch-panel ports, and racks (e.g., IDF2-PP1-P14 = IDF 2, patch panel 1, port 14). Explain how it speeds troubleshooting.
🔹 6. Change record + rollback plan¶
Write one change request for a realistic change (e.g., replacing the core switch), including reason/scope, risk, implementation steps, rollback plan, and approval line.
🧰 Tools¶
- Diagrams: draw.io / diagrams.net (free), Lucidchart, or Visio.
- Tables: Markdown or a spreadsheet.
✅ Verification Checklist¶
- Physical and logical diagrams are separate and each shows the right kind of information.
- Rack elevation totals the U used and lists every mounted device.
- IPAM sheet has no duplicate IPs and covers gateways/servers/infrastructure.
- Labeling scheme is unambiguous and consistently applied on the diagrams.
- Change record includes a rollback plan.
🚀 Stretch Goals¶
- Capture a performance baseline (interface utilization at a normal time) to compare against later.
- Add an SLA summary for the Internet link and define your MTTR target for a switch failure.
