As-Built Network Documentation and Topology Diagrams.
As-built network documentation and updated topology diagrams
Part of Network & Security Support. Last reviewed October 2026.
Quick answer
What is As-Built Network Documentation and Topology Diagrams?
As-built network documentation is the record of what was actually installed and configured, as opposed to what was planned. Deploris engineers capture device locations, port connections, addressing, and configurations during the work, then deliver updated topology diagrams and tables your operations team can use immediately for support and audits.
WHAT THE WORK COVERS
What As-Built Network Documentation and Topology Diagrams includes.
- 01Physical topology diagrams showing devices, uplinks, link speeds, media types, and the room, rack, and rack unit location of each device
- 02Logical diagrams for layer 2 and layer 3, including VLANs, trunks, routing domains, VPN tunnels, and WAN circuits
- 03Port maps and patch schedules that tie switch ports to patch panel ports, wall outlets, and connected devices
- 04IP address and VLAN tables with subnets, gateways, DHCP scopes, and management addresses as built
- 05Rack elevation drawings and dated photos of racks, cable management, and labeling
- 06Configuration backups and a record of device model, serial number, firmware version, and license state
- 07A deviations list comparing the as-built state to the design, and optional updates to your CMDB or IPAM when you give us access
HOW WE DELIVER IT
How it is delivered.
- 1
Collect your baseline
We ask for the existing diagrams, address plan, and naming standard, and agree the formats and tools you want the final documents delivered in.
- 2
Capture during the work
Engineers record port connections, labels, serials, and photos as devices are installed, rather than reconstructing them from memory after the visit.
- 3
Reconcile with configuration
Captured data is checked against exported device configurations, LLDP or CDP neighbor tables, and ARP or MAC data to confirm the diagrams match the running network.
- 4
Deliver and file
You receive the updated diagrams and tables in your chosen formats, with a deviations list, and we load them into your documentation system where access allows.
INPUTS AND OUTPUTS
What you provide and what you receive.
You provide
- Existing network diagrams, IP plan, and naming and labeling conventions
- Preferred file formats, such as Visio, draw.io, PDF, or spreadsheets
- Read access to device configurations or permission for our engineers to export them
- Access details for your CMDB, IPAM, or documentation repository if you want records loaded directly
You receive
- Updated physical and logical topology diagrams in the agreed formats
- Port maps, patch schedules, and IP and VLAN tables for the equipment in scope
- Rack elevations and dated photos of the installed equipment and labeling
- Configuration backups and an asset list with serial numbers and firmware versions
- A deviations list showing where the build differs from the approved design
WHEN IT FITS
When this is the right deliverable.
Your network diagrams date from several refreshes ago, and the team that built the original network has moved on.
You need handover documentation your operations or managed services team can accept before they take over support of a new site or campus.
An audit or insurance review asks for current network records, and you want evidence of port-level connections and device inventory that supports your compliance evidence.
WHERE WE DELIVER
Delivered in 75+ metros across 11 countries.
Local, vetted engineers deliver this work on site across the United States and Western Europe, coordinated by one engagement manager.
