Network+ lab 17 of 27

Network documentation and configuration management

Inherit an undocumented network and bring it under control. You build an asset inventory, discover the cabling with CDP and LLDP, document it on the devices, find a duplicate IP address with your address list, then back up configurations to a server, archive every save automatically and roll back an unapproved change.

Run this lab

It needs Lite: its 5 nodes are set to 5 vCPU and 3,072 MB in total. That fits the free demo too.

In your workspace: Shared, then CompTIA Network Plus N10-009 guided labs, then 17 - Network documentation and configuration management

The scenario

You've taken over the Harbour Logistics depot network from a contractor who left no documentation. All you have is the management subnet, 10.99.0.0/24, and an address plan (IPAM) from head office. Over this lab you'll build the inventory, discover the cabling, label everything, reconcile the addresses with the plan, and put the configurations under control with backups, automatic archives and a rollback plan.

Address plan (IPAM)Device
10.99.0.1R1
10.99.0.2R2
10.99.0.10H1, the TFTP backup server
10.99.0.11SW1 (Vlan99)
10.99.0.12SW2 (Vlan99)

What you’ll practise

  • Build an asset inventory from show version and show inventory
  • Discover neighbours with CDP and LLDP and record a cable map
  • Keep an IP address inventory and use it to find a duplicate address
  • Back up configurations to a TFTP server and archive every save
  • Compare running and startup configurations and roll back to a baseline
  • Describe change management and configuration management

The tasks

  1. Start the backup server
  2. Build the asset inventory
  3. Discover the cabling with CDP and LLDP
  4. Write the cable map onto the devices
  5. Reconcile the addresses with IPAM
  6. Back up and archive the configuration
  7. Catch an unapproved change and roll it back

The Lab Tasks pane has the scenario, these tasks, the checks to run, hints and the full solution.

How to open this lab

  1. Sign in to your workspace at lab.cloudlabbox.com.

  2. In File Manager, open Shared, then the folder CompTIA Network Plus N10-009 guided labs.

  3. Open 17 - Network documentation and configuration management and start its nodes, then open Lab Tasks for the scenario and the steps.

The lab is read-only. You can start the nodes and configure the devices, but changes to the topology can’t be saved. To change it, rebuild it in your own folder.
