Network+ lab 5 of 27

VLANs and trunking between switches

Split an office into department VLANs across two switches. You build the VLAN database, assign data and voice VLANs to access ports, join the switches with an 802.1Q trunk on an unused native VLAN, and manage both switches through a management SVI.

Run this lab

It needs Lite: its 6 nodes are set to 6 vCPU and 5,632 MB in total. That fits the free demo too.

In your workspace: Shared, then CompTIA Network Plus N10-009 guided labs, then 05 - VLANs and trunking between switches

The scenario

Harbour Logistics' head-office floor has Sales and Accounts staff on both sides of the building, each side with its own switch. Today everyone shares one flat network, so Accounts' traffic (payroll) reaches every Sales PC and a broadcast storm on one side hits the other. You'll split the floor into VLANs, carry them between the switches on a trunk, and give each switch a management address.

The PCs already have their addresses. There's no router yet (lab 06 adds one), so only hosts in the same VLAN can talk.

What you’ll practise

  • Create VLANs and name them in the VLAN database
  • Configure access ports with data and voice VLANs
  • Configure an 802.1Q trunk with a restricted allowed list and an unused native VLAN, with DTP off
  • Configure a management SVI and test it across the trunk
  • Show that VLANs are separate broadcast domains and recognise a native VLAN mismatch

The tasks

  1. Build the VLAN database
  2. Configure the access ports, data and voice
  3. Build the trunk between the switches
  4. Add the management SVI
  5. Prove the VLANs are separate

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 05 - VLANs and trunking between switches 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.
