JNCIS-ENT lab 2 of 17

VLANs and trunks with native and voice VLANs

Split two floor switches into staff, guest, voice and management VLANs. You carry them over an 802.1Q trunk, put management on an untagged native VLAN, prove that VLANs isolate traffic, and prepare a desk port for an IP phone with a voice VLAN and LLDP-MED.

Run this lab

It needs Standard: its 6 nodes are set to 12 vCPU and 14,336 MB in total.

In your workspace: Shared, then JNCIS-ENT JN0-352 guided labs, then 02 - VLANs and trunks with native and voice VLANs

Run it on Standard from £5 a day

The free demo can’t run it: it has 6 vCPU and 8 GB, and this lab’s nodes need 12 vCPU and 14,336 MB together. Every lab plan includes every guided lab.

The scenario

Ashby Freight's office has a switch on each floor, joined by one cable. Staff and guests must be kept apart, IP phones are about to arrive, and the network team wants to manage both switches over their own VLAN.

VLANIDSubnetPorts
STAFF1010.10.10.0/24SW1 ge-0/0/1 (PC1), SW2 ge-0/0/1 (PC3)
GUEST2010.20.20.0/24SW1 ge-0/0/2 (PC2), SW2 ge-0/0/2 (PC4)
VOICE3010.30.30.0/24Phones on the staff desk ports (with LLDP-MED)
MGMT9910.99.99.0/24Native (untagged) on the trunk; SW1 irb.99 10.99.99.1, SW2 irb.99 10.99.99.2

The trunk between the switches is ge-0/0/0 on both, and must carry all four VLANs. The PCs are already addressed.

What you’ll practise

  • Create VLANs and assign access ports
  • Configure 802.1Q trunks and choose which VLANs they carry
  • Configure a native VLAN and explain when untagged frames are used on a trunk
  • Configure a voice VLAN with LLDP-MED on an access port
  • Verify VLAN membership, tagging and isolation

The tasks

  1. VLANs and access ports
  2. The trunk
  3. A native VLAN for management
  4. A voice VLAN for IP phones

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 JNCIS-ENT JN0-352 guided labs.

  3. Open 02 - VLANs and trunks with native and voice VLANs 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.
