Lab

Report a problem

Which lab you are in, where you are up to, the device you are on and this build are sent with it. Nothing you have typed in the lab is attached unless you choose to attach it below.

What is it about? What did you expect? What happened instead? Include the current lab state to help reproduce the problem?

This attaches your lab as it stands now — the devices, the cabling and the configuration you have typed — so the problem can be reproduced exactly. Leave it unticked and your report is still sent.

My saved labs

Closed labs keep their work. Opening one makes it active again.

Create a lab with AI

Labbing Hub does not call or host an AI service. Use whichever AI assistant you prefer — your prompt and your conversation stay between you and them, and nothing is sent to Labbing Hub.

Copy the instructions below into your AI assistant.
Describe the lab you want it to build.
Save its reply as a file, then open that file here.

Saved lab kept

This saved lab can't be safely restored with the current version of Labbing Hub. Your saved lab has been preserved. You can start a new lab or remove the saved one.

This lab did not load

Labbing Hub could not open this lab. Nothing has been lost — the lab may have been withdrawn, or renamed, or this link may be out of date.

This lab is open in another tab

A lab runs in one place at a time, so its console output is not split between two tabs. Carry on in the tab you already have open.

To watch several devices at once, open a console window for each of them from the topology.

Lab Paused

This lab was paused after 15 minutes of inactivity so simulated time would not continue while you were away.
