A switch you can type on
A modelled AOS-CX access switch, in the page, with a fake ClearPass behind it. It answers ? and Tab the way the box does, keeps a running config, and the devices on the bench authenticate or fail against whatever you configured. Pick a lab and it sets the bench up and checks your work; Free play is a blank 6200F. It is a model, not the real switch: the output shapes follow the CX CLI, the wording is mine, and anything the lab did not need is not in it.
Where the labs come from
The six NAC labs follow the Zero to NAC track on one bench: a 6200F and a ClearPass that answers the way the lab says it does. Run the same steps on real gear and the show commands will look familiar, with the box's own wording.
