Build the config, block by block
Tick what the switch needs, answer the questions, and the config on the right follows as you type: paste-ready, in the order the switch wants it, each block with why it is there and the show commands that prove it worked. Every build is checked against the command set of the release you pick and pasted into a sandbox switch before you see it. What you type stays in this page, same as the checker.

Open in the sandbox hands the config over in this browser's storage and swaps the shared secret for the bench ClearPass's own (192.0.2.10, cppm-lab-key), so the devices on the bench can authenticate. The checker deletes what it is handed as soon as it reads it.
