Configure FreeRADIUS access for a network device

Open the FreeRADIUS console in nuLAB and select Clients.

Register the router with its address and the shared secret used by the router.

Add a lab user in Users so the server has an identity to authenticate.

On the router, use the named RADIUS group in the SSH login method list.

Connect from the client and verify that the lab user reaches the router terminal.

Try an incorrect password and confirm that SSH denies the login.

Open the authentication log to check both outcomes for the same router.

Reopen the lab and confirm that the client and user entries are still available.
