> # About Validating a RADIUS Server

> As of Cisco SAN-OS Release 3.0(1), you can periodically validate a RADIUS server. The switch sends a test authentication to the server using the username and password that you configure. If the server does not respond to the test authentication, then the server is considered non responding.

> Note For security reasons we recommend that you do not use a username that is configured on your RADIUS server as a test username.

> You can configure this option to test the server periodically, or you can run a one-time only test.
