> # Allowing Users to Specify a RADIUS Server at Login

> By default, an MDS switch forwards an authentication request to the first server in the RADIUS server group. You can configure the switch to allow the user to specify which RADIUS server to send the authenticate request by enabling the directed request option. If you enable this option, the user can log in as username@hostname, where the hostname is the name of a configured RADIUS server.

> ## Detailed Steps

> 1. Expand Switches > Security > AAA, and then select RADIUS.
