Allowing Users to Specify a RADIUS Server at Login

</h1>
<a name="wp1076510"> </a><p class="pBody">
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 <em class="cEmphasis">username@hostname</em>, where the <em class="cEmphasis">hostname </em>is the name of a configured RADIUS server.
