About Enabling MSCHAP

</h1>
<a name="wp1080247"> </a><p class="pBody">
By default, the switch uses Password Authentication Protocol (PAP) authentication between the switch 
and the remote server. If you enable MSCHAP, you need to configure your RADIUS server to recognize 
the MSCHAP vendor-specific attributes. See the <a href="cradtac121.html">&quot;About Vendor-Specific Attributes&quot; topic</a>. <a href="cradtac138.html#wp1080260">Table&#160;30-1</a> 
shows the RADIUS vendor-specific attributes required for MSCHAP.
