Enabling MSCHAP Authentication
Microsoft Challenge Handshake Authentication Protocol (MSCHAP) is the Microsoft version of CHAP.
You can use MSCHAP for user logins to a Nexus 5000 Series switch through a remote authentication
server (RADIUS or TACACS+).
By default, the Nexus 5000 Series switch uses Password Authentication Protocol (PAP) authentication
between the Nexus 5000 Series switch and the remote server. If you enable MSCHAP, you need to
configure your RADIUS server to recognize the MSCHAP vendor-specific attributes (VSAs). See the
"Using AAA Server VSAs with Nexus 5000 Series Switches" section on page
the RADIUS VSAs required for MSCHAP.
