Protocol The authentication protocols to use:
• CHAP—Challenge-Handshake Authentication Protocol.
• PAP—Password Authentication Protocol.
• MS-CHAP—Version 1 of the Microsoft version of CHAP (RFC 2433).
• MS-CHAP-2—Version 2 of the Microsoft version of CHAP (RFC
2759).
• EAP—Extensible Authentication Protocol.
You may select one or more authentication protocols, as required.
Options The authentication options to use:
• Call In—When selected, authentication is performed on incoming calls.
• Call Out—When selected, authentication is performed on outgoing
calls.
• Call Back—When selected, authentication is performed on callback.
• One Time—When selected, one-time passwords are used for
authentication. One-time passwords are considered highly secure since
each one is used only once. When deselected, one-time passwords are
not used.
Note AAA authentication must be enabled in order to use one-time
passwords. See AAA Policy Page, page K-87. One-time passwords
cannot be used with CHAP.
• Optional—When selected, allows a mobile station in a Packet Data
Serving Node (PDSN) configuration to receive Simple IP and Mobile IP
services without using CHAP or PAP.
When deselected, mobile stations must use CHAP or PAP to receive Simple
IP and Mobile IP services.
