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 60-6. 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.
Authenticate Using AAA authentication settings for the PPP connection:
• PPP Default List—Defines a default list of methods to be queried
when authenticating a user for PPP. Enter the names of one or more
AAA server group objects (up to four) in the Prioritized Method
List field, or click Select to select it. Use the up and down arrows
in the object selector to define the order in which the selected
server groups should be used. If the object that you want is not
listed, click the Create button to create it.
The device tries initially to authenticate users using the first
method in the list. If that method fails to respond, the device tries
the next method, and so on, until a response is received.
Tip After you create the default list for one PPP connection, you
can use it for other PPP connections on this device.
• Prioritized Method List—Defines a sequential list of methods to be
queried when authenticating a user for this PPP connection only.
Note Leave this field blank to perform authentication using the local
database on the router.
PAP Authentication settings
Username The username to send in PAP authentication requests. The username is
case sensitive.
