Use from RADIUS Configuration mode to configure the secret for a RADIUS
preauthentication server.
The server secret is a text string used by RADIUS to encrypt the client and server
authenticator field during exchanges between the router and a RADIUS
preauthentication server. The router encrypts PPP PAP passwords using this text string.
The default behavior is no server secret.
Example
host1(config-radius)#key gismo
Use the no version to remove the secret.
NOTE: The preauthentication request fails if you do not specify a key for
the preauthentication server.
See key
Use to assign an AAA profile to static and dynamic, multilink and nonmultilink PPP
interfaces.
For more information about how to use this command, see "ppp aaa-profile" on page 66.
Example
host1(config-if)#ppp aaa-profile preAuth
Use the no version to remove the AAA profile assignment.
See ppp aaa-profile
Use to configure an AAA profile to support RADIUS preauthentication.
During preauthentication, the router sends an Access-Request message to a RADIUS
preauthentication server to obtain an LLID for a subscriber. In response, the
preauthentication server returns the LLID in the RADIUS Calling-Station-Id [31] attribute
of an Access-Accept message.
Example
host1(config-aaa-profile)#pre-authenticate
Use the no version to remove preauthentication support from the AAA profile.
See pre-authenticate
