Link Configuration: PPP Authentication Configuration

RAS Option

This menu item configures the method AI296 uses to obtain ID and password 
information for a link. The following options are available:

z

Disabling RAS causes AI296 to use local ID and password information to validate 
the ID and password sent from a remote device.

z

Enabling RADIUS causes AI296 to use the ID and password information 
configured in the RADIUS server to validate the ID and password sent from the 
remote device.

z

Enabling RADIUS with fallback causes AI296 to attempt to use the ID and 
password information configured in the RADIUS server to validate the ID and 
password sent from the remote device. If neither of the RADIUS servers respond, 
AI296 uses the local ID and password (configured in the PPP Authentication 
Menu) for validation.

z

Enabling TACACS+ causes AI296 to use the ID and password information 
configured in the TACACS+ server to validate the ID and password sent from the 
remote device.

z

Enabling TACACS+ with fallback causes AI296 to attempt to use the ID and 
password information configured in the TACACS+ server to validate the ID and 
password sent from the remote device. If neither of the TACACS+ servers 
respond, AI296 uses the local ID and password (entered in the PPP 
Authentication Menu) for validation.



Notes: When connecting to a remote PPP device, ensure that the PPP 

authentication timeout on that device is set to a minimum of 30 seconds. If 
the network latency is high, set that value to a higher number of seconds.



The TACACS+ server used must support version 1.78 or later of the 
TACACS+ protocol.
