AI296 Version 9.8x User’s Guide
Link Configuration: PPP Authentication Configuration
6-58

RAS Option

Description
This menu item configures the method AI296 uses to obtain ID and password
information for a link. The following options are available:
zDisabling RAS causes AI296 to use local ID and password information to validate
the ID and password sent from a remote device.
zEnabling 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.
zEnabling 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.
zEnabling 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.
zEnabling 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.
