The method used for authenticating the PPP peer is selected here. The possi-
ble values are:
None (def) - No attempt is made to authenticate the PPP peer.
Radius - The Express L128/L128T will act as a RADIUS client and
authenticate the PPP peer using the RADIUS server. The Radius
server parameters must be set up properly for this to work.
Connection List - The Connection List profile is used to authenticate
the PPP peer.
See Configuration/Connection List on page 63 for more information
on authenticating.
