•When originating an outgoing call:
-Express L128/L128T uses PPP method configured in
Configuration/Security/PPP.
-Authenticatee’s username is compared to profile used to dial.
•Authenticating with RADIUS:
-When Configuration/Security/Authentication is set to Radius, authentication is performed by the RADIUS server.
-The Express L128/L128T uses the DEFAULT Connection List profile for all other parameters not supported by RADIUS attributes.
-RADIUS attributes currently supported are: framed ip, framed net- mask, framed ipx network, framed routing, framed compression, and idle timeout.
2.The Express L128/L128T as the authenticatee:
•When answering an incoming call:
-If the Configuration/Security/Authentication parameter is set to None, the DEFAULT profile’s Tx Username and Tx Password are used by the Express L128/L128T for authenticating itself.
-If the Configuration/Security/Authentication parameter is set
to Connection List or RADIUS, the Express L128/L128T will wait until the PPP peer is authenticated before authenticating itself (except when CHAP or EAP is used). If CHAP or EAP is used, the username transmitted by the PPP peer’s authentication challenge packet is looked up in the Connection List. If found, the Express L128/L128T responds with the profile’s Tx Username and Tx Password parameters. If not found, the DEFAULT profile’s Tx Username and Tx Password parameters are used.
•When originating an outgoing call:
