When originating an outgoing call:

-Express XL/XLT 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 XL/XLT 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 XL/XLT 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 XL/XLT for authenticating itself.

-If the Configuration/Security/Authentication parameter is set

to Connection List or RADIUS, the Express XL/XLT 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 XL/XLT 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:

-The dial-out profile Tx Username and Tx Password are used regardless of the PPP peer’s username received if CHAP or EAP is used.

Authentication/Tx Method

Write security: 2; Read security: 3

This parameter specifies how the Express XL/XLT is to be authenticated by the PPP peer. There are four possible selections. See Security/PPP on page 58 for an explanation of the three PPP standard authentication types.

None (def) - The connection will not allow the PPP peer to authenticate it.
