3-38 Express 4110/4120 User Manual 61200176L3-1
• When originating an outgoing call:
• Express 4110/4120 uses PPP method configured in Configura-
tion/Security/PPP.
• Authenticatee’s username is compared to profile used to dial.
• Authenticating with RADIU S :
•When Configuration/Security/Authentication is set to Radius,
authentication is performed by the RADIUS server.
• The Express 4110/4120 uses the DEFAULT Connection List pro-
file for all other parameters not supported by RADIUS attributes.
• RADIUS attributes currently supported are: framed ip, framed
netmask, framed ipx network, framed routing, framed compres-
sion, and idle timeout.
2. The Express 4110/4120 as the authenticatee:
• When answering an incomin g call:
•If the Configuration/Security/Authentication parameter is set to
None, the DEFAULT profile’s Tx Username an d Tx Pa ssword are
used by the Express 4110/4120 for authenticating itself.
•If the Configuration/Security/Authentication parameter is set to
Connection List or RADIUS, the Express 4110/4120 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
4110/4120 responds with the profile’s Tx Username and Tx Pass-
word parameters. If not found, the DEFAULT profile’s Tx User-
name 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.
