ADTRAN Express L128T S User Manual page 87

• When originating an outgoing call:
• Express L128T S/T uses PPP method configured in
Configuration/Security/PPP.
• Authenticatee's (i.e., WAN far-end device) username is
compared to the profile used to dial.
• Authenticating with RADIUS:
• When Configuration/Security/Authentication is set to
Radius, authentication is performed by a RADIUS server on
the near-end LAN.
• The Express L128T S/T uses the DEFAULT Connection List
profile for all other parameters not supported by RADIUS
attributes.
• RADIUS attributes currently supported are: framed ip,
framed netmask, framed ipx network, framed routing,
framed compression, and idle timeout.
2. The Express L128T S/T 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 L128T S/T for
authenticating itself with the PPP peer.
• If the Configuration/Security/Authentication parameter is
set to Connection List or RADIUS, the Express L128T S/T
will wait until the PPP peer is authenticated before
authenticating itself with the PPP peer (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 L128T S/T 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 PAP,
CHAP, or EAP is used.
