Table 5-3. Remote Node Profile Menu Fields for Leased Line Applications (continued)
Field
Outgoing: Authen
(*for backup line only)
Description
This field sets the authentication protocol used for
outgoing calls.
Your Prestige supports two authentication protocols:
PAP (Password Authentication Protocol) and CHAP
(Challenge Handshake Authentication Protocol).
l
PAP sends the user name and password in plain
text.
l
CHAP scrambles the password before it is sent
over the wire.
Generally speaking, CHAP is more secure than PAP;
however, PAP is readily available on more platforms.
The recommendation is to use CHAP whenever
possible. Turning off the authentication is STRONGLY
discouraged.
Options for this field are:
l
CHAP/PAP - Your Prestige will try CHAP when
CHAP is requested by the Remote Node or PAP
when PAP is requested by the Remote Node.
l
CHAP - use CHAP only.
l
PAP - use PAP only.
