Usage guidelines
PPP authentication includes the following categories:
• PAP—Two-way handshake authentication. The password used is in plain text.
• CHAP—Three-way handshake authentication. The password is in cipher text.
• MS-CHAP—Three-way handshake authentication. The password is in cipher text.
• MS-CHAP-V2—Three-way handshake authentication. The password is in cipher text.
You can configure several authentication modes simultaneously.
In any PPP authentication mode, AAA determines whether a user can pass the authentication through a
local authentication database or an AAA server. For more information about AAA authentication, see
Security Configuration Guide.
If you configure the ppp authentication-mode command with the domain keyword specified, you must do
the following:
• Authenticate the peer by using the specified ISP domain.
• Use an address pool associated with this ISP domain for address allocation (if necessary).
