Configuring the VPDN Username and Password
The Security Appliance uses a username and password pair to authenticate to the AC. To
assign a username and password pair for PPPoE authentication, you use the following
command:
vpdn username username password password
NOTE ISPs that use CHAP or MS-CHAP may refer to the username as the remote system
name and the password as the CHAP secret.
NOTE The username specified must be the username that has already been associated
with the VPDN group specified for PPPoE (using the vpdn group command).
