TERMINAL SERVERS
Statement 3 enables RADIUS authentication on PORT number 1. If
AUTHENTICATION is enabled globally, as with statement 4, the port can
only be logged in to by a user with a valid user name and password. A valid
user name is a user name that has an entry in the RADIUS server “users” file
in the following format:
andy Password= “abcdef”
User-Service-Type = Login-User,
Login-Host = 111.222.111.222,
Login-Service = Telnet
Figure 4-31. Enabling RADIUS Authentication.

PPP authentication protocols.
The two authentication protocols that may be employed on a PPP link are:
