By default, when the local router is authenticated by the peer in PAP mode, both 
the username and password sent by the local router are null.

In the above table, 

simple

 means to send password in plain text and 

cipher

 in 

encrypted text.

When configuring CHAP authentication, if 

username

 of one end is the 

username

 

of the other, and the 

password

 is the same, it is unnecessary that the 

 command is configured in the other end.

By default, the local router name is null.

It is up to AAA to decide whether a PPP user that has undergone the PPP 
authentication can pass the authentication. AAA authentication on a PPP user can 
be conducted at the local or via a RADIUS server.

Local authentication refers to the authentication performed by making use of the 
local user database that contains the users added by using the 

username password { simple | cipher } password 

command. RADIUS server 

authentication refers to the authentication made by using the user database on 
the RADIUS server. The specific configuration commands are shown in the 
following table.
