: the authentication method which can be radius, local, or none.

: the name of the server group.

For PPP authentication method of AAA, refer to Chapter 57 “AAA and RADIUS 
Configuration”. If PPP authentication method of AAA is not specified on the 
interface, please use the default authentication method.

You finish the fundamental PPP configurations after performing the tasks 
described in Sections 1.2.2 through 1.2.4 and can proceed to Section 1.2.5 to 
start configuring the optional PPP parameters.

By default, PPP accounting is disabled.

The following PPP negotiation parameters can be configured:

Time interval between negotiation timeout During PPP negotiation, if the response 
message of the peer is not received within this time interval, PPP will retransmit 
the message. The timeout interval ranges from 1 to 10 seconds.

For some negotiation parameters of NCP such as the configuration of local IP 
address and the IP address assigned to the peer, refer to Part V “Network 
Protocol”. For example, the 

 command can be used 

to ask the peer to assign IP address for the local, while the 

command can be used to designate the local to assign IP address for the peer.

Perform the following configuration in interface view.

By default, the timeout interval is 3 seconds.

1 Configure client

Suppose PPP has been encapsulated on local and remote interfaces. If the local 
interface has no IP address while the remote interface has one, you may configure 
the local interface to allow it to negotiate an IP address using PPP and accept the 

Configure PPP authentication 
method of AAA at the interface

ppp authentication-mode { chap | pap } [ 
call-in ] [ scheme { default | 
scheme-name } ]

Configure a PPP accounting scheme 
list on the interface. RADIUS 
accounting is also supported.

ppp accounting scheme { default | 
scheme-name }

Cancel accounting of PPP user at the 
interface
