Cayman 3220-H User’s Guide

Using the Command Line Interface

December 2000

You can use the following commands to specify how your Cayman 
3220-H should respond when it receives an authentication request 
from a remote peer.

The settings for port authentication on the local Cayman 3220-H 
must match the authentication that is expected by the remote peer. 
For example, if the remote peer requires CHAP authentication and 
has a name and CHAP secret for the Cayman 3220-H, you must 
enable CHAP and specify the same name and secret on the Cayman 
3220-H before the link can be established.

set PPP module vccn port-authentication chap-option 

{ on | off }

Specifies whether CHAP authentication is enabled. By default, CHAP 
authentication is turned off. CHAP authentication must be enabled 
before you can enter other CHAP information. If CHAP is turned on, 
it will be the first authentication method offered to the remote peer 
during link negotiation.

If you turn port authentication off and peer authentication on, the 
PPP software still uses the port authentication chap-name and 
pap-name for authentication. As a result, the port authentication 
names for PAP and CHAP must be identical to the peer names for 
your Cayman 3220-H on the remote peer. If you do not configure a 
chap-name or pap-name, then the authentication packets sent by the 
local peer will have blank name values. This may cause 
authentication to fail for some PPP implementations.

set PPP module vccn port-authentication chap-name chap_name

Specifies the name the Cayman 3220-H sends in a CHAP response 
packet. The 

 argument is 1-32 alphanumeric characters. 

The information you enter must match the CHAP username 
configured in the remote PPP peer's authentication database.
