data-call [authentication protocol | sent authentication protocol]
[chap | pap]
Use the data-call authentication protocol and data-call sent authentication protocol commands to set
the pre-authentication defaults for inbound demand routing calls. Use the no form of these commands to
return to the default settings. For more detailed information on CHAP and PAP, refer to the Technology
Review section of the command ppp authentication <protocol>
on page 200 .
Syntax Description
authentication protocol Sets the authentication protocol expected for inbound calls.
sent authentication protocol Sets the authentication protocol sent for inbound calls.
chap Configures CHAP authentication.
pap Configures PAP authentication.
Default Values
By default, there is no configuration for authentication.
Applicable Platforms
This command applies to the NetVanta 1000R, 3000, 4000, and 5000 Series units.
Command History
Release 11.1 Command was introduced.
Functional Notes
There are certain PPP parameters that must be known before PPP can negotiate an inbound call when
using demand routing. To ensure PPP convergence, it is recommended (in most cases) that demand
routing interfaces use the same settings as those specified in the data-call commands. If the PPP
parameters do not match the authenticated user, the link is renegotiated.
Usage Examples
The following example sets the authentication protocol expected for incoming calls to CHAP. The router
will then authenticate the peer using CHAP:
(config)#data-call authentication protocol chap
The following example sets the authentication protocol sent for incoming calls to PAP. This router may be
authenticated by the peer using PAP:
(config)#data-call sent authentication protocol pap
