ADTRAN 1000R Series data-call [authentication protocol | sent authentication protocol] [chap

Command Reference Guide Global Configuration Mode Command Set

data-call [authentication protocol | sent authentication protocol]

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.

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 p arameters 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 au thentication protocol pap
