Hierarchy Level


Configure the Password Authentication Protocol (PAP). Use PAP authentication as a means to provide a simple method for the peer to establish its identity using a two-way handshake. This is done only upon initial link establishment.

After the link is established, an ID and password pair is repeatedly sent by the peer to the authenticator until authentication is acknowledged or the connection is terminated.

Best Practice:

On inline service (si) interfaces for L2TP, only the pap statement itself is typically used for subscriber management. We recommend that you leave the subordinate statements at their default values.

The remaining statements are explained separately. Search for a statement in CLI Explorer or click a linked statement in the Syntax section for details.
