Configuring PAP on Dialer Interfaces (Optional)

You can configure dialer interfaces to support the Password Authentication Protocol (PAP). PAP allows a simple method for a peer to establish its identity using a two-way handshake during 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.

For more information about PAP, see the JUNOS Network Interfaces Configuration Guide.

To configure PAP on the dialer interface, create an access profile and then configure the dialer interface:

  1. Navigate to the top of the configuration hierarchy in either the J-Web or CLI configuration editor.
  2. Perform the configuration tasks described in Table 85.
  3. If you are finished configuring the router, commit the configuration.

  2. In the interface name box, click dl0.
  3. In the Interface unit number box, click 0.

From the [edit] hierarchy level, enter
