Customizing Caller Resolution

For security purposes, all three dial services use a PPP identification mechanism

to determine who is calling the router. PPP performs this identification process

using one of two authentication protocols, CHAP or PAP.

CHAP is the default authentication protocol. To configure PAP, you must edit the

PPP interface configuration and modify the Site Manager parameter Local

Authentication Protocol parameter before setting up the caller resolution table.

For instructions on how to set this parameter, see Configuring PPP Services.

There is no equivalent BCC parameter.

To identify remote callers, you enter the caller name and CHAP secret or PAP

password of each remote caller in the caller resolution table, and assign a local

demand, primary, or bandwidth circuit to each caller.

The authentication process starts during link negotiation. The remote caller

includes its CHAP name or PAP ID in the CHAP challenge or PAP authenticate

request to the called router. When the called router receives the call, it checks its

caller resolution table for a matching entry. If the remote caller is authorized, the

called router activates the assigned circuit.

For more information about authentication, see Chapter 5, “Implementation Notes

for All Dial Services.”

This chapter explains how to modify your caller resolution information using the

BCC (dial backup only) and Site Manager.

Note:

When you configure a PPP connection using Site Manager, it creates a

generic PPP line record that all pools use for identification.
