6. Enter the System Secret. This is the Concentrator’s own CHAP secret, used in authentication negotiation
not only with CSM but also whenever the Concentrator calls out to remote devices that use CHAP.
7. Enter the System Password. This is the Concentrator’s PAP secret, used for authentication negotiation
when the Concentrator calls out to a remote device that uses PAP.
8. Prioritize the PPP Authentication Protocols to be used for authenticating remote devices. By default, the
Concentrator will authenticate remote devices using CHAP first and PAP second (as shown in the example
screen). You may change the defaults to meet your network’s requirements. For example, if the
Concentrator’s remote devices only use PAP, you will need to change the priority to PAP first, and either
CHAP or NONE second. Choices for the preferred authentication protocol are CHAP or PAP. Choices
for the second protocol are CHAP, PAP, or NONE. Use the space bar to toggle the selection.
9. Select SAVE and then RETURN to return to the Module Configuration menu.
