4.2.9. Configuring the PPP Security Settings
The PPP protocol adds security to the communication, and therefore,
additional parameters need to be configured in the system. This screen is
not relevant for a SLIP connection.
To configure the PPP Security settings, perform the following operations:
1. Connect to the Terminal.
2. From the Main Configuration menu, select Full Configuration.
5. From the Full Configuration menu, select (3) Serial Configuration.
3. From the Serial Configuration menu, select (2) PPP Security. The PPP
Security menu appears.

4. Select (1) PPP Authentication Protocol. Define the protocol:
— 0 = None
— 1 = PAP (without encryption)
— 2 = CHAP (with encryption)
5. Select (2) PPP Authentication Mode.
— 2 = GUEST: The IDU gives the “user name” and the “password” to
the network manager.
— 3 = HOST: The IDU receives the “use name” and the “password”
from the network manager and validates them.
— 4 = DYNAMIC: When the IDU receives a phone call, then it acts as
HOST. If it initiates a call to the network manager (SNMP trap), it
will act like a GUEST. In case of a direct connection (without a
dialup modem), it acts as HOST.
