Status Information
Status information is displayed at the bottom of the Configuration PPP
window. After you apply your changes, the PPP Link State will be “starting,”
indicating that the ProCurve Secure Router OS is trying to establish a PPP
connection with its peer. Ensure that the PPP Link State is eventually “up.”
For information about troubleshooting PPP, see “Troubleshooting the PPP
Interface” on page 6-59 of Chapter 6: Configuring the Data Link Layer
Protocol for E1, T1, and Serial Interfaces
PPP Authentication
The ProCurve Secure Router supports two authentication protocols for PPP:
Password Authentication Protocol (PAP) and Challenge Handshake Authen-
tication Protocol (CHAP).
When a ProCurve Secure Router asks a peer to authenticate itself using PAP,
the peer sends its password in clear text over the wire. The first router matches
the password to the password in its PPP database.
