To monitor the configuration, issue the show interfaces interface-name command.

Configured options are displayed in the PPP parameters field for the physical interface.

Configuring PPP CHAP Authentication

For interfaces with PPP encapsulation, you can configure interfaces to support the PPP

Challenge Handshake Authentication Protocol (CHAP), as defined in RFC 1994,

PPP Challenge Handshake Authentication Protocol (CHAP). When you enable CHAP on

an interface, the interface can authenticate its peer and can be authenticated by its peer.

For information about configuring CHAP, see “Configuring the PPP Challenge Handshake

Authentication Protocol” on page 493.

Configuring the PPP Clear Loop Detected Timer

When a Point-to-Point Protocol (PPP) session detects a loop, the loop detected flag is

set. If the flag is not cleared by the protocol after the loopback is cleared, the clear loop

detected timer clears the flag after the specified time has elapsed.

To configure the clear loop detected timer for the LCP component of a PPP session,

include the loopback-clear-timer statement, and specify the number of seconds.

loopback-clear-timer seconds;

You can include this statement at the following hierarchy levels:

•

[edit interfaces interface-name unit logical-unit-number ppp-options]

•

[edit logical-systems logical-system-name interfaces interface-name unit

logical-unit-number ppp-options]

To monitor the configuration, issue the show interfaces interface-name extensive command.
