Description

On interfaces with PPP encapsulation, configure PPP-specific interface properties.

For ATM2 IQ interfaces only, you can configure CHAP on the logical interface unit if the logical interface is configured with one of the following PPP over ATM encapsulation types:

  • atm-ppp-llc—PPP over AAL5 LLC encapsulation.

  • atm-ppp-vc-mux—PPP over AAL5 multiplex encapsulation.

Best Practice:

On inline service (si) interfaces for L2TP, only the chap and pap statements are typically used for subscriber management. We recommend that you leave the other statements subordinate to ppp-options—including those subordinate to chap and pap—at their default values.

The remaining statements are explained separately. Search for a statement in CLI Explorer or click a linked statement in the Syntax section for details.

Required Privilege Level

interface—To view this statement in the configuration.

interface-control—To add this statement to the configuration.

Release Information

Statement introduced before Junos OS Release 7.4.
