PPP Configuration Commands
This section lists the subset of PPP configuration commands that apply when an ATM sub‐
interface is configured for PPPoA or PPPoE encapsulation.

interface specifying encapsulation type PPPoA or PPPoE.
Syntax
ppp chap {hostname <name> | password pwd | refuse}
Syntax of the “no” Form
The no form of this command returns this parameter to its default setting:
