Usage Guidelines

This command first appeared in Cisco IOS Release 11.2.

This command allows you to replace several username and password configuration commands with a single copy of this command on any dialer interface or asynchronous group interface.

This command is used for remote CHAP authentication only (when authenticating to the peer) and does not affect local CHAP authentication.

Example

The following example configures interface BRI 0 for PPP encapsulation. If a CHAP challenge is received from a peer whose name is not found in the global list of usernames, the encrypted secret 7 1234567891 is decrypted and used to create a CHAP response value.

	interface bri0
	encapsulation ppp
	ppp chap password 7 1234567891
