1762 CHAPTER 104: L2TP CONFIGURATION COMMANDS

By default, no L2TP group exists.

When you use the undo l2tp-groupcommand to remove an L2TP group, all configuration information associated with the group will be deleted.

Related command: allow l2tp and start l2tp.

Example # Create an L2TP group numbered 2 and enter its view.

<Sysname> system-view [Sysname] l2tp-group 2 [Sysname-l2tp2]

mandatory-chap

Syntax	mandatory-chap
	undo mandatory-chap
View	L2TP group view
Parameter	None
Description	Use the mandatory-chapcommand to force the LNS to perform a CHAP
	authentication of the user.
	Use the undo mandatory-chapcommand to disable CHAP authentication on
	the LNS.
	By default, an LNS does not perform CHAP authentication of users.
	An LNS authenticates the client in addition to the proxy authentication that occurs
	at the LAC for higher security. If the mandatory-chapcommand is used, two
	authentications are performed for the clients connected to the VPN through an
	initialized tunnel of the NAS: one on the NAS side and the other on the LNS side.
	Some PPP clients may not support the second authentication. In this case, the local
	CHAP authentication will fail.
Related command:	mandatory-lcp.
Example	# Perform CHAP authentication by force.
	<Sysname> system-view
	[Sysname] l2tp-group 1
	[Sysname-l2tp1] mandatory-chap
