Description
This command configures an L2TP/IPsec VPN connection.
Syntax
Usage Guidelines
L2TP/IPsec relies on the PPP connection process to perform user authentication and protocol configuration. You
specify the protocol used for PPP authentication and whether SecureID tokens are cached on the controller.
Client addresses are assigned from a pool configured with the ip local pool command.

ppp
authentication
Enables the protocols for PPP authentication. This list should match
the L2TP configuration configured with the vpn-dialer command on
the controller.

to reauthenticate each time a network connection is lost.
——
CHAP
Use CHAP with PPP authentication.
EAP
Use EAP-TLS with PPP authentication. Specify this protocol for
Windows IPsec VPN clients that use Common Access Card (CAC)
Smart Cards that contain user information and digital certificates.
——
MSCHAP
Use MSCHAP with PPP authentication.
MSCHAPv2
Use MSCHAPv2 with PPP authentication. This is the default for L2TP
PAP
Use PAP with PPP authentication.
ppp securid

the time, in minutes, that the token is cached.
