•PAP—For all connection types.
•CHAP—For L2TP-over-IPSec.
•MS-CHAPv1—For L2TP-over-IPSec.
•MS-CHAPv2—For L2TP-over-IPSec, and for regular IPSec remote access connections when the

Attribute Support

The security appliance supports the following sets of RADIUS attributes:
•Authentication attributes defined in RFC 2138.
•Accounting attributes defined in RFC 2139.
•RADIUS attributes for tunneled protocol support, defined in RFC 2868.
•Cisco IOS VSAs, identified by RADIUS vendor ID 9.

RADIUS Authorization Functions

Thesecurity appliance can use RADIUS servers for user authorization for network access using dynamic
access lists or access list names per user. To implement dynamic access lists, you must configure the
RADIUS server to support it. When the user authenticates, the RADIUS server sends a downloadable
access list or access list name to the security appliance. Access to a givenservice is either permitted or
denied by the access list. The security appliance deletes the access list when the authentication session
expires.
