EAPOL-based security
BPS 2000 software version 1.1 provides support for security based on the
Extensible Authentication Protocol over LAN (EAPOL), which uses the EAP as

control on internal LANs.
Refer to “Security” on page 75 for complete information on EAPOL-based
security. For information on configuring EAPOL-based security using the
Console Interface (CI) menus, refer to Chapter 3. To configure this feature using
the Web-based management system, refer to
Using Web-based Management for
the Business Policy Switch 2000 Software Version 2.0 . To use Device Manager
