Chapter 1 BayStack 420 Switch 35

Security

The BayStack 420 Switch security features provide two levels of security for your local area network (LAN):

RADIUS-based security—limits administrative access to the switch through user authentication

MAC address-based security—limits access to the switch based on allowed source MAC addresses

Figure 5 shows a typical campus configuration using the BayStack 420 Switch security features. This example assumes that the switch, the teachers’ offices and classrooms, and the library are physically secured. The student dormitory may (or may not be) physically secure.
