Chapter 1 BayStack 420 Switch 35
Using the BayStack 420 10/100/1000 Switch
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.
