Chapter 1 BayStack 420 Switch

209418-A

In this configuration example, the following security measures are implemented:

•

The switch

— RADIUS-based security is used to limit administrative access to the 

switch through user authentication (see 

— MAC address-based security is used to allow up to 448 authorized 

stations (MAC addresses) access to one or more switch ports
(see 

).

— The switch is located in a locked closet, accessible only by authorized 

Technical Services personnel.

•

Student dormitory

Dormitory rooms are typically occupied by two students and have been 
prewired with two RJ-45 jacks. Only students who are authorized (as 
specified by the MAC address-based security feature) can access the switch 
on the secured ports.

•

Teachers’ offices and classrooms

The PCs that are located in the teachers’ offices and in the classrooms are 
assigned MAC address-based security that is specific for each classroom and 
office location. The security feature logically locks each wall jack to the 
specified station and prevents unauthorized access to the switch should 
someone attempt to connect a personal laptop PC into the wall jack. The 
printer is assigned as a single station and is allowed full bandwidth on that 
switch port.

It is assumed that all PCs are password protected and that the classrooms and 
offices are physically secured.

•

Library

The wall jacks in the library are set up so that the PCs can be connected to any 
wall jack in the room. This arrangement allows the PCs to be moved 
anywhere in the room. The exception is the printer, which is assigned as a 
single station with full bandwidth to that port.

It is assumed that all PCs are password protected and that access to the library 
is physically secured.
