Overview

Security is a term that covers several different aspects of network use and operation. One 
general type of security is control of the devices or users that can access the network. Ways of 
doing this include authenticating the user at the point of logging in. You can also control access 
by defining limits on certain types of traffic. Another general type of security operates to protect 
the operation of the switch itself. Security measures in this category include routing policies that 
can limit the visibility of parts of the network or denial of service protection that prevents the CPU 
from being overloaded. Finally, management functions for the switch can be protected from 
unauthorized use. This type of protection uses various types of user authentication.
