Configuration Guide 802.1x Configuration
 The ports connected to the access layer switches must be set as controlled ports to control the accessed users, and
the users cannot access network resources unless they first pass the authentication.
Characteristics of this solution:
 The convergence layer device must be of high quality since the network is large and numerous users are connected,
since any of its fault may cause the failures of many users to normally access the network.
 User management is performed on the Radius Server in a centralized manner. The administrator does not have to
know which switch a user is connected to, making management much easier.
 The access layer device can be the less expensive non-NM switches (as long as they support transparent
transmission of EAPOL frames).
 The administrator cannot manage the device on the access layer through the network.
