Figure 194. Example of the Authenticator Role

As mentioned earlier, the switch itself does not authenticate the user
names and passwords from the clients. That is the responsibility of the
authentication server, which contains the RADIUS server software.
Instead, a switch acts as an intermediary for the authentication server by
denying access to the network by the client until the client has provided
a valid username and password, which the authentication server
validates.

Supplicant Role

A switch port in the supplicant role acts as a client. The port assumes it
must log in by providing a valid user name and password to whatever
device it is connected to, typically another switch port.

Figure 195 illustrates the port role. Port 11 on switch B has been set to
the supplicant role. Now, whenever switch B is power cycled or reset and
initiates a link with switch A, it must log on by providing a username and
password. (You enter this information when you configure the port for
the supplicant role.)
