Figure 154 Example of the Supplicant Role
Note
The use of this port role should be strictly limited. Otherwise,
undesired switch operation may result. The port role should only be
used when the link will carry traffic from just one client or only
management traffic. Ports used to interconnect switches should
typically be set to the none role.
RADIUS
Accounting
The AT-S62 management software supports RADIUS accounting for
ports set to the Authenticator role. This feature allows the switch to send
information to the RADIUS server about the status of its supplicants. You
can view this information on the RADIUS server to monitor network
activity and use.
The switch sends accounting information to the RADIUS server
whenever one of the following events occur:
❑ Supplicant logs on
❑ Supplicant logs off
❑ A change in the status of an Authenticator port during an active
Supplicant session (for example, the port is reset or is changed
from the Authenticator role to None role while a Supplicant is
logged on)
