Configuring RADIUS authentication
The RADIUS protocol provides a way to authenticate users by using a
dedicated network resource. This network resource contains a list of eligible
user names and passwords and their associated access rights. When you
use RADIUS to authenticate access to a switch, the user supplies a user
name and password and this information is checked against the existing list.
If the user credentials are valid, the user can access the switch.
If you selected RADIUS Authentication for any of the switch authentication
options in the previous three sections, you must specify the RADIUS
server settings to complete the process. To set the RADIUS Authentication
parameters, select Administration > Security > RADIUS and perform the
following procedure.
