RADIUS Client

Remote Authentication Dial-in User Service (RADIUS) is a logon authentication
protocol that uses software running on a central server to control access to
RADIUS-aware devices on the network. An authentication server contains a
database of multiple user name/password pairs with associated privilege levels for
each user or group that require management access to a switch.
