RADIUS Client
– 216 –
◆ RADIUS and TACACS+ logon authentication assigns a specific privilege level for
each user name and password pair. The user name, password, and privilege
level must be configured on the authentication server.
◆ You can specify three authentication methods in a single command to indicate
the authentication sequence. For example, if you enter “authentication login
radius tacacs local,” the user name and password on the RADIUS server is
verified first. If the RADIUS server is not available, then authentication is
attempted on the TACACS+ server. If the TACACS+ server is not available, the
local user name and password is checked.
Example
Console(config)#authentication login radius
Console(config)#

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.
