• Usage Type—Enter the RADIUS server authentication type. The options are: 
- Login—RADIUS server is used for authenticating users that want to 
administer the switch.

Control.
- All—RADIUS server is used for authenticating user that wants to 
administer the switch and for authentication in 802.1X Access Control.
STEP  4 Click Apply. The RADIUS server is added, and the switch is updated.
Management Access Authentication
You can assign authentication methods to management access methods, such as 
SSH, console, Telnet, HTTP, and HTTPS. This authentication can be performed 
locally or on an external server, such as a TACACS+ or a RADIUS server. 
User authentication occurs in the order that the authentication methods are 
selected. If the first authentication method is not available, the next selected 
method is used. For example, if the selected authentication methods are RADIUS 
and Local, and all configured RADIUS servers are queried in priority order and do 
not reply, the user is authenticated locally.
If an authentication method fails or the user has insufficient privilege level, the user 
is denied access to the switch. In other words, if authentication fails at an 
authentication method, the switch stops; it does not continue and does not 
attempt to use the next authentication method. 
To define authentication methods for an access method:
STEP 1 Click Security > Management Access Authentication. The Management Access 
Authentication Page displays.
STEP  2 Select an access method from the Application list.
STEP  3 Use the arrows to move the authentication method between the Optional Methods 
column and the Selected Methods column. The first method selected is the first 
method that is used.
