Managing Security

The Authentication List screen contains information for defining an authentication method for the 
selected Authentication List. For example, if the user selects TACACS+ as the first entry, None as 
the second, this causes authentication to first occur at the TACACS+ server. If the TACACS+ 
server is inaccessible or not defined, the session is permitted.

Once the Authentication List is defined as Local, it is not possible to define an alternative 
authentication method as it is a built-in system authentication method.

In order to configure RADIUS/TACACS+ authentication, the user name should be configured as 
$enab15$ on the RADIUS/TACACS+ server.

To configure the Authentication List method:

1. Click Security > Management Security > Authentication List. The Authentication List 

screen displays:

The Authentication List screen contains the following fields: 

•

Local – Authenticate the user at the device level. The device checks the user name and 
password for authentication

–
