Configuring Network Security AAA Configuration
Tips: 
The logged-in guests can enter the Enable password on this page to get 
administrative privileges.
On the Server
The accounts created by the RADIUS/TACACS+ server can only view the configurations 
and some network information without the Enable password.
Some configuration principles on the server are as follows:
For Login authentication configuration, more than one login account can be created on 
the server. Besides, both the user name and password can be customized.
For Enable password configuration:
On RADIUS server, the user name should be set as $enable$, and the Enable password 
is customizable. All the users trying to get administrative privileges share this Enable 
password.
On TACACS+ server, configure the value of “enable 15“ as the Enable password in the 
configuration file. All the users trying to get administrative privileges share this Enable 
password.
