9.13.2 Authentication Settings 
Authentication Settings is designed to specify local or remote authentication mechanism. 
Local authentication manages access authority by using the user name and password set on 
switch manually. Remote Authentication manages access authority by using Remote Access 
Authentication Server based on RADIUS protocol. 
  If using remote authentication server, the user must set the related parameters for the 
authentication methods of RADIUS and group, if there are multiple RADIUS servers, 
the authentication order depends on the time of configuring server. It will go to the 
next authentication server only when the current authentication server fails. 
  Users can choose from four methods of authentication: none, local, RADIUS and 
group. 
The order depends on the time of configuring command. It will go to the next authentication 
method only when the current authentication fails.
