that contain settings for using AAA servers. 

 

3-6.1 Configuration

 

    

This  section  describes  how  to  configure  AAA  setting  of    or 
RADIUS server.  

 

Web Interface  

To configure a Common Configuration of AAA in the web interface: 

 

1.   Set Timeout (Default is 15 seconds). 
2.   Set Dead Time (Default is 300 seconds). 

 

To configure a  Authorization and Accounting Configuration of 
AAA in the web interface:

web interface: 

 

1.  Check 

―Enabled‖. 

2.  Specify IP address or Hostname for Radius Server. 
3.   Specify Authentication Port for Radius Server (Default is 1812). 
4.  Specify the Secret with Radius Server. 

 

To configure a RADIUS Accounting Server Configuration of AAA in the web 
interface:
