13.6 RADIUS

RADIUS (Remote Authentication Dial-In User Service) authentication is a popular protocol used to authenticate users by means of an external server instead of (or in addition to) an internal device user database that is limited to the memory capacity of the device. In essence, RADIUS authentication allows you to validate an unlimited number of users from a central location.

DESCRIPTION

Authentication Server

 

 

 

IP Address

Enter the IP address of the external RADIUS server in dotted decimal

 

notation.

 

 

UDP Port

The default port of the RADIUS server for authentication is 1812. You

 

need not change this value unless your network administrator instructs you

 

to do so.

 

 

Shared Secret

Specify a password (up to 32 alphanumeric characters) as the key to be

 

shared between the external RADIUS server and the switch. This key is

 

not sent over the network. This key must be the same on the external

 

RADIUS server and the switch.

 

 

Apply

Click Apply to save your changes.

 

 

13.7 Boot Config

You can store up to two configuration files on the switch. Only one configuration file is used at a time. By default the switch uses the first configuration file (with an index number of 1). You can set the switch to use another configuration file.

Use the Boot Config screen to select which configuration file you want the switch to use after the next system reboot.

1Right-click on a switch and click Configuration > System Configuration and the Boot Config tab.
