DESCRIPTION

State

Select Enable to permit 802.1x authentication on the Switch.

 

Note: You must first enable 802.1x authentication on the Switch

 

before configuring it on each port.

 

 

Authentication

Select whether to use Local or RADIUS as the authentication method.

Method

The Local method of authentication uses the “guest” and “user” user

 

 

groups of the user account database on the Switch itself to authenticate.

 

However, only a certain number of accounts can exist at one time.

 

RADIUS is a security protocol used to authenticate users by means of

 

an external server instead of an internal device user database that is

 

limited to the memory capacity of the device. In essence, RADIUS allows

 

you to validate an unlimited number of users from a central location.

 

 

Primary Radius

When RADIUS is selected as the 802.1x authentication method, the

Server

Primary Radius Server will be used for all authentication attempts.

 

 

IP Address

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

 

notation.

 

 

UDP Port

The default port of a RADIUS server for authentication is 1812.

 

 

Shared Key

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.

 

 

Second Radius

This is the backup server used only when the Primary Radius Server is

Server

down.
