DESCRIPTION

Authentication

Use this section to configure your RADIUS authentication settings.

Server

 

 

 

Mode

This field only applies if you configure multiple RADIUS servers.

 

Select index-priorityand the Switch tries to authenticate with the first configured RADIUS

 

server, if the RADIUS server does not respond then the Switch tries to authenticate with the

 

second RADIUS server.

 

Select round-robinto alternate between the RADIUS servers that it sends authentication

 

requests to.

 

 

Timeout

Specify the amount of time in seconds that the Switch waits for an authentication request

 

response from the RADIUS server.

 

If you are using index-priorityfor your authentication and you are using two RADIUS

 

servers then the timeout value is divided between the two RADIUS servers. For example, if

 

you set the timeout value to 30 seconds, then the Switch waits for a response from the first

 

RADIUS server for 15 seconds and then tries the second RADIUS server.

 

 

Index

This is a read-only number representing a RADIUS server entry.

 

 

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. You need not change this

 

value unless your network administrator instructs you to do so.
