How Radius Authentication Works

BLADEOS 6.5.2 Application Guide

1.Remote administrator connects to the switch and provides user name and password.

2.Using Authentication/Authorization protocol, the switch sends request to authentication server.

3.Authentication server checks the request against the user ID database.

4.Using RADIUS protocol, the authentication server instructs the switch to grant or deny administrative access.

Configuring RADIUS on the Switch

Use the following procedure to configure Radius authentication on your switch.

1.Configure the IPv4 addresses of the Primary and Secondary RADIUS servers, and enable RADIUS authentication.

RS G8124(config)# radius-server primary-host 10.10.1.1

RS G8124(config)# radius-server secondary-host 10.10.1.2

RS G8124(config)# radius-server enable

2.Configure the RADIUS secret.

RS G8124(config)# radius-serverprimary-host 10.10.1.1 key <1-32 character secret>

RS G8124(config)# radius-serversecondary-host 10.10.1.2 key <1-32 character secret>

3.If desired, you may change the default UDP port number used to listen to RADIUS. The well-known port for RADIUS is 1812.

RS G8124(config)# radius-server port <UDP port number>

4.Configure the number retry attempts for contacting the RADIUS server, and the timeout period.

RS G8124(config)# radius-server retransmit 3

RS G8124(config)# radius-server timeout 5
