the authentication server needs to be configured on the switch. RADIUS. In practical applications,

you can use an authentication server, you can also use two authentication servers, one as the main

authentication server, one as backup authentication server. If the switch is configured with two

authentication server IP addresses, when the switch and the main authentication server interrupt

communication, you can switch to the backup authentication server communication。

The following command configures the IP address of the master authentication server in the

global CONFIG mode：

Switch(config)#radius-server host <ip-address>

The following command configures the IP address of the backup authentication server in the

global CONFIG mode：

Switch(config)#radius-server option-host <ip-address>
