Chapter 15: Setting RADIUS and TACACS+ Clients

6.Change the following settings as needed:

IP Address— Specifies the IP address of a RADIUS server on the network. The IP address must be in the following IPv4 format: xxx.xxx.xxx.xxx.

Order— Select an index number for the IP address which indicates the priority of the RADIUS server. The switch queries the servers in the order in which they are listed in its table, starting with 1. The range is 1 to 3.

Accounting Port— Select the accounting port for the RADIUS server. This is the UDP destination port for RADIUS accounting requests. If you select 0, the server is not used for accounting. By default, the UDP port for accounting is 1813.

Authentication Port— Specifies the UDP destination port for RADIUS authentication requests. If you select 0, the server is not used for authentication. The default UDP port for authentication is 1812.

Key— Specifies the encryption key used by this RADIUS server. This value is needed when you configure a RADIUS client. The maximum length is 39 characters. Spaces and special characters are not permitted.
