Chapter 15: Setting RADIUS and TACACS+ Clients

Configuring the Authentication Server

Configuring a

TACACS+

Server

To configure an authentication server, choose from the following procedures:

“Configuring a TACACS+ Server” on page 168

“Configuring a RADIUS Server” on page 170

Note

Before you can configure an TACACS+ or RADIUS server, you must select an authentication method. See “Selecting the Authentication Method” on page 166.

To configure a TACACS+ server, do the following:

1.Select the Security tab.

The Security tab is displayed. See Figure 52 on page 158.

2.From the Security tab, select Authentication Servers.

The Authentication Server Configuration page is displayed. See Figure 55 on page 166.

3.Click the Tacacs+ tab.

The Authentication Server Configuration Page with the Tacacs+ tab is displayed. See Figure 55 on page 166.

Note

You cannot change the Timeout Value for a TACACS+ server. This field indicates the number of seconds, that the switch waits for a response from a TACACS+ server to an authentication request, before querying the next server in the list.

4.Specify the Key Value setting as needed.

This field defines the value of the global encryption key of the TACACS+ servers. You can define a global encryption key if you have one TACACS+ server or if there is more than one server and they all use the same encryption key. This value is used by the TACACS+ clients. The maximum length is 39 characters. Spaces and special characters are not permitted.The default value is “ATI.”
