Chapter 25 AAA 25.2.2 TACACS+ Server Setup Use this screen to configure your TACACS+ server settings. See Section 25.1.2 on page 202 for more information on TACACS+ servers. Click on the TACACS+ Server Setup link in the Authentication and Accounting screen to view the screen as shown. Figure 108 Advanced Application > AAA > TACACS+ Server Setup The following table describes the labels in this screen. Table 68 Advanced Application > AAA > TACACS+ Server Setup LABEL Authentication Server Mode DESCRIPTION Use this section to configure your TACACS+ authentication settings. This field is only valid if you configure multiple TACACS+ servers. Select index-priority and the Switch tries to authenticate with the first configured TACACS+ server, if the TACACS+ server does not respond then the Switch tries to authenticate with the second TACACS+ server. Timeout Select round-robin to alternate between the TACACS+ servers that it sends authentication requests to. Specify the amount of time in seconds that the Switch waits for an authentication request response from the TACACS+ server. Index IP Address If you are using index-priority for your authentication and you are using two TACACS+ servers then the timeout value is divided between the two TACACS+ servers. For example, if you set the timeout value to 30 seconds, then the Switch waits for a response from the first TACACS+ server for 15 seconds and then tries the second TACACS+ server. This is a read-only number representing a TACACS+ server entry. Enter the IP address of an external TACACS+ server in dotted decimal notation. MES3500-24/24F User's Guide 205
