Advanced Application > AAA > TACACS+ Server Setup 

Authentication 
Server

Use this section to configure your TACACS+ authentication settings.

Mode

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. 

Select round-robin to alternate between the TACACS+ servers that it sends authentication 
requests to.

Timeout

Specify the amount of time in seconds that the Switch waits for an authentication request 
response from the TACACS+ server. 

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. 

Index

This is a read-only number representing a TACACS+ server entry.

IP Address

Enter the IP address of an external TACACS+ server in dotted decimal notation.
