Authentication
Server
Use this section to configure your TACACS+ authentication settings.
Mode This field is only valid if you configure multiple TACACS+ servers.
Select inde x- prio rity 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- ro bin 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 inde x- p rio rity 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.
TCP Port The default port of a TACACS+ server for authentication is 49. You need not change this value
unless your network administrator instructs you to do so.
Shared Secret Specify a password (up to 32 alphanumeric characters except [ ? ], [ | ], [ ' ], [ " ] or [ , ]) as the
key to be shared between the external TACACS+ server and the Switch. This key is not sent over
the network. This key must be the same on the external TACACS+ server and the Switch.
Delete Check this box if you want to remove an existing TACACS+ server entry from the Switch. This
entry is deleted when you click Apply.
