DESCRIPTION
This field is only valid if you configure multiple TACACS+ servers.
Select index-priority and the device tries to authenticate with the first configured
TACACS+ server, if the TACACS+ server does not respond then the device tries to
authenticate with the second TACACS+ server.
Select round-robin to alternate between the TACACS+ servers that it sends
authentication requests to.
Specify the amount of time in seconds that the device 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 device waits for a response from the
first TACACS+ server for 15 seconds and then tries the second TACACS+ server.
The first column displays a read-only number representing a TACACS+ server entry.
Enter the IP address of an external TACACS+ server in dotted decimal notation.
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.
Specify a password (up to 32 alphanumeric characters) as the key to be shared between
the external TACACS+ server and the device. This key is not sent over the network. This
key must be the same on the external TACACS+ server and the device.
