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.
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.
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.
