Usage Guidelines
The single-connection command allows the TACACS+ server to handle a greater number of TACACS
operations than would be possible if multiple TCP connections were used to send requests to a server.
The TACACS+ server that is being used must support single-connection mode for this to be effective; otherwise,
the connection between the network access server and the TACACS+ server locks up or you can receive
unauthentic errors.

Examples
The following example shows how to configure a single TCP connection to be made with the TACACS+
server (IP address 209.165.200.226) and all authentication, authorization, accounting requests to use this TCP
connection. This works only if the TACACS+ server is also configured in single-connection mode. To configure
the TACACS+ server in single connection mode, refer to the respective server manual.
