switch attempts to use the primary server first, and
the secondary server second.

Displays the connection status between the server
and the switch – connected or not connected.

is secret and is not visible.

connection to the server. The default port is 49.
IP address
Displays the IP address for the primary and
secondary TACACS+ servers.
Timeout
Displays the period of time, in seconds, the switch
waits for a response from the TACACS+ daemon
before it times out and declares an error. The default
is 10 seconds.
Single
Displays if a single open connection is maintained
between the switch and TACACS+ daemon, or if the
switch opens and closes the TCP connection to the
TACACS+ daemon each time they communicate.
The default is false, which means the device does
not maintain the single open connection.

one, for all outgoing TACACS+ packets.
