To specify a TACACS+ server host and configure its communication parameters, use the following
command in the CONFIGURATION mode:
To specify multiple TACACS+ server hosts, configure the
tacacs-server host command multiple times. If
multiple TACACS+ server hosts are configured, FTOS attempts to connect with them in the order in which
they were configured.
To view the TACACS+ configuration, use the
show running-config tacacs+ command in the EXEC
Privilege mode.
To delete a TACACS+ server host, use the
no tacacs-server host {hostname | ip-address} command.

Command Authorization
The AAA command authorization feature configures FTOS to send each configuration command to a
TACACS server for authorization before it is added to the running configuration.
By default, the AAA authorization commands configure the system to check both EXEC mode and
CONFIGURATION mode commands. Use the command
no aaa authorization config-commands to enable
only EXEC mode command checking.

port number. The default is 49.
• timeout seconds range: 0 to 1000. Default is 10
