User Guidelines
To specify multiple hosts, multiple tacacs-server host commands can be used.
TACACS servers are keyed by the host name, therefore it is advisable to use
unique host names.
Example
The following example specifies a TACACS+ host.
console(config)#tacacs-server host 172.16.1.1
console(config-tacacs)#
tacacs-server key
Use the tacacs-server key command in Global Configuration mode to set the
authentication and encryption key for all TACACS+ communications
between the switch and the TACACS+ daemon. To disable the key, use the
no form of this command.
