Command History
Usage Guidelines You need to configure the TACACS+ preshared key to authenticate the switch to the TACACS+ server.
The length of the key is restricted to 65 characters and can include any printable ASCII characters (white
spaces are not allowed). You can configure a global key to be used for all TACACS+ server
configurations on the switch. You can override this global key assignment by explicitly using the key
option in the tacacs-server host command.
This command is only available when the TACACS+ feature is enabled using the tacacs+ enable
command.
Examples The following example configures TACACS+ server shared keys.
switch# config terminal
switch(config)# tacacs-server key AnyWord
switch(config)# tacacs-server key 0 AnyWord
switch(config)# tacacs-server key 7 public
key Global TACACS+ shared secret.
0 Configures a preshared key specified in clear text (indicated by 0) to

is the default.
7 Configures a preshared key specified in encrypted text (indicated by 7) to
