hostname of the TACACS+ server. To specify multiple hosts, multiple tacacs-server host commands can
be used.
Format tacacs-server host ip-address|hostname
Mode Global Config
no tacacs-server host
Use this command to delete the specified hostname or IP address. The ip-address|hostname
parameter is the IP address of the TACACS+ server.
Format no tacacs-server host ip-address|hostname
Mode Global Config
tacacs-server key
Use this command to set the authentication and encryption key for all TACACS+ communications
between the switch and the TACACS+ daemon. The key-string parameter has a range of 0 - 128
characters and specifies the authentication and encryption key for all TACACS communications
between the switch and the TACACS+ server. This key must match the key used on the TACACS+
daemon.
Text-based configuration supports the TACACS server’s secrets in encrypted and non-encrypted
format. When you save the configuration, these secret keys are stored in encrypted format only. If you
want to enter the key in encrypted format, enter the key along with the encrypted keyword. In the show
running-config command’s display, these secret keys are displayed in encrypted format. You cannot
show these keys in plain text format.
The ! (exclamation point) character cannot be used as the first character in a TACACS+ server password,
unless the password is entered inside quotation marks from the CLI. We recommend using quotation
marks whenever you create passwords and keys that contain the ! character – for example, #tacacs-
server key <"!234567">.
