TACACS+ C
OMMANDS
TACACS+ provides access control for networked devices via one or more centralized servers. Similar to RADIUS, this
protocol simplifies authentication by making use of a single database that can be shared by many clients on a large network.
TACACS+ is based on the TACACS protocol (described in RFC1492) but additionally provides for separate authentication,
authorization, and accounting services. The original protocol was UDP based with messages passed in clear text over the
network; TACACS+ uses TCP to ensure reliable delivery and a shared key configured on the client and daemon server to
encrypt all messages.
tacacs-server host
Use the tacacs-server host command in Global Configuration mode to configure a TACACS+ server. This command
enters into the TACACS+ configuration mode. The <ip-address|hostname> parameter is the IP address or 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 the no tacacs-server host 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 the tacacs-server key 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 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.
Format
tacacs-server key [<key-string> | encrypted <key-string>]
Mode Global Config
no tacacs-server key
Use the no tacacs-server key command to disable 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 This key must match the key used on the TACACS+ daemon.
Format
no tacacs-server key <key-string>
Mode Global Config
