TACACS+ Remote Authentication
When conguring a TACACS+ server host, you can set dierent communication parameters, such as the key password.
Example of Specifying a TACACS+ Server Host

Dell(conf)#aaa authentication login tacacsmethod tacacs+
Dell(conf)#aaa authentication exec tacacsauthorization tacacs+
Dell(conf)#tacacs-server host 25.1.1.2 key Force

Specifying a TACACS+ Server Host
To specify a TACACS+ server host and congure its communication parameters, use the following command.
• Enter the host name or IP address of the TACACS+ server host.
CONFIGURATION mode
tacacs-server host {hostname | ip-address} [port port-number] [timeout seconds] [key key]
Congure the optional communication parameters for the specic host:
– port port-number: the range is from 0 to 65535. Enter a TCP port number. The default is 49.
– timeout seconds: the range is from 0 to 1000. Default is 10 seconds.
– key key: enter a string for the key. The key can be up to 42 characters long. This key must match a key congured on the
TACACS+ server host. This parameter must be the last parameter you congure.
If you do not congure these optional parameters, the default global values are applied.
Example of Connecting with a TACACS+ Server Host
To specify multiple TACACS+ server hosts, congure the tacacs-server host command multiple times. If you congure
multiple TACACS+ server hosts, Dell Networking OS attempts to connect with them in the order in which they were congured.
To view the TACACS+ conguration, use the show running-config tacacs+ command in EXEC Privilege mode.
To delete a TACACS+ server host, use the no tacacs-server host {hostname | ip-address} command.
