seconds ] [key key ]
Configure the optional communication parameters for the specific 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 configured on the server host. This parameter must be the last parameter you
configure.
If you do not configure these optional parameters, the default global values are applied.
Example of Connecting with a Server Host
To specify multiple server hosts, configure the
tacacs-server host
command multiple
times. If you configure multiple server hosts, Dell Networking OS attempts to connect with
them in the order in which they were configured.
To view the configuration, use the
show running-config
command in EXEC
Privilege mode.
To delete a server host, use the
no tacacs-server host { hostname | ip-address }
command.

Command Authorization
The AAA command authorization feature configures Dell Networking OS to send each configuration
command to a TACACS server for authorization before it is added to the running configuration.
By default, the AAA authorization commands configure the system to check both EXEC mode and
CONFIGURATION mode commands. Use the
no aaa authorization config-commands
command
to enable only EXEC mode command checking.
If rejected by the AAA server, the command is not added to the running config, and a message displays:
04:07:48: %RPM0-P:CP %SEC-3-SEC_AUTHORIZATION_FAIL: Authorization failure
Command
authorization failed for user (denyall) on vty0 ( 10.11.9.209 )
