the access class from the server. A user, therefore, at least sees the login prompt. If the access class denies the connection, the system
closes the Telnet session immediately. The following example demonstrates how to configure the access-class from a server.
This configuration ignores the configured access-class on the VTY line. If you have configured a deny10 ACL on the server, the
system downloads it and applies it. If the user is found to be coming from the 10.0.0.0 subnet, the system also immediately closes the Telnet
connection. Note, that no matter where the user is coming from, they see the login prompt.
When configuring a server host, you can set different communication parameters, such as the key password.
Example of Specifying a Server Host
Dell(conf)#
Dell(conf)#aaa authentication login tacacsmethod
Dell(conf)#aaa authentication exec tacacsauthorization
Dell(conf)#tacacs-server host 25.1.1.2 key Force
Dell(conf)#
Dell(conf)#line vty 0 9
Dell(config-line-vty)#login authentication tacacsmethod
Dell(config-line-vty)#end
Specifying a Server Host
To specify a server host and configure its communication parameters, use the following command.
•
Enter the host name or IP address of the server host.
CONFIGURATION mode
tacacs-server host {
hostname
|
ip-address
} [port
port-number
] [timeout
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.
