hostname

}

•

ip-address

—Name or IP address of the host.

•

hostname

—Hostname of the tacacs server. (Range: 1 - 158 characters)

•

single-connection

—Specify single-connection. Rather than have the device open and

close a TCP connection to the daemon each time it must communicate, the single-

connection option maintains a single open connection between the device and the

daemon.

•

port-number—

Specify a server port number. If unspecified, the port number defaults to

49. (Range: 0 - 65535)

•

timeout—

Specifies the timeout value in seconds. If no timeout value is specified, the

global value is used. (Range: 1 - 30)

•

key-string—

Specifies the authentication and encryption key for all TACACS

communications between the device and the TACACS server. This key must match the

encryption used on the TACACS daemon. If no key string value is specified, the global

value is used. (Range: 0 - 128 characters)

•

source—

Specifies the source IP address to use for the communication. If no source value

is specified, the global value is used.

•

priority—

Determines the order in which the servers will be used, when 0 is the highest

priority. If unspecified defaults to 0. (Range: 0 - 65535)

Default Configuration

No TACACS host is specified

Command Mode

Global Configuration mode

User Guidelines

• Multiple

tacacs-server host

commands can be used to specify multiple hosts.
