Configuring the HWTACACS server
Introduction
This document provides login configuration examples. It also provides examples for implementing user access control by using command authorization and command accounting.
Prerequisites
The configuration examples in this document were created and verified in a lab environment, and all the devices were started with the factory default configuration. When you are working on a live network, make sure you understand the potential impact of every command on your network.
This document assumes that you have basic knowledge of login management.
Example: Configuring console login
Network configuration
Configure console login so users must pass local authentication to log in to the device through the console port.
Analysis
The port properties for the terminal emulation program must match the console port's default settings.
By default, a local user is assigned the default user role network-operator and is not assigned any service type. To enable the user to log in through the console port, you must assign the terminal service type to the user. To enable the user to manage the device, you must assign the network-admin user role to the user.
Restrictions and guidelines
When you configure console login, follow these restrictions and guidelines:
· Identify the console port carefully to make sure you are connecting to the correct port.
· Prepare a console terminal, for example, a PC. Make sure the console terminal has a terminal emulation program, such as HyperTerminal or PuTTY. For information about how to use terminal emulation programs, see the programs' user guides.
· The required terminal emulation program varies by operating system.
¡ On the Windows Server 2003 or Windows XP operating system, use HyperTerminal.
¡ On the Windows Server 2008, Windows Vista, Windows 7, and other operating systems, use a third-party terminal emulation program. For information about how to use the third-party terminal emulation program, see the user guide or online help for the program.
Procedures
1. Turn off the PC if the PC is on.
2. Connect the DB-9 female connector of the console cable to the serial port of the PC.
3. Identify the console port of the device carefully and connect the RJ-45 connector of the console cable to the console port.
IMPORTANT: The serial ports on PCs do not support hot swapping. To connect a PC to an operating device, first connect the PC end. To disconnect a PC from an operating device, first disconnect the device end. |
Figure 1 Connecting a configuration terminal to the console port
4. Turn on the PC.
5. On the PC, launch the terminal emulation program and create a connection to the device. Set the port properties so the port properties match the following console port default settings:
¡ Bits per second—9600 bps.
¡ Flow control—None.
¡ Parity—None.
¡ Stop bits—1.
¡ Data bits—8.
6. Power on the device and press Enter as prompted.
The user view prompt appears. To get help, enter a question mark (?).
Line con1 is available.
Press ENTER to get started.

Example: Configuring Telnet login
Network configuration
As shown in Figure 2, users need to log in to the device remotely to manage the device.
· Configure Telnet login to enable users to Telnet to the device.
· Configure Telnet user authentication so a Telnet user must provide the correct username and password at login.
· Configure access control so only Telnet users at 192.168.0.46/24 and 192.168.0.52/24 can Telnet to the device.
· Configure two local users.
¡ One local user can manage the device.
¡ One local user can use only the read commands of features.
Analysis
Telnet service is disabled by default. To enable Telnet login, you must enable Telnet service.
To control Telnet login, configure an ACL to permit access only from the specified IP addresses.
By default, a local user is assigned the default user role network-operator. To restrict a local user to read commands, you must create a user role that can access only read commands.

Example: Configuring login user command authorization and accounting
Network configuration
As shown in Figure 3, Host A needs to log in to the device to manage the device.
For device security purposes, configure the device to perform the following tasks:
· Allow Host A to Telnet in after authentication.
· Use the HWTACACS server to control the commands that the user can execute.
· Send commands executed by users to the HWTACACS server to monitor and control user operations on the device.
Analysis
To implement command authorization and accounting, you must perform the following tasks:
· Enable scheme authentication and configure a HWTACACS scheme on the device.
· Configure an account on the HWTACACS server for the Telnet user and assign commands for the user to use.
Restrictions and guidelines
The command authorization function takes effect immediately after you execute the command authorization command. Before executing this command, you must complete the following tasks:
· Configure a user account on the HWTACACS server and specify the commands for the user to use.
· Configure the required HWTACACS scheme on the device.
