Networking Requirements

As shown in Figure 6-8, the PC and device are reachable to each other. Users require that the device be remotely configured and managed in an easy way. To meet the requirement, configure AAA authentication for Telnet users on the server.

Configuration Roadmap

The configuration roadmap is as follows:

  1. Log in to the device using Telnet to remotely maintain the device.
  2. Configure the administrator user name and password, and configure an AAA authentication policy to ensure that only users passing the authentication can log in to the device.

Procedure

  1. Enable the server function.

    <HUAWEI> system-view
[HUAWEI] sysname Telnet_Server
[Telnet_Server] telnet server enable

  2. Set parameters for the VTY user interface.

    # Set the maximum number of VTY user interfaces.

    [Telnet_Server] user-interface maximum-vty 15

    # Set terminal attributes for the VTY user interface.

    [Telnet_Server] user-interface vty 0 14
[Telnet_Server-ui-vty0-14] protocol inbound telnet
[Telnet_Server-ui-vty0-14] shell
[Telnet_Server-ui-vty0-14] idle-timeout 20
[Telnet_Server-ui-vty0-14] screen-length 0
[Telnet_Server-ui-vty0-14] history-command max-size 20

    # Set an authentication mode for the VTY user interface.

    [Telnet_Server-ui-vty0-14] authentication-mode aaa
[Telnet_Server-ui-vty0-14] quit

  3. Configure the login user information.

    # Set an authentication mode for login users.

    [Telnet_Server] aaa
[Telnet_Server-aaa] local-user admin1234 password irreversible-cipher Helloworld@6789
[Telnet_Server-aaa] local-user admin1234 service-type telnet
[Telnet_Server-aaa] local-user admin1234 privilege level 3
[Telnet_Server-aaa] quit

  4. Log in to the client.

    Run commands on the Windows Command Prompt of the PC to log in to the device using Telnet.

    C:\Documents and Settings\Administrator> telnet 10.137.217.177 23

    Press Enter, and enter the configured user name and password in the login window. If authentication succeeds, the CLI is displayed, indicating that you have successfully logged in to the device. (The following information is only for reference.)

    Login authentication


Username:admin1234
Password:
Info: The max number of VTY users is 15, and the number
      of current VTY users on line is 2.
      The current login time is 2012-08-06 18:33:18+00:00.
