Chapter 1 Configuration Mode of Common Commands for Routers

1.1 Service Description

1) The hierarchical protection mode has been adopted in the command line of the system. Command lines are classified into four levels, namely visit level, monitoring level, configuration level and management level. They are introduced as follows:

Visit level: Commands of this level involve command of network diagnosis tool (such as ping and tracert), command that starts from the local device and visits external device (including Telnet client side, SSH client side and RLOGIN) and so on. The operation of saving configuration file is not allowed on this level of commands.

Monitor level: Commands of this level, including the display command and the debugging command, are used to system maintenance, service fault diagnosis, etc. The operation of saving configuration file is not allowed on this level of commands.

Configuration level: Service configuration commands, including routing command and commands on each network layer are used to provide direct network service to the user.

Management level: They are commands that influence basis operation of the system and system support module, which plays a support role on service. Commands of this level involve file system command, FTP command, TFTP command, XModem downloading command, configuration file switching command, power supply control command, backup board control command, user management command, level setting command, system internal parameter setting command (non-protocol provision and non-RFC provision), etc.

2) Command mode

The system defines command line interfaces into command views. All commands of the system are registered with a command view (or command views). Commands under a view can only be executed from that view.

Presented below are functional characteristics of command views and the commands for entering the views.

1.2.2 Error Messages of the Command Line

I. All commands entered by a user are executed if they pass the syntax check; otherwise, error information is reported to the user.

Error messages Cause of the error

Unrecognized command

The command cannot be found.

The key word cannot be found.

Parameter type error

The parameter value exceeds the boundary.

Incomplete command Incomplete command inputted

Too many parameters Too many parameters inputted

Ambiguous command Indefinite parameters inputted

1.2.3 History Command

The command line interface provides the function similar to Doskey, which automatically saves the history commands input by the user. The user may access and repeatedly execute the history commands saved by this interface.By default, the interface line interface may save a maximum of 10 history commands for each user.

1.2.4 Display Characteristics

I. The command line interface provides the following displaying characteristics:

To facilitate users, the prompt and help information can be displayed in both Chinese and English.

When information can’t be displayed in one screen, the screen will pause, and the user can make 3 choices as shown in Table FC-2-1.

Chapter 2 Configuration through the Console Interface

2.1 Networking and Service Description

Figure 2-1

To set up the local configuration environment, just connect the serial port of the PC (or terminal) to the Console interface on the router’s active MPU through a special configuration cable.

2.2 Configuration Procedure

1) Open the HyperTerminal in the Windows2000 or Windows XP operating system of the PC. Set the communication parameters for the terminal as follows: Set the Baud Rate to 9600bit/s, Data Bit to 8, Stop Bit to 1, Parity Check to none and Flow Control to none; select VT100 or automatic detection as the terminal type, as shown in the following figure:

2) Power on the router. If a user does not want to enter the BOOTROM menu, he is asked to press the Enter key after completion of self-check, until the command line prompt <Quidway> appears.

Chapter 3 Remote Dial-in through the Aux Interface and a Modem

3.1 Networking and Service Description

Figure 3-1

3.2 Configuration Procedure

Connect the cables and Modems properly. The router is accompanied by a dark green AUX cable when it is shipped. The AUX cable has a RJ-45 connector at one end and a 9-pin or 25-pin serial port at the other end. It appears similarly to the Console cable, except that the serial port of the AUX cable has 9 or 25 pins, while the serial port of the Console cable has 9/25 holes. Plug the AUX cable’s RJ-45 connector in the AUX interface on the MPU, and connect the serial port to the Modem. Connect the telephone line properly. Up to now, you have laid the physical basis for remote dialing and login to the router through the AUX interface.

3.3 Configuration Reference

3.3.1 Configuring the Router’s AUX Interface

Configure a password for the Aux login user. In the user-interface view, configure the password for login to the system with the set password command.

[Quidway] User-interface aux 0

[Quidway-ui-aux0] authentication-mode password

[Quidway-ui-aux0] set authentication password simple Huawei [Quidway-ui-aux0] user privilege level 3

Configure the Modem to allow it to call in and call out.

3.3.2 Configuring the HyperTerminal

After the physical environment is set up and commands are configured, you may dial from the PC to log in to the system. The terminal application, for example, the HyperTerminal of Windows, is used for dialing login. The following figure illustrates the actual dialing:

Chapter 4 Configuration through Telnet

4.1 Networking and Service Description

Figure 4-1

4.2 Configuration Reference

I. Configure ip address of router

[Quidway]interface Ethernet 0/0

[Quidway-Ethernet0/0]ip address 1.1.1.1 255.0.0.0

After configured the ip address of the interface,configure the ip address of the PC(suggest ip

address of the PC is 1.1.1.2/8).

II. Configure a password for login in the Telnet mode

[Quidway] user-interface vty 0 4

[Quidway-ui-vty0-4] authentication-mode password

[Quidway-ui-vty0-4] set authentication password simple Huawei [Quidway-ui-vty0-4] user privilege level 3

III. Check connectivity between the PC and the router

Check the connectivity by pinging the router.

Chapter 5 Setting the Right to Access the Router

5.1 Configuration Reference

5.1.1 Configuring the Right

You may set the password at different levels using the command super password [ level user-level ] { simple | cipher } password.

[Quidway]super password level 1 cipher jack

[Quidway]super password level 2 cipher black

[Quidway]super password level 3 cipher brown

When you log in to the router through telnet, the system set the default access level to 0 for users.

When you log in to the router through telnet, you may use the command super [ level ] (the password varies with the level) to manage the right of access users.

[Quidway]super ?

INTEGER<0-3> Priority level

<cr>

You may manage the rights of access users by setting different levels for them.

[Quidway-ui-vty0-4]authentication-mode local

[Quidway]local-user test password cipher test

[Quidway]local-user test level 3

When you are trying to log in to the router through telnet, you will be asked to enter a username and a password.

5.1.2 Clear the Configuration

[Quidway]undo super password

[Quidway-ui-vty0-4]undo set authentication password

[Quidway]undo super password level 1
