How to Logging In to NetEngine 8000 M by Using the Console Interface?

When setting up a local configuration environment with the console interface being used, you can log in to the NetEngine 8100 M, NetEngine 8000E M, NetEngine 8000 M Series by using the terminal emulation program on the PC.

Prerequisites

Figure 1 Networking diagram of logging in to the NetEngine 8100 M, NetEngine 8000E M, NetEngine 8000 M by using the console interface

• The NetEngine 8100 M, NetEngine 8000E M, NetEngine 8000 M is powered on and works properly.

• The PC is connected to the NetEngine 8100 M, NetEngine 8000E M, NetEngine 8000 M through asynchronous interfaces.

• Installing terminal emulation program on the PC (such as PuTTY.exe)

Perform the following configurations on the terminal emulation program on the PC.

The console port applies the non-standard serial port communication cable sequence. For more information, see ETH/OAM Management Cables in Hardware Description.

Procedure

1. Use a serial cable to connect the serial interface on the PC and the console interface on the NetEngine 8100 M, NetEngine 8000E M, NetEngine 8000 M.

   For details about the console interface, see the NetEngine 8100 M, NetEngine 8000E M, NetEngine 8000 M Hardware Description.

   

   If a third-party USB-to-RJ45 serial cable is used, it is recommended that the cable length be less than or equal to 2 m to ensure signal integrity.

2. Start the terminal emulation program such as PuTTY.exe on the PC.
3. On the PuTTY configuration page (shown in Figure 2), set the connection type to Serial.
   Figure 2 PuTTY configuration page
   

4. Select Serial under Connection from the left navigation tree on the PuTTY configuration page. On the page shown in Figure 3, set communication parameters of the port to be consistent with those on the device. (The following figure is for reference only. Use the default settings during configuration.)

5. Click Open. Then the system prompts you to set an authentication password, as shown in Figure 4. After the confirm the password, the system automatically saves it.

Commissioning Result

After the password is set, the command prompt (for example, <HUAWEI>) of the user view is displayed, which indicates that you have entered the user view and can perform configurations.

You can enter commands to configure the router or view its running status. Enter a question mark (?) when you need help.

• A password is entered in man-machine interaction mode. The system does not display the entered password.

• A password is a string of 8 to 16 case-sensitive characters and must contain at least two types of the following characters: uppercase letters, lowercase letters, digits, and special characters.

  Special characters do not include question marks (?) or spaces. However, when double quotation marks are used around a password, spaces are allowed in the password.

  • Double quotation marks cannot contain double quotation marks if spaces are used in a password.
  • Double quotation marks can contain double quotation marks if no space is used in a password.

  For example, the password "Aa123"45"" is valid, but the password "Aa 123"45"" is invalid.

The configured password is displayed in ciphertext in the configuration file.

If the login fails, click Disconnect and then Call. If the login still fails, repeat Step 1 to check whether the parameters or physical connections are correct. If they are correct, log in to the NetEngine 8100 M, NetEngine 8000E M, NetEngine 8000 M again.
