Logging In to a Device Through the Console Port

Logging In to a Device Through the Console Port


After completing the console user interface configuration on a device, you can log in to the device through the console port. If the console user interface uses the default attribute settings and the default AAA authentication mode, the login process is as follows:


  1. Connect the DB9 female connector of the console cable to the serial port (COM) on the PC, and connect the RJ45 connector to the console port on the device, as shown in Figure 5-1.

    Figure 5-1  Connecting to the device through the console port

    If the device has two main processing units (MPUs), you can log in to the device through the console port on either of the two MPUs.

    If a maintenance terminal (PC) does not have a DB9 serial port, purchase a USB-to-DB9 cable that has a DB9 male connector with nuts. Connect the DB9 female connector of the console cable to the DB9 male connector of the USB-to-DB9 cable, and then connect the USB connector to the USB port of the maintenance terminal.

  2. Start the terminal emulation software on the PC. Create a connection, select the port for connection, and set communication parameters. (This section uses the third-party software SecureCRT as an example.)
    1. Click to establish a connection, as shown in Figure 5-2.

      Figure 5-2  Establishing a connection

    2. Set the port for connection and communication parameters, as shown in Figure 5-3.

      Select the port for connection. For example, you can view port information in Device Manager in the Windows operating system, and select the port for connection.

      Communication parameters of the terminal emulation software must be consistent with the default attribute settings of the console user interface on the device, which are 9600 bit/s baud rate, 8 data bits, 1 stop bit, no parity check, and no flow control.

      By default, no flow control mode is configured on the device. Because RTS/CTS is selected in the software by default, you need to deselect RTS/CTS; otherwise, you cannot enter commands.

  3. Click Connect. The following information will be displayed, prompting you to enter the user name and password. (In password authentication, the system prompts you to enter the password. The following output is only for reference.)

    Login authentication

    You can run commands to configure the device after login. Enter a question mark (?) whenever you need help.

Verifying the Configuration

  • Run the display users [ all ] command to check user login information on the user interface.
  • Run the display user-interface console 0 command to check user interface information.
  • Run the display local-user command to check the local user attributes.
  • Run the display access-user command to check information about online users.
