(Optional) Configuring Attributes for the Console User Interface

(Optional) Configuring Attributes for the Console User Interface


The data transmission and screen display attributes of the console user interface are as follows:
  • Data transmission attributes: transmission rate, flow control mode, parity bit, stop bit, and data bit. These attributes determine the data transmission mode used in the console port login process.
  • Screen display attributes: timeout period of a connection, number of rows and columns displayed on a terminal screen, and buffer size for historical commands. These attributes determine terminal screen display for console port login.


  1. Run:


    The system view is displayed.

  2. Run:

    user-interface console 0

    The console user interface view is displayed.

  3. Configure data transmission attributes.


    The data transmission attributes configured on the terminal software must be the same as those on the device.

    1. Run:

      speed speed-value

      The transmission rate is set.

      The default transmission rate is 9600 bit/s.

    2. Run:

      flow-control { hardware | none | software }

      The flow control mode is set.

      The default flow control mode is set to none, indicating that the flow control function is not performed.

    3. Run:

      databits { 5 | 6 | 7 | 8 }

      The data bit is set.

      The default data bit is 8. Data bit configuration depends on the code type used for information interchange. If standard ASCII codes are used, set the data bit to 7. If extended ASCII codes are used, set the data bit to 8.

    4. Run:

      parity { even | mark | none | odd | space }

      The parity bit is set.

      The default parity bit is set to none, indicating that the parity check is not performed on the console port. You can set a parity bit to improve data security. If packets on the console port fail to pass the parity check, the device discards the packets.

    5. Run:

      stopbits { 1 | 1.5 | 2 }

      The stop bit is set.

      The default stop bit is 1. The stop bit indicates the end of a packet. More stop bits indicate lower transmission efficiency.

  4. Configure screen display attributes.
    1. Run:

      idle-timeout minutes [ seconds ]

      A timeout period is set for a user connection.

      If a connection remains idle for the specified timeout period, the system automatically ends the connection after the timeout period expires.

      The default timeout period is 10 minutes.


      If you set the timeout period of a terminal connection to 0 or too long, the terminal remains logged in to a device, which is a potential security risk. You are recommended to run the lock command to lock the connection.

    2. Run:

      screen-length screen-length [ temporary ]

      The number of rows displayed on a terminal screen is set.

      temporary specifies the number of rows temporarily displayed on a terminal screen. If you specify this parameter, the configured value does not take effect on the next login.

      The default number of rows displayed on a terminal screen is 24.

    3. Run:

      screen-width screen-width

      The number of columns displayed on a terminal screen is set.

      The default number of columns displayed on a terminal screen is 80. Each character is a column.


      This command is valid only for information displayed by the display interface description command.

    4. Run:

      history-command max-size size-value

      A buffer size is set for historical commands.

      The default buffer size is 10, that is, a maximum of 10 historical commands can be buffered.
