Example for Configuring the Console User Interface

In this configuration example, the physical attributes, terminal attributes, user level, authentication mode, and password are configured for the console user interface. After the configuration is complete, you can log in to the device through the console port in password authentication mode.

Networking Requirements

To initialize the configurations of a new device or locally maintain the device, log in to the device through the console user interface. You can configure attributes for the console user interface based on use and security requirements.

Precautions

Configuration Roadmap

The configuration roadmap is as follows:

Configure physical attributes for the console user interface.
Configure terminal attributes for the console user interface.
Set a user level.
Set an authentication mode and password.

The user name and password do not have default values. Other parameters have default values, which are recommended.

Data Preparation

To complete the configuration, you need the following data:

Transmission rate of a connection: 4800 bit/s
Flow control mode: none
Parity: even
Stopbits: 2
Databits: 6
Timeout period of an idle connection: 30 minutes
Number of rows displayed on a terminal screen: 30
Buffer size for historical commands: 20
User level: 15
Authentication mode: password authentication

Procedure

Configure physical attributes for the console user interface.

<HUAWEI> system-view
[~HUAWEI] user-interface console 0
[~HUAWEI-ui-console0] speed 4800
[*HUAWEI-ui-console0] flow-control none
[*HUAWEI-ui-console0] parity even
[*HUAWEI-ui-console0] stopbits 2
[*HUAWEI-ui-console0] databits 6
[*HUAWEI-ui-console0] commit

Configure terminal attributes for the console user interface.

[~HUAWEI-ui-console0] shell
[*HUAWEI-ui-console0] idle-timeout 30
[*HUAWEI-ui-console0] screen-length 30
[*HUAWEI-ui-console0] history-command max-size 20
[*HUAWEI-ui-console0] commit

Set a user level for the console user interface.

[~HUAWEI-ui-console0] user privilege level 15
[*HUAWEI-ui-console0] commit

Configure password authentication for the console user interface.
```
[~HUAWEI-ui-console0] authentication-mode password
[~HUAWEI-ui-console0] set authentication-mode password
Please configure the login password (8-16)
Enter Password:
Confirm Password:
```
The password must meet the following requirements:
- The 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 exclude question marks (?) and spaces. However, spaces are allowed in the password if the password is enclosed in quotation marks.
  - 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.
```
[*HUAWEI-ui-console0] commit
[~HUAWEI-ui-console0] quit
```
After the console user interface has been configured, you can log in to the device through the console port in password authentication mode. For information about how to log in to the system through the console port, see Configuring Login Through a Console Port.

Verify the configuration.

After completing the configurations, run the display user-interface command to view the configuration of Console 0.
