Command Line Interface

The Command Line Interface (CLI) is a common tool for users to perform configurations on the device. After a user logs in to the device, the command line prompt is displayed, that is, the CLI is displayed.

The system provides a series of configuration commands. You can configure and manage the device by entering commands on CLI.

The characteristics of CLI are as follows:

• Local configuration through console port.

• Local or remote configuration through Telnet or Secure Shell (SSH).

• A user interface view for specific configuration management.

• Hierarchical command protection for users of different levels, that is, running the commands of the corresponding level.

• Local authentication, password authentication and Authentication, Authorization and Accounting (AAA) to prevent the unauthorized user from accessing the device.

• Entering "?" for online help at any time.

• Network testing commands such as tracert and ping for rapidly diagnosing a network.

• Abundant debugging information to help in diagnosing the network.

• The telnet command for directly logging in to and manage other device.

• FTP service for file uploading and downloading.

• Running a history command, like DosKey.

• A command line interpreter provides intelligent command resolution methods such as key word fuzzy match and context conjunction. These methods make it easy for users to enter their commands.

You can enter a maximum of 899 characters when you enter a command on the CLI. If you execute the incomplete syntax of a command, ensure that the complete syntax of this command does not exceed 899 characters because all commands are restored in complete syntax upon restart. In this case, you need to configure the user-defined information, such as the name and description, briefly.
