through CLI.

router by entering commands on CLI.

commands based on the corresponding level.
z

Accounting (AAA) to prevent the unauthorized user from accessing the router.
z

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.
z
The system supports the command with 255 characters at most. The command can be in an
incomplete form.
z
The system saves the incomplete command to the configuration files in the complete form; therefore,
the command may have more than 255 characters. However, when the system is restarted, the
incomplete command cannot be restored. So, pay attention to the length of the incomplete command.
3.1.2 Command Levels
The system adopts a hierarchical protection mode that has 16 command levels.
The default command level are as follows:
z
Level 0-Visit level: Commands of this level include commands of network diagnosis tool
(such as ping and tracert) and commands that start from the local device and visit
external device (including Telnet client side, SSH client side and Rlogin) and so on.
