1SYSTEM OPERATION BASICS

1.1 Overview

System operation basics mainly describe the basic knowledge of device operations, including

device configuration modes, command modes, and command line interface.

1.2 System Operation Basic Functions

1.2.1 Device Configuration Modes

Users can log in to the device for configuration and management in different modes. (For

details of the login modes, refer to the chapter "System login" in the configuration guide.) The

device provides four typical configuration modes:

Logging in to the device locally through the Console port. By default, users can configure

the device directly in this mode.

Logging in to the device by remote dial-up through a Modem. The device cannot be

configured directly in this mode, that is, before configuration, some preparations need to

be made.

Logging in to the device remotely through Telnet. The device cannot be configured directly

in this mode, that is, before configuration, some preparations need to be made.

Logging in to the device remotely through SSH. The device cannot be configured directly in

this mode, that is, before configuration, some preparations need to be made.

1.2.2 Command Operating Modes

The device provides a command processing subsystem for management and execution of

system commands. The subsystem shell provides the following main functions:

Registration of system commands

Editing of system configuration commands by users

Parsing of the commands that have been inputted by users

Execution of system commands

If a user configures the device through shell commands, the system provides multiple

operating modes for the execution of the commands. Each command mode supports specific

Configuration manual

configuration commands. In this way, hierarchical protection is provided to the system,

protecting the system from unauthorized access.

The shell subsystem provides multiple modes for the operating of configuration commands.

These modes have different system prompts, prompting the current system mode of the user.

The following lists common configuration modes:

Common user mode (user EXEC)

Privileged user mode (privilege EXEC)

Global configuration mode (global configuration)

Interface configuration mode (interface configuration)

File system configuration mode (file system configuration)

Access list configuration mode (access list configuration)

Other configuration modes (They will be described in the related sections and chapters.)

The following table shows how to enter the common command modes and switch over

between the modes.

Hostname is the system name. In global configuration mode, a user can run

the hostname command to modify the system name, and the modification

takes effect immediately.

If a user is not in privileged user mode while the user wants to run a

privileged mode command, the user can use the do command to run the

required command without the need to returning back to the privileged

mode. (For details, refer to the related sections in "System Operation

Basics" of the command manual.) Note that the mode switchover command

such as do configure terminal is not included.

1.2.3 Command Line Interface

The command line interface is a man-machine interface that is provided by the shell subsystem

to configure and use the device. With the command line interface, users can input and edit

commands to perform the required configuration tasks, and they can also query the system

information and learn the system operation status.

The command line interface provides the following functions for the users:

System help information management

System command inputting and editing

History command management

Terminal display system management

Command Line Online Help

The command line provides the following types of online help:

Help

Full help

Partial help

With the above types of online help, users can obtain various help information. The following

gives some examples.

To obtain a brief description of the online help system, run the help command in any

command mode.

Hostname#help

Help may be requested at any point in a command by entering

a question mark '?'. If nothing matches, the help list will

be empty and you must backup until entering a '?' shows the

available options.

Two styles of help for command are provided:

1. Full help is available when you are ready to enter a

command argument (e.g. 'show ?') and describes each possible

argument.

2. Partial help is provided when an abbreviated argument is entered

and you want to know what arguments match the input

(e.g. 'show pr?'.)

And "Edit key" usage is the following:

CTRL+A -- go to home of current line

CTRL+E -- go to end of current line

CTRL+U -- erase all character from home to current cursor

CTRL+K -- erase all character from current cursor to end

CTRL+W -- erase a word on the left of current cursor

CTRL+R -- erase a word on the right of current cursor

CTRL+D,DEL -- erase a character on current cursor

BACKSPACE -- erase a character on the left of current cursor

CTRL+B,LEFT -- current cursor backward a character

CTRL+F,RIGHT -- current cursor forward a character

To list all commands and their brief description in any command mode, type "?" in the

command mode.
