1.1.1 CLI Overview
H3C S3610&S5510 Series Ethernet Switches provide a series of configuration
commands and command line interface for you to configure and maintain the Ethernet
switches. The command line interface is featured by the following:
z Configure the command levels to make sure that unauthorized users cannot use
related commands to configure a switch.
z You can enter <?> at any time to get the online help.
z Provide network test commands, such as tracert, and ping, to help you to
diagnose the network.
z Provide plenty of detail debugging information to help you to diagnose and locate
the network failures.
z Provide a function similar to Doskey to execute a history command.
z Adopt the partial match method to search for the keywords of a command line.
You only need to enter a non-conflicting keyword to execute the command
correctly.
1.1.2 Online Help with Command Lines
The following are the types of online help available with the CLI:

Stops the display and the command
execution.
1.1.4 History Command
The CLI can automatically save the commands that have been entered. You can invoke
and repeatedly execute them whenever needed. By default, the CLI can save up to ten
commands for each user. But you can configure the history command buffer size of the
current user interface by using the history-command max-size command. For details
about the command, refer to the Login module.
Table 1-2 lists the operation that you can perform.

Note:
You may use arrow keys to access history commands in Windows 2000/XP Terminal or
Telnet. However, the up-arrow and down-arrow keys are invalid in Windows 9X
HyperTerminal, because they are defined in a different way. You can use <Ctrl+P> and
<Ctrl+N> instead.
1.1.5 Command Line Error Information
The commands are executed only if they have no syntax error. Otherwise, error
information is reported.
Table 1-3 lists some common errors.

match at all, the system will not modify the incomplete keyword
and display it again in the next line.
1.1.7 CLI Views
CLI views are designed for different configuration tasks. They are interrelated. You will
enter user view once you log into a switch successfully, where you can perform
operations such as displaying operation status and statistical information. And by
executing the system-view command, you can enter system view, where you can
enter other views by executing the corresponding commands.
The following CLI views are provided:
z User view
z System view

1.2.5 Configuring Welcome Information
I. Introduction to welcome information
Welcome information is a piece of prompt displayed when a user connects to a device
for logging and interoperation. The administrator is allowed to configure the banner as
the situation requires.
For the time being, there are five kinds of banners available:
z Shell welcome information or session banner, displayed when you enter console
session.
z User interface welcome information or incoming banner, displayed when a user
interface is enabled by TTY Modem.
z Logging welcome information or login banner, displayed when the user configures
password authentication and scheme authentication,
z MOTD welcome information, displayed before the authentication is started.
z Authorization welcome information or legal banner. When a user logins into a
device, the system displays some copyright or authorization information and a
legal banner and waits for confirmation of the user. If the user enters “Y” or the
<Enter> key, the authentication or login process continues; if the user enters “N”,
the authentication or login process breaks. "Y” and “N” are case-insensitive.
II. Configuring welcome information
There are two modes to configure welcome information:
The first mode is to enter all the welcome content right after the command keywords in
one line. The beginning character and the end character of the entered content must be
the same, but the two characters are not part of the welcome information. In this case,
the command keywords, the beginning and end characters, and the welcome
information altogether must not exceed 510 characters. The second mode is to enter
the welcome content in two or more lines, each line ended with an <Enter> key. In this
case, the content may be up to 2000 characters.
You can enter contents in multiple lines in three ways:
z Straight <Enter> in the first line: End the configuration with “%”. The <Enter> and
“%” characters are not included in the banner content.
z One character followed with <Enter> in the first line: End the configuration with the
character entered in the first line. The character entered in the first line and the
ending character are not included in the banner content.
z Multiple characters (the leading and ending characters are different) followed with
<Enter> in the first line: End the configuration with the first character of the first line.
The first character of the first line and the ending character are not included in the
banner content.

Note:
These hotkeys are defined by the system. When a user interacts with the device from
terminal software, they may be defined to perform other operations. If so, the definition
of the terminal software will dominate.
1.2.7 Configuring User Levels and Command Levels
Corresponding to the command levels, the system categorizes users into 4 levels. A
user can perform only the commands that have the command levels equal to or below
the user level.
The command levels include visit, monitor, system and management, as the following:
z Visit: Used for network diagnosing commands (ping, tracert), commands sent to
outer devices (including Telnet client, SSH client, RLOGIN), etc. Commands of
this level cannot save configuration files.
z Monitor: Used for system maintaining, service troubleshooting, etc, including
commands such as refresh, reset and send. Commands of this level cannot save
configuration files.
z System: Used for service configuration, including commands of routing and
different network layers. Commands of this level provide users with direct network
services.
z Management: Used for commands related to system running and system support
modules, including file system, FTP, TFTP, Xmodem download, configuration file
switching, power control, backup board control, user management, level
configuration and interim system parameter configuration (non-protocol and
non-RFC).
You need to enhance your user level to obtain privileges to use commands of higher
levels. When switching the user level, you are required to enter the corresponding
password for the sake of security. The password entered is not displayed on the screen.
If it is entered correctly within three times, the user level is switched to a higher level.
You can specify the command level and its view as required. Every command has its
own default view and privilege and you don’t have to re-configure it.
