Warnings and Notes
These are how warnings and notes are shown in this CLI Reference Guide.
1 Warnings tell you about things that could harm you or your device. See your
User’s Guide for product specific warnings.
" Notes tell you other important information (for example, other things you may
need to configure or helpful tips) or recommendations.
Syntax Conventions
This manual follows these general conventions:
ZyXELs switches (such as the ES-2024A, ES-2108, GS-3012, and so on) may be referred
to as the “Switch”, the “device”, the “system” or the “product” in this Reference Guide.
Units of measurement may denote the “metric” value or the “scientific” value. For
example, “k” for kilo may denote “1000” or “1024”, “M” for mega may denote “1000000”
or “1048576” and so on.
Command descriptions follow these conventions:
Commands are in
courier new font.
Required input values are in angle brackets <>; for example,
ping <ip> means that you
must specify an IP address for this command.
Optional fields are in square brackets []; for instance show logins [name], the name
field is optional.
The following is an example of a required field within an optional field: snmp-server
[contact <system contact>], the contact field is optional. However, if you
use contact, then you must provide the system contact information.
Lists (such as <port-list>) consist of one or more elements separated by commas.
Each element might be a single value (1, 2, 3, ...) or a range of values (1-2, 3-5, ...)
separated by a dash.
•The | (bar) symbol means “or”.
italic terms represent user-defined input values; for example, in snmp-server
[contact <system contact>], system contact can be replaced by the
administrators name.
A key stroke is denoted by square brackets and uppercase text, for example, [ENTER]
means the “Enter” or “Return” key on your keyboard.

<cr> means press the [ENTER] key.
An arrow (-->) indicates that this line is a continuation of the previous line.
Command summary tables are organized as follows:
The Table title identifies commands or the specific feature that the commands configure.
The COMMAND column shows the syntax of the command.
If a command is not indented, you run it in the enable or config mode. See Chapter 2 on
page 19 for more information on command modes.
If a command is indented, you run it in a sub-command mode.
The DESCRIPTION column explains what the command does. It also identifies legal input
values, if necessary.
The M column identifies the mode in which you run the command.
E: The command is available in enable mode. It is also available in user mode if the
privilege level (P) is less than 13.
C: The command is available in config (not indented) or one of the sub-command modes
(indented).
The P column identifies the privilege level of the command. If you don’t have a high enough
privilege level you may not be able to view or execute some of the commands. See Chapter 2
on page 19 for more information on privilege levels.

1.4 Saving Your Configuration
When you run a command, the Switch saves any changes to its run-time memory. The Switch
loses these changes if it is turned off or loses power. Use the
write memory command in
enable mode to save the current configuration permanently to non-volatile memory.
" You should save your changes after each CLI session. All unsaved
configuration changes are lost once you restart the Switch.
1.5 Logging Out
Enter logout to log out of the CLI. You have to be in user, enable, or config mode. See
Chapter 2 on page 19 for more information about modes.

CHAPTER 2
Privilege Level and Command
Mode
This chapter introduces the CLI privilege levels and command modes.
The privilege level determines whether or not a user can run a particular command.
If a user can run a particular command, the user has to run it in the correct mode.
2.1 Privilege Levels
Every command has a privilege level (0-14). Users can run a command if the session’s
privilege level is greater than or equal to the command’s privilege level. The session’s
privilege level initially comes from the login account’s privilege level, though it is possible to
change the session’s privilege level after logging in.
2.1.1 Privilege Levels for Commands
The privilege level of each command is listed in the Reference A-G chapters on page 29.
At the time of writing, commands have a privilege level of 0, 3, 13, or 14. The following table
summarizes the types of commands at each of these privilege levels.
2.1.2 Privilege Levels for Login Accounts
You can manage the privilege levels for login accounts in the following ways:
Using commands. Login accounts can be configured by the admin account or any login
account with a privilege level of 14. See Chapter 38 on page 177.
Table 6 Types of Commands at Different Privilege Levels
PRIVILEGE LEVEL TYPES OF COMMANDS AT THIS PRIVILEGE LEVEL
0 Display basic system information.
3 Display configuration or status.
13 Configure features except for login accounts, SNMP user accounts, the
authentication method sequence and authorization settings, multiple logins,
administrator and enable passwords, and configuration information display.
14 Configure login accounts, SNMP user accounts, the authentication method
sequence and authorization settings, multiple logins, and administrator and
enable passwords, and display configuration information.
Chapter 2 Privilege Level and Command Mode
Ethernet Switch CLI Reference Guide
20
Using vendor-specific attributes in an external authentication server. See the Users Guide
for more information.
The admin account has a privilege level of 14, so the administrator can run every command.
You cannot change the privilege level of the admin account.
2.1.3 Privilege Levels for Sessions
The session’s privilege level initially comes from the privilege level of the login account the
user used to log in to the Switch. After logging in, the user can use the following commands to
change the session’s privilege level.
2.1.3.1 enable Command
This command raises the session’s privilege level to 14. It also changes the session to enable
mode (if not already in enable mode). This command is available in user mode or enable
mode, and users have to know the enable password.
In the following example, the login account user0 has a privilege level of 0 but knows that the
enable password is 123456. Afterwards, the session’s privilege level is 14, instead of 0, and
the session changes to enable mode.
The default enable password is 1234. Use this command to set the enable password.
password <password>
<password> consists of 1-32 alphanumeric characters. For example, the following
command sets the enable password to 123456. See Chapter 85 on page 319 for more
information about this command.
The password is sent in plain text and stored in the Switch’s buffers. Use this command to set
the cipher password for password encryption.
password cipher <password>
<password> consists of 32 alphanumeric characters. For example, the following command
encrypts the enable password with a 32-character cipher password. See Chapter 50 on page
213 for more information about this command.
2.1.3.2 enable <0-14> Command
This command raises the session’s privilege level to the specified level. It also changes the
session to enable mode, if the specified level is 13 or 14. This command is available in user
mode or enable mode, and users have to know the password for the specified privilege level.
