Preface
Version Description
This manual’s command descriptions are based on the software release 2.00.022. The
commands listed here are the subset of commands that are supported by the DGS-6600
series switches.
Note: Other Ethernet L2/L3 Chassis-Based Switch series Hardware using similar software
may support a different subset of commands although generally the majority of the supported
commands and options will be similar.
Audience
This reference manual is intended for network administrators and other IT networking
professionals responsible for managing the DGS-6604 by using the D-LINK Command Line
Reference (CLI). The CLI is the primary management interface to the D-LINK DGS-6604
which will be generally referred to as the “switch” within this manual. This manual is written in
a way that assumes that you already have the experience and knowledge of Ethernet and
modern networking principles for Local Area Networks.

Command Descriptions:
The information pertaining to each command in this reference guide is presented using a number of
template fields. The fields are:
• Description - This is a short and consise statement describing the commands functionality.
• Syntax - The precise form to use when entering and issuing the command. The form conventions
are described in the table shown under the section “Conventions” on page v of this guide.
• Syntax Description - A table where each row describes the optional or required arguments, and
their use, that can be issued with the command.
• Default - If the command sets a configuration value or administrative state of the switch then any
default settings (i.e. without issuing the command) of the configuration is shown here.
• Command Mode - The mode in which the command can be issued. The modes are either User
EXEC, Privileged EXEC, Global Configuration or a specific configuration mode. These modes are
described in the section titled “Command Modes” on page vi below.
•Command Usage - If necessary, a detailed description of the command and its various utilization
scenarios is given here.
• Example(s) - Each command is accompanied by a practical example of the command being
issued in a suitable scenario.
Command Modes
There are several command modes available in the command-line interface (CLI). The set of commands
available to the user depends on both the mode the user is currently in and their privilege level. For each
case, the user can see all the commands that are available in a particular command mode by entering a
question mark (?) at the system prompt.
The command-line interface has four privilege levels:
•Basic User- Privilege Level 1. This user account level has the lowest priority of the user accounts
and is allowed to configure the terminal control settings. The purpose of this type of user account
level is for basic system checking. This user account can only show limited information that is not
related to security. The most important limitation of this account is that there is no way of changing
the access right level.
•Advanced User- Privilege Level 2. This user account level is very similar to a basic user except
that an advanced user can enter privileged EXEC mode.
•Power User- Privilege Level 12. This user account level is used to grant system configuration
rights for users who need to change or monitor system configuration, except for security related
information such as user accounts and SNMP account settings, etc.
•Administrator- Privilege Level 15. This administrator user account level can monitor all system
information and change any of the system configuration settings expressed in this configuration
guide.
The command-line interface has a number of command modes. There are three basic command modes:

-
vii
• User EXEC mode
• Privileged EXEC mode
•Global Configuration mode
All other sub-configuration modes can be accessed via global configuration mode.
When a user logs in to the Switch, the privilege level of the user determines the command mode the user
will enter after initially logging in. The user will either log into user EXEC mode or privileged EXEC mode.
Users with a basic user and advanced user level will log into the Switch in user EXEC mode. Users with
power user and administrator level accounts will log into the Switch in privileged EXEC mode. Therefore,
user EXEC mode can operate at either basic user level or advanced user level, and privileged EXEC
mode can operate at either power user level or administrator level. The user can only enter global
configuration mode from privileged EXEC mode. Therefore, global configuration mode can be accessed
by users who have power user or administrator level user accounts. As for sub-configuration modes, a
subset of those can only be accessed by users who have the highest secure administrator level
privileges.
In user EXEC mode at advanced user level, the user is allowed to enter privileged EXEC mode by
entering the enable password. In privileged EXEC mode, the user is allowed to exit to the user EXEC
mode at advanced user level by entering the disable command. The enable password and disable
commands are functions that can be used to switch between user EXEC mode and privileged EXEC
mode.

The following table briefly lists the available command modes. Only the basic command modes and some
of the sub-configuration modes are enumerated. The basic command modes and basic sub-configuration
modes are further described in the following chapters. Descriptions for the rest of the sub-configuration
modes are not provided in this section. For more information on the additional sub-configuration modes,
the user should refer to the chapters relating to these functions.
The available command modes and privilege levels are described below:
Note: Not all configuration modes are listed in the above figure. For example, in
global configuration mode, enter “router ospf” to enter OSPF router configuration
mode
Command Mode & Privilege Level Purpose
User EXEC mode at Basic User level For checking basic system settings, allowing users to
change the local terminal session settings, and verifying
basic network connectivity. Checking security related
settings is not allowed at this command mode and
privilege level.
User EXEC mode at Advanced User level This level has almost the same access rights as user
EXEC mode at basic user level, except that a user in this
mode and at this level can enter privileged EXEC mode
by entering the enable command.
Privileged EXEC mode at Power User level For changing both local and global terminal settings,
monitoring, and performing certain system
administration tasks. The system administration tasks
that can be performed at this level includes the clearing
of system configuration settings, except for any security
related information, such as user accounts, SNMP
account settings etc.
Privileged EXEC mode at Administrator
level
This level is identical to privileged EXEC mode at power
user level, except that a user at the administrator level
can monitor and clear security related settings.
Global Configuration Mode at Power User
level
For applying global settings, except for security related
settings, on the entire Switch. In addition to applying
global settings on the entire Switch, the user can access
other sub-configuration modes from global configuration
mode.
Global Configuration Mode at Administrator
level
For applying global settings on the entire Switch. In
addition to applying global settings on the entire Switch,
the user can access other sub-configuration modes from
global configuration mode.
Interface Configuration Mode at Power
User level
For applying interface related settings.

User EXEC Mode at Basic User Level
This command mode is mainly designed for checking basic system settings, allowing users to change the
local terminal session settings and carry out basic network connectivity verification. One limitation of this
command mode is that it cannot be used to display information related to security. The most significant
limitation of this command mode is that there is no way of changing the access right level of the logged in
user.
This command mode can be entered by logging in as a basic user.
User EXEC Mode at Advanced User Level
User EXEC mode at advanced user level has the same purpose as user EXEC mode at basic user level,
except that user EXEC mode at advanced user level is allowed to use the enable command to enter
privileged EXEC mode.
This command mode can be entered by logging in as an advanced user or by using the disable
command in privileged EXEC mode.
In the following example, the user is currently logged in as an advanced user in privileged EXEC mode
and uses the disable command to return to user EXEC mode at advanced user level:
Privileged EXEC Mode at Power User Level
Users logged into the Switch in privileged EXEC mode at this level can change both local and global
terminal settings, monitor, and perform system administration tasks like clearing configuration settings
(except for security related information such as user accounts, SNMP account settings etc.)
There are two methods that a user can use to enter privileged EXEC mode at power user level. The first
method is to login to the Switch with a user account that has a privilege level of 12. The other method is to
use the enable privilege LEVEL command in user EXEC mode.
In the following example, the user enters privileged EXEC mode at power user level by logging in with a
user account called “power-user” that has a privilege level of 12:
VLAN Interface Configuration Mode For applying VLAN interface related settings.
VLAN Configuration Mode For applying settings to a VLAN.
IP Access-List Configuration Mode For specifying filtering criteria for an IP access list.

In the following example, the user enters the enable privilege LEVEL command in user EXEC mode to
enter privileged EXEC mode at Power User level:
Privileged EXEC Mode at Administrator Level
This command mode has a privilege level of 15. Users logged in with this command mode can monitor all
system information and change any system configuration settings mentioned in this Configuration Guide.
There are two methods that a user can use to enter privileged EXEC mode at administrator level. The first
method is to login to the Switch with a user account that has a privilege level of 15. The second method
requires a user to login to the Switch in as a user with an advanced user or power user level and and use
the enable privilege LEVEL command.
In this command mode, the user can return to user EXEC mode at an advanced user level by entering the
disable command.
In the following example, the user is currently logged in as an administrator in privileged EXEC mode and
uses the disable command to return to user EXEC mode at an advanced user level:

In the following example, the user enters the enable privilege LEVEL command in privileged EXEC
mode at power user level to enter privileged EXEC mode at an administrator level:
Global Configuration Mode
The primary purpose of global configuration mode is to apply global settings on the entire Switch. Global
configuration mode can be accessed at both power user and administrator level. However, security
related settings are not accessible at power user level. In addition to applying global settings on the entire
Switch, the user can also access other sub-configuration modes.
In order to access global configuration mode, the user must be logged in as an administrator or power
user and use the configure terminal command in privileged EXEC mode.
In the following example, the user is logged in as an Administrator in privileged EXEC mode and uses the
configure terminal command to access global configuration mode:
The exit command is used to exit global configuration mode and return to privileged EXEC mode.
The procedures to enter the different sub-configuration modes can be found in the related chapters in this
Configuration Guide. The command modes are used to configure the individual functions.
Interface Configuration Mode
Interface configuration mode is used to configure the parameters for an interface or a range of interfaces.
An interface can be a physical port, VLAN, or other virtual interface. Thus, interface configuration mode is
distinguished further according to the type of interface. The command prompt for each type of interface is
slightly different.
VLAN Interface Configuration Mode
VLAN interface configuration mode is one of the available interface modes and is used to configure the
parameters of a VLAN interface.
To access VLAN interface configuration mode, use the following command in global configuration mode:
DGS-6604:12#enable privilege 15
DGS-6604:15#
DGS-6604:15#configure terminal
DGS-6604:15(config)#
Command Explanation
DGS-6604:15(config)#interface
vlanVLAN-ID
Enters VLAN interface configuration mode.
