1. Introduction
This manual’s command descriptions are based on the software release 1.30. The commands listed
here are the subset of commands that are supported by the DGS-1510 Series SmartPro Switch.
Audience
This CLI Reference Guide is intended for network administrators and other IT networking
professionals responsible for managing the switch by using the Command Line Interface (CLI). The
CLI is the primary management interface to the DGS-1510 Series SmartPro Switch, which will be
generally be referred to simply 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 concise statement describing the commands functionality.
Syntax - The precise form to use when entering and issuing the command.
Parameters - A table where each row describes the optional or required parameters, 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. These modes are
described in the section titled “Command Modes” below.
Command Default Level –The user privilege level in which the command can be issued.
Usage Guideline - 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 three pre-defined privilege levels:
Basic User - Privilege Level 1. This user account level has the lowest priority of the user
accounts. The purpose of this type of user account level is for basic system checking.
Operator - 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:
User EXEC Mode
Privileged EXEC Mode
Global Configuration Mode

DGS-1510 Series Gigabit Ethernet SmartPro Switch CLI Reference Guide
3
All other sub-configuration modes can be accessed via the 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 the Privileged
EXEC Mode.
Users with a basic user level will log into the Switch in the User EXEC Mode.
Users with operator or administrator level accounts will log into the Switch in the Privileged
EXEC Mode.
Therefore, the User EXEC Mode can operate at a basic user level and the Privileged EXEC Mode can
operate at the operator, or administrator levels. The user can only enter the Global Configuration
Mode from the Privileged EXEC Mode. The Global Configuration Mode can be accessed by users
who have operator 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.
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:
Command Mode /
Privilege Level
Purpose
User EXEC Mode /
Basic User level
This level has the lowest priority of the user accounts. It is provided
only to check basic system settings.
Privileged EXEC Mode /
Operator 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 except for any
security related information.
Privileged EXEC Mode /
Administrator level
This level is identical to privileged EXEC mode at the operator level,
except that a user at the administrator level can monitor and clear
security related settings.
Global Configuration Mode /
Operator 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 /
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
/ Administrator level
For applying interface related settings.
VLAN Interface Configuration
Mode
For applying VLAN interface related settings.
User EXEC Mode at Basic User Level
This command mode is mainly designed for checking basic system settings. This command mode can
be entered by logging in as a basic user.
Privileged EXEC Mode at Operator Level

DGS-1510 Series Gigabit Ethernet SmartPro Switch CLI Reference Guide
4
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 (except for security related
information). The method to enter privileged EXEC mode at operator level is to login to the Switch
with a user account that has a privilege level of 12.
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. The method to enter privileged EXEC mode at administrator level is to login to
the Switch with a user account that has a privilege level of 15.
Global Configuration Mode
The primary purpose of the global configuration mode is to apply global settings on the entire switch.
Global configuration mode can be accessed at operator or administrator level user accounts. However,
security related settings are not accessible at operator user account. In addition to applying global
settings on the entire switch, the user can also access other sub-configuration modes. In order to
access the global configuration mode, the user must be logged in with the corresponding account
level and use the configure terminal command in the privileged EXEC mode.
In the following example, the user is logged in as an Administrator in the Privileged EXEC Mode and
uses the configure terminal command to access the Global Configuration Mode:
Switch# configure terminal
Switch(config)#
The exit command is used to exit the global configuration mode and return to the privileged EXEC
mode.
Switch(config)# exit
Switch#
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:
Switch(config)# interface vlan 1
Switch(config-if)#
Creating a User Account
You can create different user account for various levels. This section will assist a user with creating a
user account by means of the Command Line Interface.
NOTE: By default, one user account is already configured on the Switch. Both the
username and password for this account is admin, and the privilege level is 15.

DGS-1510 Series Gigabit Ethernet SmartPro Switch CLI Reference Guide

Observe the following example.
Switch>enable
Switch#configure terminal
Switch(config)#username user1 password pass1234
Switch(config)#username user1 privilege 15
Switch(config)#line console
Switch(config-line)#login local
Switch(config-line)#
In the above example we had to navigate and access the username command.
Starting in the User EXEC Mode we enter the command enable to access the Privileged
EXEC Mode.
After accessing the Privileged EXEC Mode, we entered the command configure terminal to
access the Global Configuration Mode. The username command can be used in the Global
Configuration Mode.
The command username user1 password pass1234 creates a user account with the
username of user1 and a password of pass1234.
The command username user1 privilege 15 assigns a privilege level value of 15 to the user
account admin.
The command line console allows us to access the console interface’s Line Configuration
Mode.
The command login local tell the Switch that users need to enter locally configured login
credentials to access the console interface.
Save the running configuration to the start-up configuration. This means to save the changes made so
that when the Switch is rebooted, the configuration will not be lost. The following example shows how
to save the running configuration to the start-up configuration.
Switch#copy running-config startup-config
Destination filename startup-config? [y/n]: y
Saving all configurations to NV-RAM.......... Done.
Switch#
After the Switch was rebooted, or when the users logs out and back in, the newly created username
and password must be entered to access the CLI interface again, as seen below.

Interface Notation
When configuration the physical ports available on this switch, a specific interface notation is used.
The following will explain the layout, terminology and use of this notation.
In the following example, we will enter the Global Configuration Mode and then enter the Interface
Configuration Mode, using the notation 1/0/1. After entering the Interface Configuration Mode for port
1, we will change the speed to 1 Gbps, using the speed 1000 command.
Switch# configure terminal
Switch(config)# interface Ethernet 1/0/1
Switch(config-if)# speed 1000
Switch(config-if)#
In the above example the notation 1/0/1 was used. The terminology for each parameter is as follows:
Interface Unit’s ID / Open Slot’s ID / Port’s ID
The Interface Unit’s ID is the ID of the stacking unit without the physical stack. If stacking is disabled
or this unit is a stand-alone unit, then this parameter is irrelevant. The Open Slot’s ID is the ID of the
module plugged into the open module slot of the Switch. The DGS-1510 Series does not support any
open modules slots, thus this parameters will always by zero for this switch series. Lastly, the Port’s
ID is the physical port number of the port being configured.
In summary the above example will configure the stacked switch with the ID of 1, with the open slot ID
of 0, and the physical port number 1.
Error Messages
When the users issue a command that the Switch does not recognize, error messages will be
generated to assist users with basic information about the mistake that was made. A list of possible
error messages are found in the table below.
Error Message
Meaning
Ambiguous command
Not enough keywords were entered for the Switch to recognize the
command.
Incomplete command
The command was not entered with all the required keyword.
Invalid input detected at

2. Basic CLI Commands
2-1 help
This command is used to display a brief description of the help system. Use the help command in any
command mode.
help
Parameters
None.
Default
None.
Command Mode
EXEC Mode or Any Configuration Mode.
Command Default Level
Level: 1.
Usage Guideline
The help command provides a brief description for the help system, which includes the following
functions:
To list all commands available for a particular command mode, enter a question mark (?) at
the system prompt.
To obtain a list of commands that begin with a particular character string, enter the
abbreviated command entry immediately followed by a question mark (?). This form of help is
called word help, because it lists only the keywords or arguments that begin with the
abbreviation entered.
To list the keywords and arguments associated with a command, enter a question mark (?) in
place of a keyword or argument on the command line. This form of help is called the
command syntax help, because it lists the keywords or arguments that apply based on the
command, keywords, and arguments already entered.
Example
This example shows how the help command is used to display a brief description of the help system.

DGS-1510 Series Gigabit Ethernet SmartPro Switch CLI Reference Guide

Switch#help
The switch CLI provides advanced help feature.
1. Help is available when you are ready to enter a command
argument (e.g. 'show ?') and want to know each possible
available options.
2. Help is provided when an abbreviated argument is entered
and you want to know what arguments match the input(e.g. 'show ve?'.).
If nothing matches, the help list will be empty and you must backup
until entering a '?' shows the available options.
3. For completing a partial command name could enter the abbreviated
command name immediately followed by a <Tab> key.
Note:
Since the character '?' is used for help purpose, to enter
the character '?' in a string argument, press ctrl+v immediately
followed by the character '?'.
Switch#
The following example shows how to use the word help to display all the Privileged EXEC Mode
commands that begin with the letters “re”. The letters entered before the question mark (?) are
reprinted on the next command line to allow the user to continue entering the command.
Switch#re?
reboot rename renew reset
Switch#re
The following example shows how to use the command syntax help to display the next argument of
a partially complete IP access-list standard command. The characters entered before the question
mark (?) is reprinted on the next command line to allow the user to continue entering the command.
Switch(config)#ip access-list standard ?
<1-1999> Standard IP access-list number
<cr>
Switch(config)#ip access-list standard

2-6 login (Line)
This command is used to set the line login method. Use the no form of this command to disable the
login.
login [local]
no login
Parameters
login
Specifies that the line login method will be login.
local
Specifies that the line login method will be local.
Default
By default, all line interfaces use the login local method (by username and password).
Command Mode
Line Configuration Mode.
Command Default Level
Level: 15.
Usage Guideline
For Console and Telnet access, when AAA is enabled, the line uses rules configured by the AAA
module. When AAA is disabled, the line uses the following authentication rules:
When login is disabled, the user can enter the line at Level 1.
When the by password option is selected, after inputting the same password as the
command password, the user enter the line at level 1. If the password wasn’t previously
configured an error message will be displayed and the session will be closed.
When the username and password option is selected, enter the username and password
configured by the username command.
For SSH access, there are three authentication types:
SSH public key,
Host-based authentication, and
Password authentication.
The SSH public key and host-based authentication types are independent from the login command in
the line mode. If the authentication type is password, the following rules apply:
When AAA is enabled, the AAA module is used.
When AAA is disabled, the following rules are used:
oWhen login is disabled, the username and password is ignored. Enter the details at
Level 1.
oWhen the username and password option is selected, use the username and
password setup by the username command.
oWhen the password option is selected, the username is ignored but a password is
required using the password command to enter the line at level 1.
Example
This example shows how to enter the Line Configuration Mode and to create a password for the line
user. This password only takes effect once the corresponding line is set to login.
Switch# configure terminal
Switch(config)# line console
Switch(config-line)# password loginpassword
Switch(config-line)#
