Command Descriptions
The information pertaining t o 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 privile ge 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
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 lev el wil l 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.
DGS-1510 Series Gigabit Ethernet SmartPro Switch CLI Reference Guide
3
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 access ed 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 sub­configuration 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 sub­configuration 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
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.
DGS-1510 Series Gigabit Ethernet SmartPro Switch CLI Reference Guide
4
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 Mo de 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
5
NOTE: After upgrading the f irm ware on the Switc h and no user acc ounts w ere created,
the default admin user ac c ount wi ll automatically be created after rebooting the Switch with the new boot-up configuration file.
NOTE: After upgrading the f irm ware on the Switc h and user accounts were created, the
default admin user account will not be created automatically. Only after a factory reset was performed on the Switch will the default admin user account be created.
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 pas s word 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#
DGS-1510 Series Gigabit Ethernet SmartPro Switch CLI Reference Guide

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 Switc h 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 Sw itch to recognize the
command.
Incomplete command The command was not entered with all the required keyword.

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.
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 '?'.

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:
○ When login is disabled, the username and password is ignored. Enter the details at Level
1.
○ When the username and password option is selected, use the username and password
setup by the username command.
○ When 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.

Parameters
all
Specifies to clear 802.1X counters (diagnostics, statistics and
session statistics) on all interfaces.
interface INTERFACE-ID
Specifies to clear 802.1X counters (diagnostics, statistics and
session statistics) on the specified interface. Val id int er f aces are
physical ports (including type, stack member, and port number).
,
(Optional) Specifies a series of interfaces, or separate a range of
interfaces from a previous range. No space is allowed before and
after the comma.
-
(Optional) Specifies a range of interfaces. No space is allowed
before and after the hyphen.
Default
None.
Command Mode
Privileged EXEC Mode.
Command Default Level
Level: 12.
Usage Guideline

Example
This example shows how to clear 802.1X counters (diagnostics, statistics and session stati stics) on the Ethernet port 1/0/1.
Switch# clear dot1x counters interface eth1/0/1 Switch#
3-2 dot1x control-direction
This command is used to configure the direction of the traffic on a controlled port as unidirectional (in) or bidirectional (both). Use the no form of this command to revert to the default setting.
dot1x control-direction {both | in} no dot1x control-direction
Parameters
both
Specifies to enable bidirectional control for the port.
in
Specifies to enable in direction control for the port.
DGS-1510 Series Gigabit Ethernet SmartPro Switch CLI Reference Guide
25
Default
By default, this option is bidirectional mode.
Command Mode
Interface Configuration Mode.
Command Default Level
Level: 12.
Usage Guideline
This command is only available for physical port interface configuration. If the port control is set to force-authorized, then the port is not controlled in both directions. If the port control is set to auto, then the access to the port for the controlled direction needs to be authenticated. If the port control is set to force-unauthorized, then the access to the port for the controlled direction is blocked.
Suppose that port control is set to auto. If the control direction is set to both, then the port can receive and transmit EAPOL packets only. All user traffic is blocked before authentication. If the control direction is set to in, then in addition to receiving and transmitting EAPOL packets, the port can transmit user traffic but not receive user traffic before authentication.
Example
This example shows how to configure the controlled direction of the traffic through Ethernet eth1/0/1 as unidirectional.
Switch# configure terminal Switch(config)# interface eth1/0/1 Switch(config-if)# dot1x control-direction in Switch(config-if)#
3-3 dot1x default
This command is used to reset the IEEE 802.1X parameters on a specific port to their default settings.
dot1x default
Parameters
None.
Default
IEEE 802.1X authentication is disabled. Control direction is bidirectional (both). Port control is auto. Forward PDU on port is disabled. Maximum request is 2 times. Server timer is 30 seconds. Supplicant timer is 30 seconds. Transmit interval is 30 seconds.
Command Mode
Interface Configuration Mode.
Command Default Level
Level: 12.
DGS-1510 Series Gigabit Ethernet SmartPro Switch CLI Reference Guide

Parameters
auto
Specifies to enable IEEE 802.1X authentication for the port.
force-authorized
Specifies the port to the force authorized state.
force-unauthorized
Specifies the port to the force unauthorized state.
Default
By default, this option is set as auto.
Command Mode
Interface Configuration Mode.
Command Default Level
Level: 12.
Usage Guideline
This command takes effect only when IEEE 802.1X PAE authenticator is globally enabled by the dot1x system-auth-control command and is enabled for a specific port by using the dot1x PAE authenticator.
This command is only available for physical port interface configuration. If the port control is set to force-authorized, then the port is not controlled in both directions. If the
port control is set to auto, then the access to the port for the controlled direction needs to be authenticated. If the port control is set to force-unauthorized, then the access to the port for the controlled direction is blocked.
Example
This example shows how to deny all access on Ethernet port 1/0/1.
