DGS-1510 Series Gigabit Ethernet SmartPro Switch CLI Reference Guide

1.Introduction

This manual’s command descriptions are based on the software release 1.00. 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.

DGS-1510 Series Gigabit Ethernet SmartPro Switch CLI Reference Guide

NOTE: A note indicates important information that helps you make better use of your device.

NOTICE: A notice indicates either potential damage to hardware or loss of data and tells you how to avoid the problem.

CAUTION: A caution indicates a potential for property damage, personal injury, or death.

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 five 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.

•Advanced User - Privilege Level 3. This user account level is allowed to configure the terminal control setting. This user account can only show limited information that is not related to security.

•Power User - Privilege 8. This user account level can execute fewer commands than operator, including configuration commands other than the operator level and administrator level commands.

•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.

2

DGS-1510 Series Gigabit Ethernet SmartPro Switch CLI Reference Guide

•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 level will log into the Switch in the User EXEC Mode.

•Users with advanced user, power-user, 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 advanced user, power-user, 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/	Purpose
Privilege Level
User EXEC Mode /	This level has the lowest priority of the user accounts. It is provided only
Basic User level	to check basic system settings.
Privileged EXEC Mode /	This level is allowed to configure the terminal control setting. This user
Advanced User level	account can only show limited information that is not related to security.
Privileged EXEC Mode /	This level can execute less commands than operator, include the
Power User level	configure commands other than the operator level and administrator
	level commands.

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 /	This level is identical to privileged EXEC mode at the operator level,

3

DGS-1510 Series Gigabit Ethernet SmartPro Switch CLI Reference Guide

Administrator 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 /	For applying global settings on the entire switch. In addition to applying
Administrator level	global settings on the entire switch, the user can access other sub-
	configuration modes from global configuration mode.
Interface Configuration Mode	For applying interface related settings.
/ Administrator level
VLAN Interface Configuration	For applying VLAN interface related settings.
Mode
VLAN Configuration Mode	For applying settings to a VLAN.
IP Access-List Configuration	For specifying filtering criteria for an IP access list.
Mode

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 Advanced User Level

This command mode is mainly designed for checking basic system settings, allowing users to change the local terminal session settings and carrying out basic network connectivity verification. One limitation of this command mode is that it cannot be used to display information related to security. This command mode can be entered by logging in as an advanced user.

Privileged EXEC Mode at Power User Level

User logged into the Switch in privileged EXEC mode at this level can execute fewer commands than operator, including the configuration commands other than the operator level and administrator level commands. The method to enter privileged EXEC mode at power user level is to login to the Switch with a user account that has a privileged level of 8.

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.

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:

4

DGS-1510 Series Gigabit Ethernet SmartPro Switch CLI Reference Guide

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

By default, there is no user account created on this switch. For security reasons, it is highly recommended to create user accounts to manage and control access to this switch’s interface. This section will assist a user with creating a user account by means of the Command Line Interface.

Observe the following example.

Switch>enable

Switch#configure terminal

Switch(config)#username admin password admin

Switch(config)#username admin 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 admin password admin creates a user account with the username of admin and a password of admin.

•The command username admin 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.

5

DGS-1510 Series Gigabit Ethernet SmartPro Switch CLI Reference Guide

•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’ll 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’ll 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 doesn’t support any open

6

DGS-1510 Series Gigabit Ethernet SmartPro Switch CLI Reference Guide

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	The command was entered incorrectly.
^marker

The following example shows how an ambiguous command error message is generated.

Switch# show v

Ambiguous command

Switch#

The following example shows how an incomplete command error message is generated.

Switch# show

Incomplete command

Switch#

The following example shows how an invalid input error message is generated.

Switch# show verb

^

Invalid input detected at ^marker Switch#

Editing Features

The command line interface of this switch supports to following keyboard keystroke editing features.

	Keystroke	Description
	Delete	Deletes the character under the cursor and shifts the remainder of the
		line to the left.
	Backspace	Deletes the character to the left of the cursor and shifts the remainder
		of the line to the left.
	Left Arrow	Moves the cursor to the left.
	Right Arrow	Moves the cursor to the right.

7

DGS-1510 Series Gigabit Ethernet SmartPro Switch CLI Reference Guide

CTRL+R	Toggles the insert text function on and off. When on, text can be
	inserted in the line and the remainder of the text will be shifted to the
	right. When off, text can be inserted in the line and old text will
	automatically be replaced with the new text.
Return	Scrolls down to display the next line or used to issue a command.
Space	Scrolls down to display the next page.
ESC	Escapes from the displaying page.

Display Result Output Modifiers

Results displayed by show commands can be filtered using the following parameters:

•begin FILTER-STRING - This parameter is used to start the display with the first line that matches the filter string.

•include FILTER-STRING - This parameter is used to display all the lines that match the filter string.

•exclude FILTER-STRING - This parameter is used to exclude the lines that match the filter string from the display.

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.

10

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

2-2 enable

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:

14

DGS-1510 Series Gigabit Ethernet SmartPro Switch CLI Reference Guide

•When AAA is enabled, the AAA module is used.

•When AAA is disabled, the following rules are used:

o When login is disabled, the username and password is ignored. Enter the details at Level 1.

o When 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.

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 the command to reset to the default setting.

dot1x control-direction {both | in} no dot1x control-direction

Parameters

24

		DGS-1510 Series Gigabit Ethernet SmartPro Switch CLI Reference Guide
	both	Specifies to enable bidirectional control for the port.
	in	Specifies to enable in direction control for the port.

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 forceauthorized, 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 forceunauthorized, 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)#
